+  We introduce group membership in 6.0 as a replacement for teams.
+  The old combination of groups and teams was confusing for a lot of people.
+  And when the members of a team where changed this wasn't reflected in the project permissions.
+  In GitLab 6.0 you will be able to add members to a group with a permission level for each member.
+  These group members will have access to the projects in that group.
+  Any changes to group members will immediately be reflected in the project permissions.
+  You can even have multiple owners for a group, greatly simplifying administration.

+## Experimental Redis Sentinel support
+
+> [Introduced][ce-1877] in GitLab 8.11.
+
+Since GitLab 8.11, you can configure a list of Redis Sentinel servers that
+will monitor a group of Redis servers to provide you with a standard failover
+support.
+
+There is currently one exception to the Sentinel support: `mail_room`, the
+component that processes incoming emails. It doesn't support Sentinel yet, but
+we hope to integrate a future release that does support it.
+
+To get a better understanding on how to correctly setup Sentinel, please read
+the [Redis Sentinel documentation](http://redis.io/topics/sentinel) first, as
+failing to configure it correctly can lead to data loss.
+
+The configuration consists of three parts:
+
+- Redis setup
+- Sentinel setup
+- GitLab setup
+
+Read carefully how to configure those components below.
+
+### Redis setup
+
+You must have at least 2 Redis servers: 1 Master, 1 or more Slaves.
+They should be configured the same way and with similar server specs, as
+in a failover situation, any Slave can be elected as the new Master by
+the Sentinel servers.
+
+In a minimal setup, the only required change for the slaves in `redis.conf`
+is the addition of a `slaveof` line pointing to the initial master.
+You can increase the security by defining a `requirepass` configuration in
+the master, and `masterauth` in slaves.
+
+---
+
+**Configuring your own Redis server**
+
+1. Add to the slaves' `redis.conf`:
+
+    ```conf
+    # IP and port of the master Redis server
+    slaveof 10.10.10.10 6379
+    ```
+
+1. Optionally, set up password authentication for increased security.
+   Add the following to master's `redis.conf`:
+
+    ```conf
+    # Optional password authentication for increased security
+    requirepass "<password>"
+    ```
+
+1. Then add this line to all the slave servers' `redis.conf`:
+
+    ```conf
+    masterauth "<password>"
+    ```
+
+1. Restart the Redis services for the changes to take effect.
+
+---
+
+**Using Redis via Omnibus**
+
+1. Edit `/etc/gitlab/gitlab.rb` of a master Redis machine (usualy a single machine):
+
+    ```ruby
+    ## Redis TCP support (will disable UNIX socket transport)
+    redis['bind'] = '0.0.0.0' # or specify an IP to bind to a single one
+    redis['port'] = 6379
+
+    ## Master redis instance
+    redis['password'] = '<huge password string here>'
+    ```
+
+1. Edit `/etc/gitlab/gitlab.rb` of a slave Redis machine (should be one or more machines):
+
+    ```ruby
+    ## Redis TCP support (will disable UNIX socket transport)
+    redis['bind'] = '0.0.0.0' # or specify an IP to bind to a single one
+    redis['port'] = 6379
+
+    ## Slave redis instance
+    redis['master_ip'] = '10.10.10.10' # IP of master Redis server
+    redis['master_port'] = 6379 # Port of master Redis server
+    redis['master_password'] = "<huge password string here>"
+    ```
+
+1. Reconfigure the GitLab for the changes to take effect: `sudo gitlab-ctl reconfigure`
+
+---
+
+Now that the Redis servers are all set up, let's configure the Sentinel
+servers.
+
+### Sentinel setup
+
+We don't provide yet an automated way to setup and run the Sentinel daemon
+from Omnibus installation method. You must follow the instructions below and
+run it by yourself.
+
+The support for Sentinel in Ruby has some [caveats](https://github.com/redis/redis-rb/issues/531).
+While you can give any name for the `master-group-name` part of the
+configuration, as in this example:
+
+```conf
+sentinel monitor <master-group-name> <ip> <port> <quorum>
+```
+
+,for it to work in Ruby, you have to use the "hostname" of the master Redis
+server, otherwise you will get an error message like:
+`Redis::CannotConnectError: No sentinels available.`. Read
+[Sentinel troubleshooting](#sentinel-troubleshooting) for more information.
+
+Here is an example configuration file (`sentinel.conf`) for a Sentinel node:
+
+```conf
+port 26379
+sentinel monitor master-redis.example.com 10.10.10.10 6379 1
+sentinel down-after-milliseconds master-redis.example.com 10000
+sentinel config-epoch master-redis.example.com 0
+sentinel leader-epoch master-redis.example.com 0
+```
+
+---
+
+The final part is to inform the main GitLab application server of the Redis
+master and the new sentinels servers.
+
+### GitLab setup
+
+You can enable or disable sentinel support at any time in new or existing
+installations. From the GitLab application perspective, all it requires is
+the correct credentials for the master Redis and for a few Sentinel nodes.
+
+It doesn't require a list of all Sentinel nodes, as in case of a failure,
+the application will need to query only one of them.
+
+>**Note:**
+The following steps should be performed in the [GitLab application server](gitlab.md).
+
+**For source based installations**
+
+1. Edit `/home/git/gitlab/config/resque.yml` following the example in
+   `/home/git/gitlab/config/resque.yml.example`, and uncomment the sentinels
+   line, changing to the correct server credentials.
+1. Restart GitLab for the changes to take effect.
+
+**For Omnibus installations**
+
+1. Edit `/etc/gitlab/gitlab.rb` and add/change the following lines:
+
+    ```ruby
+    gitlab-rails['redis_host'] = "master-redis.example.com"
+    gitlab-rails['redis_port'] = 6379
+    gitlab-rails['redis_password'] = '<huge password string here>'
+    gitlab-rails['redis_sentinels'] = [
+      {'host' => '10.10.10.1', 'port' => 26379},
+      {'host' => '10.10.10.2', 'port' => 26379},
+      {'host' => '10.10.10.3', 'port' => 26379}
+    ]
+    ```
+
+1. [Reconfigure] the GitLab for the changes to take effect.
+
+### Sentinel troubleshooting
+
+If you get an error like: `Redis::CannotConnectError: No sentinels available.`,
+there may be something wrong with your configuration files or it can be related
+to [this issue][gh-531] ([pull request][gh-534] that should make things better).
+
+It's a bit rigid the way you have to config `resque.yml` and `sentinel.conf`,
+otherwise `redis-rb` will not work properly.
+
+The hostname ('my-primary-redis') of the primary Redis server (`sentinel.conf`)
+**must** match the one configured in GitLab (`resque.yml` for source installations
+or `gitlab-rails['redis_*']` in Omnibus) and it must be valid ex:
+
+```conf
+# sentinel.conf:
+sentinel monitor my-primary-redis 10.10.10.10 6379 1
+sentinel down-after-milliseconds my-primary-redis 10000
+sentinel config-epoch my-primary-redis 0
+sentinel leader-epoch my-primary-redis 0
+```
+
+```yaml
+# resque.yaml
+production:
+  url: redis://my-primary-redis:6378
+  sentinels:
+    -
+      host: slave1
+      port: 26380 # point to sentinel, not to redis port
+    -
+      host: slave2
+      port: 26381 # point to sentinel, not to redis port
+```
+
+When in doubt, please read [Redis Sentinel documentation](http://redis.io/topics/sentinel)
+
+---
+
+To make sure your configuration is correct:
+
+1. SSH into your GitLab application server
+1. Enter the Rails console:
+
+    ```
+    # For Omnibus installations
+    sudo gitlab-rails console
+
+    # For source installations
+    sudo -u git rails console RAILS_ENV=production
+    ```
+
+1. Run in the console:
+
+    ```ruby
+    redis = Redis.new(Gitlab::Redis.params)
+    redis.info
+    ```
+
+    Keep this screen open and try to simulate a failover below.
+
+1. To simulate a failover on master Redis, SSH into the Redis server and run:
+
+    ```bash
+    # port must match your master redis port
+     redis-cli -h localhost -p 6379 DEBUG sleep 60
+    ```
+
+1. Then back in the Rails console from the first step, run:
+
+    ```
+    redis.info
+    ```
+
+    You should see a different port after a few seconds delay
+    (the failover/reconnect time).

+# Koding & GitLab
+
+> [Introduced][ce-5909] in GitLab 8.11.
+
+This document will guide you through installing and configuring Koding with
+GitLab.
+
+First of all, to be able to use Koding and GitLab together you will need public
+access to your server. This allows you to use single sign-on from GitLab to
+Koding and using vms from cloud providers like AWS. Koding has a registry for
+VMs, called Kontrol and it runs on the same server as Koding itself, VMs from
+cloud providers register themselves to Kontrol via the agent that we put into
+provisioned VMs. This agent is called Klient and it provides Koding to access
+and manage the target machine.
+
+Kontrol and Klient are based on another technology called
+[Kite](https://github.com/koding/kite), that we have written at Koding. Which is a
+microservice framework that allows you to develop microservices easily.
+
+## Requirements
+
+### Hardware
+
+Minimum requirements are;
+
+  - 2 cores CPU
+  - 3G RAM
+  - 10G Storage
+
+If you plan to use AWS to install Koding it is recommended that you use at
+least a `c3.xlarge` instance.
+
+### Software
+
+  - [Git](https://git-scm.com)
+  - [Docker](https://www.docker.com)
+  - [docker-compose](https://www.docker.com/products/docker-compose)
+
+Koding can run on most of the UNIX based operating systems, since it's shipped
+as containerized with Docker support, it can work on any operating system that
+supports Docker.
+
+Required services are:
+
+- **PostgreSQL** - Kontrol and Service DB provider
+- **MongoDB**    - Main DB provider the application
+- **Redis**      - In memory DB used by both application and services
+- **RabbitMQ**   - Message Queue for both application and services
+
+which are also provided as a Docker container by Koding.
+
+
+## Getting Started with Development Versions
+
+
+### Koding
+
+You can run `docker-compose` environment for developing koding by
+executing commands in the following snippet.
+
+```bash
+git clone https://github.com/koding/koding.git
+cd koding
+docker-compose up
+```
+
+This should start koding on `localhost:8090`.
+
+By default there is no team exists in Koding DB. You'll need to create a team
+called `gitlab` which is the default team name for GitLab integration in the
+configuration. To make things in order it's recommended to create the `gitlab`
+team first thing after setting up Koding.
+
+
+### GitLab
+
+To install GitLab to your environment for development purposes it's recommended
+to use GitLab Development Kit which you can get it from
+[here](https://gitlab.com/gitlab-org/gitlab-development-kit).
+
+After all those steps, gitlab should be running on `localhost:3000`
+
+
+## Integration
+
+Integration includes following components;
+
+  - Single Sign On with OAuth from GitLab to Koding
+  - System Hook integration for handling GitLab events on Koding
+    (`project_created`, `user_joined` etc.)
+  - Service endpoints for importing/executing stacks from GitLab to Koding
+    (`Run/Try on IDE (Koding)` buttons on GitLab Projects, Issues, MRs)
+
+As it's pointed out before, you will need public access to this machine that
+you've installed Koding and GitLab on. Better to use a domain but a static IP
+is also fine.
+
+For IP based installation you can use [xip.io](https://xip.io) service which is
+free and provides DNS resolution to IP based requests like following;
+
+  - 127.0.0.1.xip.io              -> resolves to 127.0.0.1
+  - foo.bar.baz.127.0.0.1.xip.io  -> resolves to 127.0.0.1
+  - and so on...
+
+As Koding needs subdomains for team names; `foo.127.0.0.1.xip.io` requests for
+a running koding instance on `127.0.0.1` server will be handled as `foo` team
+requests.
+
+
+### GitLab Side
+
+You need to enable Koding integration from Settings under Admin Area. To do
+that login with an Admin account and do followings;
+
+ - open [http://127.0.0.1:3000/admin/application_settings](http://127.0.0.1:3000/admin/application_settings)
+ - scroll to bottom of the page until Koding section
+ - check `Enable Koding` checkbox
+ - provide GitLab team page for running Koding instance as `Koding URL`*
+
+* For `Koding URL` you need to provide the gitlab integration enabled team on
+your Koding installation. Team called `gitlab` has integration on Koding out
+of the box, so if you didn't change anything your team on Koding should be
+`gitlab`.
+
+So, if your Koding is running on `http://1.2.3.4.xip.io:8090` your URL needs
+to be `http://gitlab.1.2.3.4.xip.io:8090`. You need to provide the same host
+with your Koding installation here.
+
+
+#### Registering Koding for OAuth integration
+
+We need `Application ID` and `Secret` to enable login to Koding via GitLab
+feature and to do that you need to register running Koding as a new application
+to your running GitLab application. Follow
+[these](http://docs.gitlab.com/ce/integration/oauth_provider.html) steps to
+enable this integration.
+
+Redirect URI should be `http://gitlab.127.0.0.1:8090/-/oauth/gitlab/callback`
+which again you need to _replace `127.0.0.1` with your instance public IP._
+
+Take a copy of `Application ID` and `Secret` that is generated by the GitLab
+application, we will need those on _Koding Part_ of this guide.
+
+
+#### Registering system hooks to Koding (optional)
+
+Koding can take actions based on the events generated by GitLab application.
+This feature is still in progress and only following events are processed by
+Koding at the moment;
+
+  - user_create
+  - user_destroy
+
+All system events are handled but not implemented on Koding side.
+
+To enable this feature you need to provide a `URL` and a `Secret Token` to your
+GitLab application. Open your admin area on your GitLab app from
+[http://127.0.0.1:3000/admin/hooks](http://127.0.0.1:3000/admin/hooks)
+and provide `URL` as `http://gitlab.127.0.0.1:8090/-/api/gitlab` which is the
+endpoint to handle GitLab events on Koding side. Provide a `Secret Token` and
+keep a copy of it, we will need it on _Koding Part_ of this guide.
+
+_(replace `127.0.0.1` with your instance public IP)_
+
+
+### Koding Part
+
+If you followed the steps in GitLab part we should have followings to enable
+Koding part integrations;
+
+  - `Application ID` and `Secret` for OAuth integration
+  - `Secret Token` for system hook integration
+  - Public address of running GitLab instance
+
+
+#### Start Koding with GitLab URL
+
+Now we need to configure Koding with all this information to get things ready.
+If it's already running please stop koding first.
+
+##### From command-line
+
+Replace followings with the ones you got from GitLab part of this guide;
+
+```bash
+cd koding
+docker-compose run                              \
+  --service-ports backend                       \
+  /opt/koding/scripts/bootstrap-container build \
+  --host=**YOUR_IP**.xip.io                     \
+  --gitlabHost=**GITLAB_IP**                    \
+  --gitlabPort=**GITLAB_PORT**                  \
+  --gitlabToken=**SECRET_TOKEN**                \
+  --gitlabAppId=**APPLICATION_ID**              \
+  --gitlabAppSecret=**SECRET**
+```
+
+##### By updating configuration
+
+Alternatively you can update `gitlab` section on
+`config/credentials.default.coffee` like following;
+
+```
+gitlab =
+  host: '**GITLAB_IP**'
+  port: '**GITLAB_PORT**'
+  applicationId: '**APPLICATION_ID**'
+  applicationSecret: '**SECRET**'
+  team: 'gitlab'
+  redirectUri: ''
+  systemHookToken: '**SECRET_TOKEN**'
+  hooksEnabled: yes
+```
+
+and start by only providing the `host`;
+
+```bash
+cd koding
+docker-compose run                              \
+  --service-ports backend                       \
+  /opt/koding/scripts/bootstrap-container build \
+  --host=**YOUR_IP**.xip.io                     \
+```
+
+#### Enable Single Sign On
+
+Once you restarted your Koding and logged in with your username and password
+you need to activate oauth authentication for your user. To do that
+
+ - Navigate to Dashboard on Koding from;
+   `http://gitlab.**YOUR_IP**.xip.io:8090/Home/my-account`
+ - Scroll down to Integrations section
+ - Click on toggle to turn On integration in GitLab integration section
+
+This will redirect you to your GitLab instance and will ask your permission (
+if you are not logged in to GitLab at this point you will be redirected after
+login) once you accept you will be redirected to your Koding instance.
+
+From now on you can login by using `SIGN IN WITH GITLAB` button on your Login
+screen in your Koding instance.

+# Issue closing pattern
+
+>**Note:**
+This is the administration documentation.
+There is a separate [user documentation] on issue closing pattern.
+
+When a commit or merge request resolves one or more issues, it is possible to
+automatically have these issues closed when the commit or merge request lands
+in the project's default branch.
+
+## Change the issue closing pattern
+
+In order to change the pattern you need to have access to the server that GitLab
+is installed on.
+
+The default pattern can be located in [gitlab.yml.example] under the
+"Automatic issue closing" section.
+
+> **Tip:**
+You are advised to use http://rubular.com to test the issue closing pattern.
+Because Rubular doesn't understand `%{issue_ref}`, you can replace this by
+`#\d+` when testing your patterns, which matches only local issue references like `#123`.
+
+**For Omnibus installations**
+
+1. Open `/etc/gitlab/gitlab.rb` with your editor.
+1. Change the value of `gitlab_rails['issue_closing_pattern']` to a regular
+   expression of your liking:

-It basically consists of an exchange of an authorization token for an access token. For more detailed info, check out the [RFC spec here](http://tools.ietf.org/html/rfc6749#section-4.1)
+This is the most common type of flow and is used by server-side clients that wish to access GitLab on a user's behalf.
+
+>**Note:**
+This flow **should not** be used for client-side clients as you would leak your `client_secret`. Client-side clients should use the Implicit Grant (which is currently unsupported).
 
-This flow consists from 3 steps.
+For more detailed information, check out the [RFC spec](http://tools.ietf.org/html/rfc6749#section-4.1)
+
+In the following sections you will be introduced to the three steps needed for this flow.
 
 ### 1. Registering the client
 
-Create an application in user's account profile.
+First, you should create an application (`/profile/applications`) in your user's account.
+Each application gets a unique App ID and App Secret parameters.
+
+>**Note:**
+**You should not share/leak your App ID or App Secret.**
 
 ### 2. Requesting authorization
 
-To request the authorization token, you should visit the `/oauth/authorize` endpoint. You can do that by visiting manually the URL:
+To request the authorization code, you should redirect the user to the `/oauth/authorize` endpoint:
+
+```
+https://gitlab.example.com/oauth/authorize?client_id=APP_ID&redirect_uri=REDIRECT_URI&response_type=code&state=your_unique_state_hash
+```
+
+This will ask the user to approve the applications access to their account and then redirect back to the `REDIRECT_URI` you provided.
+
+The redirect will include the GET `code` parameter, for example:
 
 ```
-http://localhost:3000/oauth/authorize?client_id=APP_ID&redirect_uri=REDIRECT_URI&response_type=code
+http://myapp.com/oauth/redirect?code=1234567890&state=your_unique_state_hash
 ```
 
-Where REDIRECT_URI is the URL in your app where users will be sent after authorization. 	
+You should then use the `code` to request an access token.
+
+>**Important:**
+It is highly recommended that you send a `state` value with the request to `/oauth/authorize` and
+validate that value is returned and matches in the redirect request.
+This is important to prevent [CSRF attacks](http://www.oauthsecurity.com/#user-content-authorization-code-flow),
+`state` really should have been a requirement in the standard!
 
 ### 3. Requesting the access token
 
-To request the access token, you should use the returned code and exchange it for an access token. To do that you can use any HTTP client. In this case, I used rest-client:
+Once you have the authorization code you can request an `access_token` using the code, to do that you can use any HTTP client. In the following example, we are using Ruby's `rest-client`:
 
 ```
 parameters = 'client_id=APP_ID&client_secret=APP_SECRET&code=RETURNED_CODE&grant_type=authorization_code&redirect_uri=REDIRECT_URI'

-In this flow, a token is requested in exchange for the resource owner credentials (username and password). 
+In this flow, a token is requested in exchange for the resource owner credentials (username and password).
 The credentials should only be used when there is a high degree of trust between the resource owner and the client (e.g. the
 client is part of the device operating system or a highly privileged application), and when other authorization grant types are not
 available (such as an authorization code).
 
+>**Important:**
+Never store the users credentials and only use this grant type when your client is deployed to a trusted environment, in 99% of cases [personal access tokens] are a better choice.
+
 Even though this grant type requires direct client access to the resource owner credentials, the resource owner credentials are used
 for a single request and are exchanged for an access token.  This grant type can eliminate the need for the client to store the
 resource owner credentials for future use, by exchanging the credentials with a long-lived access token or refresh token.

+There are build status and test coverage report badges available.

+```markdown
+![coverage](http://gitlab.com/gitlab-org/gitlab-ce/badges/master/coverage.svg?job=coverage)

-# Issue closing pattern
+This document was split into:
 
-When a commit or merge request resolves one or more issues, it is possible to automatically have these issues closed when the commit or merge request lands in the project's default branch.
-
-If a commit message or merge request description contains a sentence matching the regular expression below, all issues referenced from
-the matched text will be closed. This happens when the commit is pushed to a project's default branch, or when a commit or merge request is merged into there.
-
-When not specified, the default `issue_closing_pattern` as shown below will be used:
-
-```bash
-((?:[Cc]los(?:e[sd]?|ing)|[Ff]ix(?:e[sd]|ing)?|[Rr]esolv(?:e[sd]?|ing))(:?) +(?:(?:issues? +)?%{issue_ref}(?:(?:, *| +and +)?)|([A-Z][A-Z0-9_]+-\d+))+)
-```
-
-Here, `%{issue_ref}` is a complex regular expression defined inside GitLab, that matches a reference to a local issue (`#123`), cross-project issue (`group/project#123`) or a link to an issue (`https://gitlab.example.com/group/project/issues/123`).
-
-For example:
-
-```
-git commit -m "Awesome commit message (Fix #20, Fixes #21 and Closes group/otherproject#22). This commit is also related to #17 and fixes #18, #19 and https://gitlab.example.com/group/otherproject/issues/23."
-```
-
-will close `#18`, `#19`, `#20`, and `#21` in the project this commit is pushed to, as well as `#22` and `#23` in group/otherproject. `#17` won't be closed as it does not match the pattern. It also works with multiline commit messages.
-
-Tip: you can test this closing pattern at [http://rubular.com][1]. Use this site
-to test your own patterns.
-Because Rubular doesn't understand `%{issue_ref}`, you can replace this by `#\d+` in testing, which matches only local issue references like `#123`.
-
-## Change the pattern
-
-For Omnibus installs you can change the default pattern in `/etc/gitlab/gitlab.rb`:
-
-```
-issue_closing_pattern: '((?:[Cc]los(?:e[sd]|ing)|[Ff]ix(?:e[sd]|ing)?) +(?:(?:issues? +)?%{issue_ref}(?:(?:, *| +and +)?))+)'
-```
-
-For manual installs you can customize the pattern in [gitlab.yml][0] using the `issue_closing_pattern` key.

+# Adding Database Indexes
+
+Indexes can be used to speed up database queries, but when should you add a new
+index? Traditionally the answer to this question has been to add an index for
+every column used for filtering or joining data. For example, consider the
+following query:
+
+```sql
+SELECT *
+FROM projects
+WHERE user_id = 2;
+```
+
+Here we are filtering by the `user_id` column and as such a developer may decide
+to index this column.
+
+While in certain cases indexing columns using the above approach may make sense
+it can actually have a negative impact. Whenever you write data to a table any
+existing indexes need to be updated. The more indexes there are the slower this
+can potentially become. Indexes can also take up quite some disk space depending
+on the amount of data indexed and the index type. For example, PostgreSQL offers
+"GIN" indexes which can be used to index certain data types that can not be
+indexed by regular btree indexes. These indexes however generally take up more
+data and are slower to update compared to btree indexes.
+
+Because of all this one should not blindly add a new index for every column used
+to filter data by. Instead one should ask themselves the following questions:
+
+1. Can I write my query in such a way that it re-uses as many existing indexes
+   as possible?
+2. Is the data going to be large enough that using an index will actually be
+   faster than just iterating over the rows in the table?
+3. Is the overhead of maintaining the index worth the reduction in query
+   timings?
+
+We'll explore every question in detail below.
+
+## Re-using Queries
+
+The first step is to make sure your query re-uses as many existing indexes as
+possible. For example, consider the following query:
+
+```sql
+SELECT *
+FROM todos
+WHERE user_id = 123
+AND state = 'open';
+```
+
+Now imagine we already have an index on the `user_id` column but not on the
+`state` column. One may think this query will perform badly due to `state` being
+unindexed. In reality the query may perform just fine given the index on
+`user_id` can filter out enough rows.
+
+The best way to determine if indexes are re-used is to run your query using
+`EXPLAIN ANALYZE`. Depending on any extra tables that may be joined and
+other columns being used for filtering you may find an extra index is not going
+to make much (if any) difference. On the other hand you may determine that the
+index _may_ make a difference.
+
+In short:
+
+1. Try to write your query in such a way that it re-uses as many existing
+   indexes as possible.
+2. Run the query using `EXPLAIN ANALYZE` and study the output to find the most
+   ideal query.
+
+## Data Size
+
+A database may decide not to use an index despite it existing in case a regular
+sequence scan (= simply iterating over all existing rows) is faster. This is
+especially the case for small tables.
+
+If a table is expected to grow in size and you expect your query has to filter
+out a lot of rows you may want to consider adding an index. If the table size is
+very small (e.g. only a handful of rows) or any existing indexes filter out
+enough rows you may _not_ want to add a new index.
+
+## Maintenance Overhead
+
+Indexes have to be updated on every table write. In case of PostgreSQL _all_
+existing indexes will be updated whenever data is written to a table. As a
+result of this having many indexes on the same table will slow down writes.
+
+Because of this one should ask themselves: is the reduction in query performance
+worth the overhead of maintaining an extra index?
+
+If adding an index reduces SELECT timings by 5 milliseconds but increases
+INSERT/UPDATE/DELETE timings by 10 milliseconds then the index may not be worth
+it. On the other hand, if SELECT timings are reduced but INSERT/UPDATE/DELETE
+timings are not affected you may want to add the index after all.
+
+## Finding Unused Indexes
+
+To see which indexes are unused you can run the following query:
+
+```sql
+SELECT relname as table_name, indexrelname as index_name, idx_scan, idx_tup_read, idx_tup_fetch, pg_size_pretty(pg_relation_size(indexrelname::regclass))
+FROM pg_stat_all_indexes
+WHERE schemaname = 'public'
+AND idx_scan = 0
+AND idx_tup_read = 0
+AND idx_tup_fetch = 0
+ORDER BY pg_relation_size(indexrelname::regclass) desc;
+```
+
+This query outputs a list containing all indexes that are never used and sorts
+them by indexes sizes in descending order.  This query can be useful to
+determine if any previously indexes are useful after all. More information on
+the meaning of the various columns can be found at
+<https://www.postgresql.org/docs/current/static/monitoring-stats.html>.
+
+Because the output of this query relies on the actual usage of your database it
+may be affected by factors such as (but not limited to):
+
+* Certain queries never being executed, thus not being able to use certain
+  indexes.
+* Certain tables having little data, resulting in PostgreSQL using sequence
+  scans instead of index scans.
+
+In other words, this data is only reliable for a frequently used database with
+plenty of data and with as many GitLab features enabled (and being used) as
+possible.

+- The above `git grep` command will search recursively in the directory you run

+  documentation, sometimes it might be useful to search a path deeper.
+- The `*.md` extension is not used when a document is linked to GitLab's
+  built-in help page, that's why we omit it in `git grep`.

+# Merge Request Performance Guidelines
+
+To ensure a merge request does not negatively impact performance of GitLab
+_every_ merge request **must** adhere to the guidelines outlined in this
+document. There are no exceptions to this rule unless specifically discussed
+with and agreed upon by merge request endbosses and performance specialists.
+
+To measure the impact of a merge request you can use
+[Sherlock](profiling.md#sherlock). It's also highly recommended that you read
+the following guides:
+
+* [Performance Guidelines](performance.md)
+* [What requires downtime?](what_requires_downtime.md)
+
+## Impact Analysis
+
+**Summary:** think about the impact your merge request may have on performance
+and those maintaining a GitLab setup.
+
+Any change submitted can have an impact not only on the application itself but
+also those maintaining it and those keeping it up and running (e.g. production
+engineers). As a result you should think carefully about the impact of your
+merge request on not only the application but also on the people keeping it up
+and running.
+
+Can the queries used potentially take down any critical services and result in
+engineers being woken up in the night? Can a malicious user abuse the code to
+take down a GitLab instance? Will my changes simply make loading a certain page
+slower? Will execution time grow exponentially given enough load or data in the
+database?
+
+These are all questions one should ask themselves before submitting a merge
+request. It may sometimes be difficult to assess the impact, in which case you
+should ask a performance specialist to review your code. See the "Reviewing"
+section below for more information.
+
+## Performance Review
+
+**Summary:** ask performance specialists to review your code if you're not sure
+about the impact.
+
+Sometimes it's hard to assess the impact of a merge request. In this case you
+should ask one of the merge request (mini) endbosses to review your changes. You
+can find a list of these endbosses at <https://about.gitlab.com/team/>. An
+endboss in turn can request a performance specialist to review the changes.
+
+## Query Counts
+
+**Summary:** a merge request **should not** increase the number of executed SQL
+queries unless absolutely necessary.
+
+The number of queries executed by the code modified or added by a merge request
+must not increase unless absolutely necessary. When building features it's
+entirely possible you will need some extra queries, but you should try to keep
+this at a minimum.
+
+As an example, say you introduce a feature that updates a number of database
+rows with the same value. It may be very tempting (and easy) to write this using
+the following pseudo code:
+
+```ruby
+objects_to_update.each do |object|
+  object.some_field = some_value
+  object.save
+end
+```
+
+This will end up running one query for every object to update. This code can
+easily overload a database given enough rows to update or many instances of this
+code running in parallel. This particular problem is known as the
+["N+1 query problem"](http://guides.rubyonrails.org/active_record_querying.html#eager-loading-associations).
+
+In this particular case the workaround is fairly easy:
+
+```ruby
+objects_to_update.update_all(some_field: some_value)
+```
+
+This uses ActiveRecord's `update_all` method to update all rows in a single
+query. This in turn makes it much harder for this code to overload a database.
+
+## Executing Queries in Loops
+
+**Summary:** SQL queries **must not** be executed in a loop unless absolutely
+necessary.
+
+Executing SQL queries in a loop can result in many queries being executed
+depending on the number of iterations in a loop. This may work fine for a
+development environment with little data, but in a production environment this
+can quickly spiral out of control.
+
+There are some cases where this may be needed. If this is the case this should
+be clearly mentioned in the merge request description.
+
+## Eager Loading
+
+**Summary:** always eager load associations when retrieving more than one row.
+
+When retrieving multiple database records for which you need to use any
+associations you **must** eager load these associations. For example, if you're
+retrieving a list of blog posts and you want to display their authors you
+**must** eager load the author associations.
+
+In other words, instead of this:
+
+```ruby
+Post.all.each do |post|
+  puts post.author.name
+end
+```
+
+You should use this:
+
+```ruby
+Post.all.includes(:author).each do |post|
+  puts post.author.name
+end
+```
+
+## Memory Usage
+
+**Summary:** merge requests **must not** increase memory usage unless absolutely
+necessary.
+
+A merge request must not increase the memory usage of GitLab by more than the
+absolute bare minimum required by the code. This means that if you have to parse
+some large document (e.g. an HTML document) it's best to parse it as a stream
+whenever possible, instead of loading the entire input into memory. Sometimes
+this isn't possible, in that case this should be stated explicitly in the merge
+request.
+
+## Lazy Rendering of UI Elements
+
+**Summary:** only render UI elements when they're actually needed.
+
+Certain UI elements may not always be needed. For example, when hovering over a
+diff line there's a small icon displayed that can be used to create a new
+comment. Instead of always rendering these kind of elements they should only be
+rendered when actually needed. This ensures we don't spend time generating
+Haml/HTML when it's not going to be used.
+
+## Instrumenting New Code
+
+**Summary:** always add instrumentation for new classes, modules, and methods.
+
+Newly added classes, modules, and methods must be instrumented. This ensures
+we can track the performance of this code over time.
+
+For more information see [Instrumentation](instrumentation.md). This guide
+describes how to add instrumentation and where to add it.
+
+## Use of Caching
+
+**Summary:** cache data in memory or in Redis when it's needed multiple times in
+a transaction or has to be kept around for a certain time period.
+
+Sometimes certain bits of data have to be re-used in different places during a
+transaction. In these cases this data should be cached in memory to remove the
+need for running complex operations to fetch the data. You should use Redis if
+data should be cached for a certain time period instead of the duration of the
+transaction.
+
+For example, say you process multiple snippets of text containiner username
+mentions (e.g. `Hello @alice` and `How are you doing @alice?`). By caching the
+user objects for every username we can remove the need for running the same
+query for every mention of `@alice`.
+
+Caching data per transaction can be done using
+[RequestStore](https://github.com/steveklabnik/request_store). Caching data in
+Redis can be done using [Rails' caching
+system](http://guides.rubyonrails.org/caching_with_rails.html).

+a max value of 2,147,483,647. Be aware of this when creating a column that will
+hold file sizes in byte units. If you are tracking file size in bytes this
+restricts the maximum file size to just over 2GB.
+
+To allow an integer column to hold up to an 8-byte (64-bit) number, explicitly

+# High Availability on AWS
+
+GitLab on AWS can leverage many of the services that are already
+configurable with High Availability. These services have a lot of
+flexibility and are able to adopt to most companies, best of all is the
+ability to automate both vertical and horizontal scaling.
+
+In this article we'll go through a basic HA setup where we'll start by
+configuring our Virtual Private Cloud and subnets to later integrate
+services such as RDS for our database server and ElastiCache as a Redis
+cluster to finally manage them within an auto scaling group with custom
+scaling policies.
+
+***
+
+## Where to Start
+
+Login to your AWS account through the `My Account` dropdown on
+`https://aws.amazon.com` or through the URI assigned to your team such as
+`https://myteam.signin.aws.amazon.com/console/`. You'll start on the
+Amazon Web Services console from where we can choose all of the services
+we'll be using to configure our cloud infrastructure.
+
+***
+
+## Network
+
+We'll start by creating a VPC for our GitLab cloud infrastructure, then
+we can create subnets to have public and private instances in at least
+two AZs. Public subnets will require a Route Table keep an associated
+Internet Gateway.
+
+### VPC
+
+Start by looking for the VPC option on the web console. Now create a new
+VPC. We can use `10.0.0.0/16` for the CIDR block and leave tenancy as
+default if we don't require dedicated hardware.
+
+![New VPC](img/new_vpc.png)
+
+If you're setting up the Elastic File System service then select the VPC
+and from the Actions dropdown choose Edit DNS Hostnames and select Yes.
+
+### Subnet
+
+Now let's create some subnets in different Availability Zones. Make sure
+that each subnet is associated the the VPC we just created, that it has
+a distinct VPC and lastly that CIDR blocks don't overlap. This will also
+allow us to enable multi AZ for redundancy.
+
+We will create private and public subnets to match load balancers and
+RDS instances as well.
+
+![Subnet Creation](img/subnet.png)
+
+The subnets are listed with their name, AZ and CIDR block:
+
+* gitlab-public-10.0.0.0  - us-west-2a - 10.0.0.0

+
+### Route Table
+
+Up to now all our subnets are private. We need to create a Route Table
+to associate an Internet Gateway. On the same VPC dashboard choose
+Route Tables on the left column and give it a name and associate it to
+our newly created VPC.
+
+![Route Table](img/route_table.png)
+
+
+### Internet Gateway
+
+Now still on the same dashboard head over to Internet Gateways and
+create a new one. After its created pres on the `Attach to VPC` button and
+select our VPC.
+
+![Internet Gateway](img/ig.png)
+
+### Configure Subnets
+
+Go back to the Router Tables screen and select the newly created one,
+press the Routes tab on the bottom section and edit it. We need to add a
+new target which will be our Internet Gateway and have it receive
+traffic from any destination.
+
+![Subnet Config](img/ig-rt.png)
+
+Before leaving this screen select the next tab to the rgiht which is
+Subnet Associations and add our public subnets. If you followed our
+naming convention they should be easy to find.
+
+***
+
+## Database with RDS
+
+For our database server we will use Amazon RDS which offers Multi AZ
+for redundancy. Lets start by creating a subnet group and then we'll
+create the actual RDS instance.
+
+### Subnet Group
+
+From the RDS dashboard select Subnet Groups. Lets select our VPC from
+the VPC ID dropdown and at the bottom we can add our private subnets.
+
+![Subnet Group](img/db-subnet-group.png)
+
+### RDS
+
+Select the RDS service from the Database section and create a new
+PostgreSQL instance. After choosing between a Production or
+Development instance we'll start with the actual configuration. On the
+image bellow we have the settings for this article but note the
+following two options which are of particular interest for HA:
+
+1. Multi-AZ-Deployment is recommended as redundancy. Read more at
+[High Availability (Multi-AZ)](http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Concepts.MultiAZ.html)
+1. While we chose a General Purpose (SSD) for this article a Provisioned
+IOPS (SSD) is best suited for HA. Read more about it at
+[Storage for Amazon RDS](http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/CHAP_Storage.html)
+
+![RDS Instance Specs](img/instance_specs.png)
+
+The rest of the setting on this page request a DB identifier, username
+and a master password. We've chosen to use `gitlab-ha`, `gitlab` and a
+very secure password respectively. Keep these in hand for later.
+
+![Network and Security](img/rds-net-opt.png)
+
+Make sure to choose our gitlab VPC, our subnet group, not have it public,
+and to leave it to create a new security group. The only additional
+change which will be helpful is the database name for which we can use
+`gitlabhq_production`.
+
+***
+
+## ElastiCache
+
+EC is an in-memory hosted caching solution. Redis maintains its own
+persistance and is used for certain types of application.
+
+Let's choose the ElastiCache service in the Database section from our
+AWS console. Now lets create a cache subnet group which will be very
+similar to the RDS subnet group. Make sure to select our VPC and its
+private subnets.
+
+![ElastiCache](img/ec-subnet.png)
+
+Now press the Launch a Cache Cluster and choose Redis for our
+DB engine. You'll be able to configure details such as replication,
+Multi AZ and node types. The second section will allow us to choose our
+subnet and security group and     
+
+![Redis Cluster details](img/redis-cluster-det.png)
+
+![Redis Network](img/redis-net.png)
+
+***
+
+## Elastic File System
+
+This new AWS offering allows us to create a file system accessible by

+EC2 instances within a VPC. Choose our VPC and the subnets will be
+
automatically configured assuming we don't need to set explicit IPs.
+The
next section allows us to add tags and choose between General
+Purpose or
Max I/O which is a good option when being accessed by a
+large number of
EC2 instances.
+
+

![Elastic File System](img/elastic-file-system.png)
+
+To actually mount and install the NFS client we'll use the User Data
+section when adding our Launch Configuration.
+
+***
+
+## Initiate AMI
+
+We are going to launch an EC2 instance and bake an image so that we can
+later use it for auto scaling. We'll also take this opportunity to add an
+extension to our RDS through this temporary EC2 instance.
+
+### EC2 Instance
+
+Look for the EC2 option and choose to create an instance. We'll need at
+least a t2.medium type and for this article we'll choose an Ubuntu 14.04
+HVM 64-bit. In the Configure Instance section choose our GitLab VPC and
+a public subnet. I'd choose at least 10GB of storage.
+
+In the security group we'll create a new one considering that we need to
+SSH into the instance and also try it out through http. So let's add the
+http traffic from anywhere and name it something such as
+`gitlab-ec2-security-group`.
+
+While we wait for it to launch we can allocate an Elastic IP and
+associate it with our new EC2 instance.  
+
+### RDS and Redis Security Group
+
+After the instance is being created we will navigate to our EC2 security
+groups and add a small change for our EC2 instances to be able to
+connect to RDS. First copy the security group name we just defined,
+namely `gitlab-ec2-security-group`, and edit select the RDS security
+group and edit the inbound rules. Choose the rule type to be PostgreSQL
+and paste the name under source.
+
+![RDS security group](img/rds-sec-group.png)
+
+Similar to the above we'll jump to the `gitlab-ec2-security-group` group
+and add a custom TCP rule for port 6379 accessible within itself.
+
+### Install GitLab
+
+To connect through SSH you will need to have the `pem` file which you
+chose available and with the correct permissions such as `400`.
+
+After accessing your server don't forget to update and upgrade your
+packages.
+
+    sudo apt-get update && sudo apt-get upgrade -y
+
+Then follow installation instructions from
+[GitLab](https://about.gitlab.com/downloads-ee/#ubuntu1404), but before
+running reconfigure we need to make sure all our services are tied down
+so just leave the reconfigure command until after we edit our gitlab.rb
+file.
+
+
+### Extension for PostgreSQL
+
+Connect to your new RDS instance to verify access and to install
+a required extension. We can find the host or endpoint by selecting the
+instance and  we just created and after the details drop down we'll find
+it labeled as 'Endpoint'; do remember not to include the colon and port
+number.
+
+    sudo /opt/gitlab/embedded/bin/psql -U gitlab -h <rds-endpoint> -d gitlabhq_production
+    psql (9.4.7)
+    Type "help" for help.
+
+    gitlab=# CREATE EXTENSION pg_trgm;
+    gitlab=# \q
+
+### Configure GitLab
+
+While connected to your server edit the `gitlab.rb` file at `/etc/gitlab/gitlab.rb`
+find the `external_url 'http://gitlab.example.com'` option and change it
+to the domain you will be using or the public IP address of the current
+instance to test the configuration.
+
+For a more detailed description about configuring GitLab read [Configuring GitLab for HA](http://docs.gitlab.com/ee/administration/high_availability/gitlab.html)
+
+Now look for the GitLab database settings and uncomment as necessary. In
+our current case we'll specify the adapter, encoding, host, db name,
+username, and password.
+
+    gitlab_rails['db_adapter'] = "postgresql"
+    gitlab_rails['db_encoding'] = "unicode"    
+    gitlab_rails['db_database'] = "gitlabhq_production"   
+    gitlab_rails['db_username'] = "gitlab"
+    gitlab_rails['db_password'] = "mypassword"
+    gitlab_rails['db_host'] = "<rds-endpoint>"
+
+Next we only need to configure the Redis section by adding the host and
+uncommenting the port.
+
+
+
+The last configuration step is to [change the default file locations ](http://docs.gitlab.com/ee/administration/high_availability/nfs.html)
+to make the EFS integration easier to manage.
+
+    gitlab_rails['redis_host'] = "<redis-endpoint>"
+    gitlab_rails['redis_port'] = 6379
+
+Finally run reconfigure, you might find it useful to run a check and
+a service status to make sure everything has been setup correctly.
+
+    sudo gitlab-ctl reconfigure  
+    sudo gitlab-rake gitlab:check  
+    sudo gitlab-ctl status  
+
+If everything looks good copy the Elastic IP over to your browser and
+test the instance manually.
+
+### AMI
+
+After you finish testing your EC2 instance go back to its dashboard and
+while the instance is selected press on the Actions dropdown to choose
+Image -> Create an Image. Give it a name and description and confirm.
+
+***
+
+## Load Balancer
+
+On the same dashboard look for Load Balancer on the left column and press
+the Create button. Choose a classic Load Balancer, our gitlab VPC, not
+internal and make sure its listening for HTTP and HTTPS on port 80.
+
+Here is a tricky part though, when adding subnets we need to associate
+public subnets instead of the private ones where our instances will
+actually live.
+
+On the secruity group section let's create a new one named
+`gitlab-loadbalancer-sec-group` and allow both HTTP ad HTTPS traffic
+from anywhere.
+
+The Load Balancer Health will allow us to indicate where to ping and what
+makes up a healthy or unhealthy instance.
+
+We won't add the instance on the next session because we'll destroy it
+momentarily as we'll be using the image we where creating. We will keep
+the Enable Cross-Zone and Enable Connection Draining active.
+
+After we finish creating the Load Balancer we can re visit our Security
+Groups to improve access only through the ELB and any other requirement
+you might have.
+
+***
+
+## Auto Scaling Group
+
+Our AMI should be done by now so we can start working on our Auto
+Scaling Group.
+
+This option is also available through the EC2 dashboard on the left
+sidebar. Press on the create button. Select the new image on My AMIs and
+give it a `t2.medium` size. To be able to use Elastic File System we need
+to add a script to mount EFS automatically at launch. We'll do this at
+the Advanced Details section where we have a [User Data](http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/user-data.html)
+text area that allows us to add a lot of custom configurations which
+allows you to add a custom script for when launching an instance. Let's
+add the following script to the User Data section:
+
+
+    #cloud-config
+    package_upgrade: true
+    packages:
+    - nfs-common
+    runcmd:
+    - mkdir -p /gitlab-data
+    - chown ec2-user:ec2-user /gitlab-data
+    - echo "$(curl --silent http://169.254.169.254/latest/meta-data/placement/availability-zone).file-system-id.aws-region.amazonaws.com:/ /gitlab-data nfs defaults,vers=4.1 0 0" >> /etc/fstab
+    - mount -a -t nfs
+    - sudo gitlab-ctl reconfigure
+
+On the security group section we can chosse our existing
+`gitlab-ec2-security-group` group which has already been tested.
+
+After this is launched we are able to start creating our Auto Scaling
+Group. Start by giving it a name and assinging it our VPC and private
+subnets. We also want to always start with two instances and if you
+scroll down to Advanced Details we can choose to receive traffic from ELBs.
+Lets enable that option and select our ELB. We also want to use the ELB's
+health check.
+
+![Auto scaling](img/auto-scaling-det.png)
+
+### Policies
+
+This is the really great part of Auto Scaling, we get to choose when AWS
+launches new instances and when it removes them. For this group we'll
+scale between 2 and 4 instances where one instance will be added if CPU
+utilization is greater than 60% and one instance is removed if it falls
+to less than 45%. Here are the complete policies:
+
+![Policies](img/policies.png)
+
+You'll notice that after we save this AWS starts launching our two
+instances in different AZs and without a public IP which is exactly what
+we where aiming for.
+
+***
+
+## Final Thoughts
+
+After you're done with the policies section have some fun trying to break
+instances. You should be able to see how the Auto Scaling Group and the
+EC2 screen start bringing them up again.
+
+High Availability is a very big area, we went mostly through scaling and
+some redundancy options but it might also imply Geographic replication.
+There is a lot of ground yet to cover so have a read through these other
+resources and feel free to open an issue to request additional material.

+## Suggesting improvements
+
+If you would like to teach a class or participate or help in any way please
+submit a merge request and assign it to [Job](https://gitlab.com/u/JobV).
+
+If you have suggestions for additional courses you would like to see,
+please submit a merge request to add an upcoming class, assign to
+[Chad](https://gitlab.com/u/chadmalchow) and /cc [Job](https://gitlab.com/u/JobV).
+
+## Adding classes
+
+1. All training materials of any kind should be added to [GitLab CE](https://gitlab.com/gitlab-org/gitlab-ce/)
+   to ensure they are available to a broad audience (don't use any other repo or
+   storage for training materials).
+1. Don't make materials that are needlessly specific to one group of people, try
+   to keep the wording broad and inclusive (don't make things for only GitLab Inc.
+   people, only interns, only customers, etc.).
+1. To allow people to contribute all content should be in git.
+1. The content can go in a subdirectory under `/doc/university/`.
+1. To make, view or modify the slides of the classes use [Deckset](http://www.decksetapp.com/)
+   or [RevealJS](http://lab.hakim.se/reveal-js/). Do not use Powerpoint or Google
+   Slides since this prevents everyone from contributing.
+1. Please upload any video recordings to our Youtube channel. We prefer them to
+   be public, if needed they can be unlisted but if so they should be linked from
+   this page.
+1. Please create a merge request and assign to [SeanPackham](https://gitlab.com/u/SeanPackham).

+## Support Boot Camp
+
+**Goal:** Prepare new Service Engineers at GitLab
+
+For each stage there are learning goals and content to support the learning of the engineer.
+The goal of this boot camp is to have every Service Engineer prepared to help our customers
+with whatever needs they might have and to also assist our awesome community with their
+questions.
+
+Always start with the [University Overview](../README.md) and then work
+your way here for more advanced and specific training. Once you feel comfortable
+with the topics of the current stage, move to the next.
+
+### Stage 1
+
+Follow the topics on the [University Overview](../README.md), concentrate on it
+during your first Stage, but also:
+
+- Perform the [first steps](https://about.gitlab.com/handbook/support/onboarding/#first-steps) of
+   the on-boarding process for new Service Engineers
+
+#### Goals
+
+Aim to have a good overview of the Product and main features, Git and the Company
+
+### Stage 2
+
+Continue to look over remaining portions of the [University Overview](../README.md) and continue on to these topics:

+
+#### Become comfortable with the Installation processes that we support
+
+It's important to understand how to install GitLab in the same way that our users do. Try installing different versions and upgrading and downgrading between them. Installation from source will give you a greater understanding of the components that we employ and how everything fits together.
+
+Sometimes we need to upgrade customers from old versions of GitLab to latest, so it's good to get some experience of doing that now.
+
+- [Installation Methods](https://about.gitlab.com/installation/):
+  - [Omnibus](https://gitlab.com/gitlab-org/omnibus-gitlab/)
+  - [Docker](https://gitlab.com/gitlab-org/gitlab-ce/tree/master/docker)

+- Perform a downgrade from [EE to CE](http://doc.gitlab.com/ee/downgrade_ee_to_ce/README.html)
+
+#### Start to learn about some of the integrations that we support
+
+Our integrations add great value to GitLab. User questions often relate to integrating GitLab with existing external services and the configuration involved
+
+- Learn about our Integrations (specially, not only):

+## Git Intro
+
+---
+
+### What is a Version Control System (VCS)
+
+- Records changes to a file
+- Maintains history of changes
+- Disaster Recovery
+- Types of VCS: Local, Centralized and Distributed
+
+---
+
+### Short Story of Git
+
+- 1991-2002: The Linux kernel was being maintaned by sharing archived files
+  and patches.
+- 2002: The Linux kernel project began using a DVCS called BitKeeper
+- 2005: BitKeeper revoked the free-of-charge status and Git was created
+
+---
+
+### What is Git
+
+- Distributed Version Control System
+- Great branching model that adapts well to most workflows
+- Fast and reliable
+- Keeps a complete history
+- Disaster recovery friendly
+- Open Source
+
+---
+
+### Getting Help
+
+- Use the tools at your disposal when you get stuck.
+  - Use `git help <command>` command
+  - Use Google (i.e. StackOverflow, Google groups)
+  - Read documentation at https://git-scm.com
+
+---
+
+## Git Setup
+Workshop Time!
+
+---
+
+### Setup
+
+- Windows: Install 'Git for Windows'
+  - https://git-for-windows.github.io
+- Mac: Type `git` in the Terminal application.
+  - If it's not installed, it will prompt you to install it.
+- Linux
+  - Debian: `sudo apt-get install git-all`
+  - Red Hat `sudo yum install git-all`
+
+---
+
+### Configure
+
+- One-time configuration of the Git client:
+
+```bash
+git config --global user.name "Your Name"
+git config --global user.email you@example.com
+```    
+
+- If you don't use the global flag you can setup a different author for
+  each project
+- Check settings with:
+
+```bash
+git config --global --list
+```
+- You might want or be required to use an SSH key.
+    - Instructions: [SSH](http://doc.gitlab.com/ce/ssh/README.html)
+
+---
+
+### Workspace
+
+- Choose a directory on you machine easy to access
+- Create a workspace or development directory
+- This is where we'll be working and adding content
+
+---
+
+```bash
+mkdir ~/development
+cd ~/development
+
+-or-
+
+mkdir ~/workspace
+cd ~/workspace  
+```
+
+---
+
+## Git Basics
+
+---  
+
+### Git Workflow
+
+- Untracked files
+    - New files that Git has not been told to track previously.
+- Working area (Workspace)
+    - Files that have been modified but are not committed.
+- Staging area (Index)
+    - Modified files that have been marked to go in the next commit.
+- Upstream
+    - Hosted repository on a shared server
+
+---
+
+### GitLab
+
+- GitLab is an application to code, test and deploy.
+- Provides repository management with access controls, code reviews,
+  issue tracking, Merge Requests, and other features.
+- The hosted version of GitLab is gitlab.com
+
+---  
+
+### New Project
+
+- Sign in into your gitlab.com account
+- Create a project
+- Choose to import from 'Any Repo by URL' and use https://gitlab.com/gitlab-org/training-examples.git
+- On your machine clone the `training-examples` project
+
+---
+
+### Git and GitLab basics
+
+1. Edit `edit_this_file.rb` in `training-examples`
+2. See it listed as a changed file (working area)
+3. View the differences
+4. Stage the file
+5. Commit
+6. Push the commit to the remote
+7. View the git log
+
+---
+
+```shell
+# Edit `edit_this_file.rb`
+git status
+git diff
+git add <file>
+git commit -m 'My change'
+git push origin master
+git log
+```
+
+---  
+
+### Feature Branching
+
+1. Create a new feature branch called `squash_some_bugs`
+2. Edit `bugs.rb` and remove all the bugs.
+3. Commit
+4. Push
+
+---
+
+```shell
+git checkout -b squash_some_bugs
+# Edit `bugs.rb`
+git status
+git add bugs.rb
+git commit -m 'Fix some buggy code'
+git push origin squash_some_bugs
+```
+
+---
+
+## Merge Request
+
+---
+
+### Merge requests
+
+- When you want feedback create a merge request
+- Target is the ‘default’ branch (usually master)
+- Assign or mention the person you would like to review
+- Add `WIP` to the title if it's a work in progress
+- When accepting, always delete the branch
+- Anyone can comment, not just the assignee
+- Push corrections to the same branch
+
+
+---
+
+### Merge request example
+
+- Create your first merge request
+  - Use the blue button in the activity feed
+  - View the diff (changes) and leave a comment
+  - Push a new commit to the same branch
+  - Review the changes again and notice the update
+
+---
+
+### Feedback and Collaboration
+
+- Merge requests are a time for feedback and collaboration
+- Giving feedback is hard
+- Be as kind as possible
+- Receiving feedback is hard
+- Be as receptive as possible
+- Feedback is about the best code, not the person. You are not your code
+- Feedback and Collaboration
+
+---
+
+### Feedback and Collaboration
+
+- Review the Thoughtbot code-review guide for suggestions to follow when reviewing merge requests:[Thoughtbot](https://github.com/thoughtbot/guides/tree/master/code-review)
+- See GitLab merge requests for examples: [Merge Requests](https://gitlab.com/gitlab-org/gitlab-ce/merge_requests)
+
+---
+
+## Merge Conflicts
+
+---
+
+### Merge Conflicts
+* Happen often
+* Learning to fix conflicts is hard
+* Practice makes perfect
+* Force push after fixing conflicts. Be careful!
+
+---
+
+### Example Plan
+1. Checkout a new branch and edit conflicts.rb. Add 'Line4' and 'Line5'.
+2. Commit and push
+3. Checkout master and edit conflicts.rb. Add 'Line6' and 'Line7' below 'Line3'.
+4. Commit and push to master
+5. Create a merge request and watch it fail
+6. Rebase our new branch with master
+7. Fix conflicts on the conflicts.rb file.
+8. Stage the file and continue rebasing
+9. Force push the changes
+10. Finally continue with the Merge Request
+
+---
+
+### Example 1/2
+
+    git checkout -b conflicts_branch
+
+    # vi conflicts.rb
+    # Add 'Line4' and 'Line5'
+
+    git commit -am "add line4 and line5"
+    git push origin conflicts_branch
+
+    git checkout master
+
+    # vi conflicts.rb
+    # Add 'Line6' and 'Line7'
+    git commit -am "add line6 and line7"
+    git push origin master
+
+---
+
+### Example 2/2
+
+Create a merge request on the GitLab web UI. You'll see a conflict warning.
+
+    git checkout conflicts_branch
+    git fetch
+    git rebase master
+
+    # Fix conflicts by editing the files.
+
+    git add conflicts.rb
+    # No need to commit this file
+
+    git rebase --continue
+
+    # Remember that we have rewritten our commit history so we
+    # need to force push so that our remote branch is restructured
+    git push origin conflicts_branch -f
+
+---
+
+### Notes
+
+* When to use `git merge` and when to use `git rebase`
+* Rebase when updating your branch with master
+* Merge when bringing changes from feature to master
+* Reference: https://www.atlassian.com/git/tutorials/merging-vs-rebasing/
+
+---
+
+## Revert and Unstage
+
+---
+
+### Unstage
+
+To remove files from stage use reset HEAD. Where HEAD is the last commit of the current branch:
+
+    git reset HEAD <file>
+
+This will unstage the file but maintain the modifications. To revert the file back to the state it was in before the changes we can use:
+
+    git checkout -- <file>
+
+To remove a file from disk and repo use 'git rm' and to rm a dir use the '-r' flag:
+
+    git rm '*.txt'
+    git rm -r <dirname>
+
+If we want to remove a file from the repository but keep it on disk, say we forgot to add it to our .gitignore file then use `--cache`:
+
+    git rm <filename> --cache
+
+---
+
+### Undo Commits
+
+Undo last commit putting everything back into the staging area:
+
+    git reset --soft HEAD^
+
+Add files and change message with:
+
+    git commit --amend -m "New Message"
+
+Undo last and remove changes
+
+    git reset --hard HEAD^
+
+Same as last one but for two commits back:
+
+    git reset --hard HEAD^^
+
+Don't reset after pushing
+
+---
+
+### Reset Workflow
+
+1. Edit file again 'edit_this_file.rb'
+2. Check status
+3. Add and commit with wrong message
+4. Check log
+5. Amend commit
+6. Check log
+7. Soft reset
+8. Check log
+9. Pull for updates
+10. Push changes
+
+----
+
+    # Change file edit_this_file.rb
+    git status
+    git commit -am "kjkfjkg"
+    git log
+    git commit --amend -m "New comment added"
+    git log
+    git reset --soft HEAD^
+    git log
+    git pull origin master
+    git push origin master
+
+---
+
+### Note
+
+git revert vs git reset  
+Reset removes the commit while revert removes the changes but leaves the commit  
+Revert is safer considering we can revert a revert  
+
+
+    # Changed file
+    git commit -am "bug introduced"
+    git revert HEAD
+    # New commit created reverting changes
+    # Now we want to re apply the reverted commit
+    git log # take hash from the revert commit
+    git revert <rev commit hash>
+    # reverted commit is back (new commit created again)
+

+## Questions
+
+---
+
+## Instructor Notes
+
+---
+
+### Version Control
+ - Local VCS was used with a filesystem or a simple db.
+ - Centralized VCS such as Subversion includes collaboration but
+   still is prone to data loss as the main server is the single point of
+   failure.
+ - Distributed VCS enables the team to have a complete copy of the project
+   and work with little dependency to the main server. In case of a main
+   server failing the project can be recovered by any of the latest copies
+   from the team

+
+### 3. Update Ruby
+
+If you are you running Ruby 2.1.x, you do not _need_ to upgrade Ruby yet, but you should note that support for 2.1.x is deprecated and we will require 2.3.x in 8.13. It's strongly recommended that you upgrade as soon as possible.

+sudo -u git -H bundle exec rake assets:clean assets:precompile cache:clear RAILS_ENV=production
+```
+
+### 8. Update configuration files
+
+#### New configuration options for `gitlab.yml`
+
+There are new configuration options available for [`gitlab.yml`](config/gitlab.yml.example). View them with the command below and apply them manually to your current `gitlab.yml`:
+
+```sh
+git diff origin/8-11-stable:config/gitlab.yml.example origin/8-12-stable:config/gitlab.yml.example
+```
+
+#### Git configuration
+
+Configure Git to generate packfile bitmaps (introduced in Git 2.0) on
+the GitLab server during `git gc`.
+
+```sh
+sudo -u git -H git config --global repack.writeBitmaps true
+```
+
+#### Nginx configuration
+
+Ensure you're still up-to-date with the latest NGINX configuration changes:
+
+```sh
+# For HTTPS configurations
+git diff origin/8-11-stable:lib/support/nginx/gitlab-ssl origin/8-12-stable:lib/support/nginx/gitlab-ssl
+
+# For HTTP configurations
+git diff origin/8-11-stable:lib/support/nginx/gitlab origin/8-12-stable:lib/support/nginx/gitlab
+```
+
+If you are using Apache instead of NGINX please see the updated [Apache templates].
+Also note that because Apache does not support upstreams behind Unix sockets you
+will need to let gitlab-workhorse listen on a TCP port. You can do this
+via [/etc/default/gitlab].
+
+[Apache templates]: https://gitlab.com/gitlab-org/gitlab-recipes/tree/master/web-server/apache
+[/etc/default/gitlab]: https://gitlab.com/gitlab-org/gitlab-ce/blob/8-12-stable/lib/support/init.d/gitlab.default.example#L38
+
+#### SMTP configuration
+
+If you're installing from source and use SMTP to deliver mail, you will need to add the following line
+to config/initializers/smtp_settings.rb:
+
+```ruby
+ActionMailer::Base.delivery_method = :smtp
+```
+
+See [smtp_settings.rb.sample] as an example.
+
+[smtp_settings.rb.sample]:  https://gitlab.com/gitlab-org/gitlab-ce/blob/8-12-stable/config/initializers/smtp_settings.rb.sample#L13?
+
+#### Init script
+
+Ensure you're still up-to-date with the latest init script changes:
+
+    sudo cp lib/support/init.d/gitlab /etc/init.d/gitlab
+
+### 9. Start application
+
+    sudo service gitlab start
+    sudo service nginx restart
+
+### 10. Check application status
+
+Check if GitLab and its environment are configured correctly:
+
+    sudo -u git -H bundle exec rake gitlab:env:info RAILS_ENV=production
+
+To make sure you didn't miss anything run a more thorough check:
+
+    sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production
+
+If all items are green, then congratulations, the upgrade is complete!
+
+## Things went south? Revert to previous version (8.11)
+
+### 1. Revert the code to the previous version
+
+Follow the [upgrade guide from 8.10 to 8.11](8.10-to-8.11.md), except for the
+database migration (the backup is already migrated to the previous version).
+
+### 2. Restore from the backup
+
+```bash
+cd /home/git/gitlab
+sudo -u git -H bundle exec rake gitlab:backup:restore RAILS_ENV=production
+```
+
+If you have more than one backup `*.tar` file(s) please add `BACKUP=timestamp_of_backup` to the command above.

+# Two-Factor Authentication
+
+## Recovery options
+
+If you lose your code generation device (such as your mobile phone) and you need
+to disable two-factor authentication on your account, you have several options.
+
+### Use a saved recovery code
+
+When you enabled two-factor authentication for your account, a series of
+recovery codes were generated. If you saved those codes somewhere safe, you
+may use one to sign in.
+
+First, enter your username/email and password on the GitLab sign in page. When
+prompted for a two-factor code, enter one of the recovery codes you saved
+previously.
+
+> **Note:** Once a particular recovery code has been used, it cannot be used again.
+  You may still use the other saved recovery codes at a later time.
+
+### Generate new recovery codes using SSH
+
+It's not uncommon for users to forget to save the recovery codes when enabling
+two-factor authentication. If you have an SSH key added to your GitLab account,
+you can generate a new set of recovery codes using SSH.
+
+Run `ssh git@gitlab.example.com 2fa_recovery_codes`. You will be prompted to
+confirm that you wish to generate new codes. If you choose to continue, any
+previously saved codes will be invalidated.
+
+```bash
+$ ssh git@gitlab.example.com 2fa_recovery_codes
+Are you sure you want to generate new two-factor recovery codes?
+Any existing recovery codes you saved will be invalidated. (yes/no)
+yes
+
+Your two-factor authentication recovery codes are:
+
+119135e5a3ebce8e
+11f6v2a498810dcd
+3924c7ab2089c902
+e79a3398bfe4f224

+b510e7422e81c947
+20dbed24c5e74663
+df9d3b9403b9c9f0
+
+During sign in, use one of the codes above when prompted for
+your two-factor code. Then, visit your Profile Settings and add
+a new device so you do not lose access to your account again.
+```
+
+Next, go to the GitLab sign in page and enter your username/email and password.
+When prompted for a two-factor code, enter one of the recovery codes obtained
+from the command line output.
+
+> **Note:** After signing in, you should immediately visit your **Profile Settings
+  -> Account** to set up two-factor authentication with a new device.
+
+### Ask a GitLab administrator to disable two-factor on your account
+
+If the above two methods are not possible, you may ask a GitLab global
+administrator to disable two-factor authentication for your account. Please
+be aware that this will temporarily leave your account in a less secure state.
+You should sign in and re-enable two-factor authentication as soon as possible
+after the administrator disables it.

+## Downloading the latest build artifacts
+
+It is possible to download the latest artifacts of a build via a well known URL
+so you can use it for scripting purposes.
+
+The structure of the URL is the following:
+
+```
+https://example.com/<namespace>/<project>/builds/artifacts/<ref>/download?job=<job_name>
+```
+
+For example, to download the latest artifacts of the job named `rspec 6 20` of
+the `master` branch of the `gitlab-ce` project that belongs to the `gitlab-org`
+namespace, the URL would be:
+
+```
+https://gitlab.com/gitlab-org/gitlab-ce/builds/artifacts/master/download?job=rspec+6+20
+```
+
+The latest builds are also exposed in the UI in various places. Specifically,
+look for the download button in:
+
+- the main project's page
+- the branches page
+- the tags page
+
+If the latest build has failed to upload the artifacts, you can see that
+information in the UI.

+# Cycle Analytics
+
+> [Introduced][ce-5986] in GitLab 8.12.
+>
+> **Note:**
+This the first iteration of Cycle Analytics, you can follow the following issue
+to track the changes that are coming to this feature: [#20975][ce-20975].
+
+Cycle Analytics measures the time it takes to go from [an idea to production] for
+each project you have. This is achieved by not only indicating the total time it
+takes to reach at that point, but the total time is broken down into the
+multiple stages an idea has to pass through to be shipped.
+
+Cycle Analytics is that it is tightly coupled with the [GitLab flow] and
+calculates a separate median for each stage.
+
+## Overview
+
+You can find the Cycle Analytics page under your project's **Pipelines > Cycle
+Analytics** tab.
+
+![Cycle Analytics landing page](img/cycle_analytics_landing_page.png)
+
+You can see that there are seven stages in total:
+
+- **Issue** (Tracker)
+    - Median time from issue creation until given a milestone or list label
+      (first assignment, any milestone, milestone date or assignee is not required)
+- **Plan** (Board)
+    - Median time from giving an issue a milestone or label until pushing the
+      first commit
+- **Code** (IDE)
+    - Median time from the first commit until the merge request is created
+- **Test** (CI)
+    - Median total test time for all commits/merges
+- **Review** (Merge Request/MR)
+    - Median time from merge request creation until the merge request is merged
+      (closed merge requests won't be taken into account)
+- **Staging** (Continuous Deployment)
+    - Median time from when the merge request got merged until the deploy to
+      production (production is last stage/environment)
+- **Production** (Total)
+   - Sum of all the above stages excluding the Test (CI) time
+
+## How the data is measured
+
+Cycle Analytics records cycle time so only data on the issues that have been
+deployed to production are measured. In case you just started a new project and
+you have not pushed anything to production, then you will not be able to
+properly see the Cycle Analytics of your project.
+
+Specifically, if your CI is not set up and you have not defined a `production`
+[environment], then you will not have any data.
+
+Below you can see in more detail what the various stages of Cycle Analytics mean.
+
+| **Stage** | **Description** |
+| --------- | --------------- |
+| Issue     | Measures the median time between creating an issue and taking action to solve it, by either labeling it or adding it to a milestone, whatever comes first. The label will be tracked only if it already has an [Issue Board list][board] created for it. |
+| Plan      | Measures the median time between the action you took for the previous stage, and pushing the first commit to the repository. To make this change tracked, the pushed commit needs to contain the [issue closing pattern], for example `Closes #xxx`, where `xxx` is the number of the issue related to this commit. If the commit does not contain the issue closing pattern, it is not considered to the measurement time of the stage. |
+| Code      | Measures the median time between pushing a first commit (previous stage) and creating a merge request related to that commit. The key to keep the process tracked is include the [issue closing pattern] to the description of the merge request. |
+| Test      | Measures the median time to run the entire pipeline for that project. It's related to the time GitLab CI takes to run every job for the commits pushed to that merge request defined in the previous stage. It is basically the start->finish time for all pipelines. `master` is not excluded. It does not attempt to track time for any particular stages. |
+| Review    | Measures the median time taken to review the merge request, between its creation and until it's merged. |
+| Staging   | Measures the median time between merging the merge request until the very first deployment to production. It's tracked by the [environment] set to `production` in your GitLab CI configuration. If there isn't a `production` environment, this is not tracked. |
+| Production| The sum of all time taken to run the entire process, from issue creation to deploying the code to production. |
+
+---
+
+Here's a little explanation of how this works behind the scenes:
+
+1. Issues and merge requests are grouped together in pairs, such that for each
+   `<issue, merge request>` pair, the merge request has `Fixes #xxx` for the
+   corresponding issue. All other issues and merge requests are **not** considered.
+
+1. Then the <issue, merge request> pairs are filtered out. Any merge request
+   that has **not** been deployed to production in the last XX days (specified
+   by the UI - default is 90 days) prohibits these pairs from being considered.
+
+1. For the remaining `<issue, merge request>` pairs, we check the information that
+   we need for the stages, like issue creation date, merge request merge time,
+   etc.
+
+To sum up, anything that doesn't follow the [GitLab flow] won't be tracked at all.
+So, if a merge request doesn't close an issue or an issue is not labeled with a
+label present in the Issue Board or assigned a milestone or a project has no
+`production` environment, the Cycle Analytics dashboard won't present any data
+at all.
+
+## Permissions
+
+The current permissions on the Cycle Analytics dashboard are:
+
+- Public projects - anyone can access
+- Private/internal projects - any member (guest level and above) can access

+# Description templates
+
+>[Introduced][ce-4981] in GitLab 8.11.
+
+Description templates allow you to define context-specific templates for issue
+and merge request description fields for your project.
+
+## Overview
+
+By using the description templates, users that create a new issue or merge
+request can select a description template to help them communicate with other
+contributors effectively.
+
+Every GitLab project can define its own set of description templates as they
+are added to the root directory of a GitLab project's repository.
+
+Description templates must be written in [Markdown](../markdown.md) and stored
+in your project's repository under a directory named `.gitlab`. Only the
+templates of the default branch will be taken into account.
+
+## Creating issue templates
+
+Create a new Markdown (`.md`) file inside the `.gitlab/issue_templates/`
+directory in your repository. Commit and push to your default branch.
+
+## Creating merge request templates
+
+Similarly to issue templates, create a new Markdown (`.md`) file inside the
+`.gitlab/merge_request_templates/` directory in your repository. Commit and
+push to your default branch.
+
+## Using the templates
+
+Let's take for example that you've created the file `.gitlab/issue_templates/Bug.md`.
+This will enable the `Bug` dropdown option when creating or editing issues. When
+`Bug` is selected, the content from the `Bug.md` template file will be copied
+to the issue description field. The 'Reset template' button will discard any
+changes you made after picking the template and return it to its initial status.
+

+# Issue board
+
+> [Introduced][ce-5554] in GitLab 8.11.
+
+The GitLab Issue Board is a software project management tool used to plan,
+organize, and visualize a workflow for a feature or product release.
+It can be seen like a light version of a [Kanban] or a [Scrum] board.
+
+Other interesting links:
+
+- [GitLab Issue Board landing page on about.gitlab.com][landing]
+- [YouTube video introduction to Issue Boards][youtube]
+
+## Overview
+
+The Issue Board builds on GitLab's existing issue tracking functionality and
+leverages the power of [labels] by utilizing them as lists of the scrum board.
+
+With the Issue Board you can have a different view of your issues while also
+maintaining the same filtering and sorting abilities you see across the
+issue tracker.
+
+Below is a table of the definitions used for GitLab's Issue Board.
+
+| What we call it  | What it means |
+| --------------  | ------------- |
+| **Issue Board** | It represents a different view for your issues. It can have multiple lists with each list consisting of issues represented by cards. |
+| **List**        | Each label that exists in the issue tracker can have its own dedicated list. Every list is named after the label it is based on and is represented by a column which contains all the issues associated with that label. You can think of a list like the results you get when you filter the issues by a label in your issue tracker. |
+| **Card**        | Every card represents an issue and it is shown under the list for which it has a label. The information you can see on a card consists of the issue number, the issue title, the assignee and the labels associated with it. You can drag cards around from one list to another. Issues inside lists are [ordered by priority](labels.md#prioritize-labels). |
+
+There are three types of lists, the ones you create based on your labels, and
+two default:
+
+- **Backlog** (default): shows all opened issues that do not fall in one of the other lists. Always appears on the very left.
+- **Done** (default): shows all closed issues that do not fall in one of the other lists. Always appears on the very right.
+- Label list: a list based on a label. It shows all opened or closed issues with that label.
+
+![GitLab Issue Board](img/issue_board.png)
+
+---
+
+In short, here's a list of actions you can take in an Issue Board:
+
+- [Create a new list](#creating-a-new-list).
+- [Delete an existing list](#deleting-a-list).
+- Drag issues between lists.
+- Drag and reorder the lists themselves.
+- Change issue labels on-the-fly while dragging issues between lists.
+- Close an issue if you drag it to the **Done** list.
+- Create a new list from a non-existing label by [creating the label on-the-fly](#creating-a-new-list)
+  within the Issue Board.
+- [Filter issues](#filtering-issues) that appear across your Issue Board.
+
+If you are not able to perform one or more of the things above, make sure you
+have the right [permissions](#permissions).
+
+## First time using the Issue Board
+
+The first time you navigate to your Issue Board, you will be presented with the
+two default lists (**Backlog** and **Done**) and a welcoming message that gives
+you two options. You can either create a predefined set of labels and create
+their corresponding lists to the Issue Board or opt-out and use your own lists.
+
+![Issue Board welcome message](img/issue_board_welcome_message.png)
+
+If you choose to use and create the predefined lists, they will appear as empty
+because the labels associated to them will not exist up until that moment,
+which means the system has no way of populating them automatically. That's of
+course if the predefined labels don't already exist. If any of them does exist,
+the list will be created and filled with the issues that have that label.
+
+## Creating a new list
+
+Create a new list by clicking on the **Create new list** button at the upper
+right corner of the Issue Board.
+
+![Issue Board welcome message](img/issue_board_add_list.png)
+
+Simply choose the label to create the list from. The new list will be inserted
+at the end of the lists, before **Done**. Moving and reordering lists is as
+easy as dragging them around.
+
+To create a list for a label that doesn't yet exist, simply create the label by
+choosing **Create new label**. The label will be created on-the-fly and it will
+be immediately added to the dropdown. You can now choose it to create a list.
+
+## Deleting a list
+
+To delete a list from the Issue Board use the small trash icon that is present
+in the list's heading. A confirmation dialog will appear for you to confirm.
+
+Deleting a list doesn't have any effect in issues and labels, it's just the
+list view that is removed. You can always add it back later if you need.
+
+## Searching issues in the Backlog list
+
+The very first time you start using the Issue Board, it is very likely your
+issue tracker is already populated with labels and issues. In that case,
+**Backlog** will have all the issues that don't belong to another list, and
+**Done** will have all the closed ones.
+
+For performance and visibility reasons, each list shows the first 20 issues
+by default. If you have more than 20, you have to start scrolling down for the
+next 20 issues to appear. This can be cumbersome if your issue tracker hosts
+hundreds of issues, and for that reason it is easier to search for issues to
+move from **Backlog** to another list.
+
+Start typing in the search bar under the **Backlog** list and the relevant
+issues will appear.
+
+![Issue Board search Backlog](img/issue_board_search_backlog.png)
+
+## Filtering issues
+
+You should be able to use the filters on top of your Issue Board to show only
+the results you want. This is similar to the filtering used in the issue tracker
+since the metadata from the issues and labels are re-used in the Issue Board.
+
+You can filter by author, assignee, milestone and label.
+
+## Creating workflows
+
+By reordering your lists, you can create workflows. As lists in Issue Boards are
+based on labels, it works out of the box with your existing issues. So if you've
+already labeled things with 'Backend' and 'Frontend', the issue will appear in
+the lists as you create them. In addition, this means you can easily move
+something between lists by changing a label.
+
+A typical workflow of using the Issue Board would be:
+
+1. You have [created][create-labels] and [prioritized][label-priority] labels
+   so that you can easily categorize your issues.
+1. You have a bunch of issues (ideally labeled).
+1. You visit the Issue Board and start [creating lists](#creating-a-new-list) to
+   create a workflow.
+1. You move issues around in lists so that your team knows who should be working
+   on what issue.
+1. When the work by one team is done, the issue can be dragged to the next list
+   so someone else can pick up.
+1. When the issue is finally resolved, the issue is moved to the **Done** list
+   and gets automatically closed.
+
+For instance you can create a list based on the label of 'Frontend' and one for
+'Backend'. A designer can start working on an issue by dragging it from
+**Backlog** to 'Frontend'. That way, everyone knows that this issue is now being
+worked on by the designers. Then, once they're done, all they have to do is
+drag it over to the next list, 'Backend', where a backend developer can
+eventually pick it up. Once they’re done, they move it to **Done**, to close the
+issue.
+
+This process can be seen clearly when visiting an issue since with every move
+to another list the label changes and a system not is recorded.
+

+
+## Permissions
+
+[Developers and up](../permissions.md) can use all the functionality of the
+Issue Board, that is create/delete lists and drag issues around.
+
+## Tips
+
+A few things to remember:
+
+- The label that corresponds to a list is hidden for issues under that list.
+- Moving an issue between lists removes the label from the list it came from
+  and adds the label from the list it goes to.
+- When moving a card to **Done**, the label of the list it came from is removed
+  and the issue gets closed.
+- An issue can exist in multiple lists if it has more than one label.
+- Lists are populated with issues automatically if the issues are labeled.
+- Clicking on the issue title inside a card will take you to that issue.
+- Clicking on a label inside a card will quickly filter the entire Issue Board
+  and show only the issues from all lists that have that label.
+- Issues inside lists are [ordered by priority][label-priority].
+- For performance and visibility reasons, each list shows the first 20 issues
+  by default. If you have more than 20 issues start scrolling down and the next
+  20 will appear.

+# Automatic issue closing
+
+>**Note:**
+This is the user docs. In order to change the default issue closing pattern,
+follow the steps in the [administration docs].
+
+When a commit or merge request resolves one or more issues, it is possible to
+automatically have these issues closed when the commit or merge request lands
+in the project's default branch.
+
+If a commit message or merge request description contains a sentence matching
+a certain regular expression, all issues referenced from the matched text will
+be closed. This happens when the commit is pushed to a project's **default**
+branch, or when a commit or merge request is merged into it.
+
+## Default closing pattern value
+
+When not specified, the default issue closing pattern as shown below will be
+used:
+
+```bash
+((?:[Cc]los(?:e[sd]?|ing)|[Ff]ix(?:e[sd]|ing)?|[Rr]esolv(?:e[sd]?|ing))(:?) +(?:(?:issues? +)?%{issue_ref}(?:(?:, *| +and +)?)|([A-Z][A-Z0-9_]+-\d+))+)
+```
+
+Note that `%{issue_ref}` is a complex regular expression defined inside GitLab's
+source code that can match a reference to 1) a local issue (`#123`),
+2) a cross-project issue (`group/project#123`) or 3) a link to an issue
+(`https://gitlab.example.com/group/project/issues/123`).
+
+---
+
+This translates to the following keywords:
+
+- Close, Closes, Closed, Closing, close, closes, closed, closing
+- Fix, Fixes, Fixed, Fixing, fix, fixes, fixed, fixing
+- Resolve, Resolves, Resolved, Resolving, resolve, resolves, resolved, resolving
+
+---
+
+For example the following commit message:
+
+```
+Awesome commit message
+
+Fix #20, Fixes #21 and Closes group/otherproject#22.
+This commit is also related to #17 and fixes #18, #19
+and https://gitlab.example.com/group/otherproject/issues/23.
+```
+
+will close `#18`, `#19`, `#20`, and `#21` in the project this commit is pushed
+to, as well as `#22` and `#23` in group/otherproject. `#17` won't be closed as
+it does not match the pattern. It works with multi-line commit messages as well
+as one-liners when used with `git commit -m`.

+# Koding & GitLab
+
+> [Introduced][ce-5909] in GitLab 8.11.
+
+This document will guide you through using Koding integration on GitLab in
+detail. For configuring and installing please follow the
+[administrator guide](../../administration/integration/koding.md).
+
+You can use Koding integration to run and develop your projects on GitLab. This
+will allow you and the users to test your project without leaving the browser.
+Koding handles projects as stacks which are basic recipes to define your
+environment for your project. With this integration you can automatically
+create a proper stack template for your projects. Currently auto-generated
+stack templates are designed to work with AWS which requires a valid AWS
+credential to be able to use these stacks. You can find more information about
+stacks and the other providers that you can use on Koding following the
+[Koding documentation][koding-docs].
+
+## Enable Integration
+
+You can enable Koding integration by providing the running Koding instance URL
+in Application Settings under **Admin area > Settings** (`/admin/application_settings`).
+
+![Enable Koding](img/koding_enable-koding.png)
+
+Once enabled you will see `Koding` link on your sidebar which leads you to
+Koding Landing page.
+
+![Koding Landing](img/koding_landing.png)
+
+You can navigate to running Koding instance from here. For more information and
+details about configuring the integration, please follow the
+[administrator guide](../../administration/integration/koding.md).
+
+## Set up Koding on Projects
+
+Once it's enabled, you will see some integration buttons on Project pages,
+Merge Requests etc. To get started working on a specific project you first need
+to create a `.koding.yml` file under your project root. You can easily do that
+by using `Set Up Koding` button which will be visible on every project's
+landing page;
+
+![Set Up Koding](img/koding_set-up-ide.png)
+
+Once you click this will open a New File page on GitLab with auto-generated
+`.koding.yml` content based on your server and repository configuration.
+
+![Commit .koding.yml](img/koding_commit-koding.yml.png)
+
+
+## Run a project on Koding
+
+If there is `.koding.yml` exists in your project root, you will see
+`Run in IDE (Koding)` button in your project landing page. You can initiate the
+process from here.
+
+![Run on Koding](img/koding_run-in-ide.png)
+
+This will open Koding defined in the settings in a new window and will start
+importing the project's stack file.
+
+![Import Stack](img/koding_stack-import.png)
+
+You should see the details of your repository imported into your Koding
+instance. Once it's completed it will lead you to the Stack Editor and from
+there you can start using your new stack integrated with your project on your
+GitLab instance. For details about what's next you can follow
+[this guide](https://www.koding.com/docs/creating-an-aws-stack) from step 8.
+
+Once stack initialized you will see the `README.md` content from your project
+in `Stack Build` wizard, this wizard will let you build the stack and import
+your project into it. **Once it's completed it will automatically open the
+related vm instead of importing from scratch**.
+
+![Stack Building](img/koding_start-build.png)
+
+This will take time depending on the required environment.
+
+![Stack Building in Progress](img/koding_build-in-progress.png)
+
+It usually takes ~4 min. to make it ready with a `t2.nano` instance on given
+AWS region. (`t2.nano` is default vm type on auto-generated stack template
+which can be manually changed).
+
+![Stack Building Success](img/koding_build-success.png)
+
+You can check out the `Build Logs` from this success modal as well.
+
+![Stack Build Logs](img/koding_build-logs.png)
+
+You can now `Start Coding`!
+
+![Edit On IDE](img/koding_edit-on-ide.png)
+
+## Try a Merge Request on IDE
+
+It's also possible to try a change on IDE before merging it. This flow only
+enabled if the target project has `.koding.yml` in it's target branch. You
+should see the alternative version of `Run in IDE (Koding)` button in merge
+request pages as well;
+
+![Run in IDE on MR](img/koding_run-mr-in-ide.png)
+
+This will again take you to Koding with proper arguments passed, which will
+allow Koding to modify the stack template provided by target branch. You can
+see the difference;
+
+![Different Branch for MR](img/koding_different-stack-on-mr-try.png)
+
+The flow for the branch stack is also same with the regular project flow.
+
+## Open GitLab from Koding
+
+Since stacks generated with import flow defined in previous steps, they have
+information about the repository they are belonging to. By using this
+information you can access to related GitLab page from stacks on your sidebar
+on Koding.
+
+![Open GitLab from Koding](img/koding_open-gitlab-from-koding.png)

+# Merge Requests
+
+Merge requests allow you to exchange changes you made to source code and
+collaborate with other people on the same project.
+
+## Authorization for merge requests
+
+There are two main ways to have a merge request flow with GitLab:
+
+1. Working with [protected branches][] in a single repository
+1. Working with forks of an authoritative project
+
+[Learn more about the authorization for merge requests.](merge_requests/authorization_for_merge_requests.md)
+
+## Cherry-pick changes
+
+Cherry-pick any commit in the UI by simply clicking the **Cherry-pick** button
+in a merged merge requests or a commit.
+
+[Learn more about cherry-picking changes.](merge_requests/cherry_pick_changes.md)
+
+## Merge when build succeeds
+
+When reviewing a merge request that looks ready to merge but still has one or
+more CI builds running, you can set it to be merged automatically when all
+builds succeed. This way, you don't have to wait for the builds to finish and
+remember to merge the request manually.
+
+[Learn more about merging when build succeeds.](merge_requests/merge_when_build_succeeds.md)
+
+## Resolve discussion comments in merge requests reviews
+
+Keep track of the progress during a code review with resolving comments.
+Resolving comments prevents you from forgetting to address feedback and lets
+you hide discussions that are no longer relevant.
+
+[Read more about resolving discussion comments in merge requests reviews.](merge_requests/merge_request_discussion_resolution.md)
+
+## Resolve conflicts
+
+When a merge request has conflicts, GitLab may provide the option to resolve
+those conflicts in the GitLab UI.
+
+[Learn more about resolving merge conflicts in the UI.](merge_requests/resolve_conflicts.md)
+
+## Revert changes
+
+GitLab implements Git's powerful feature to revert any commit with introducing
+a **Revert** button in merge requests and commit details.
+
+[Learn more about reverting changes in the UI](merge_requests/revert_changes.md)
+
+## Merge requests versions
+
+Every time you push to a branch that is tied to a merge request, a new version
+of merge request diff is created. When you visit a merge request that contains
+more than one pushes, you can select and compare the versions of those merge
+request diffs.
+
+[Read more about the merge requests versions.](merge_requests/versions.md)
+
+## Work In Progress merge requests
+
+To prevent merge requests from accidentally being accepted before they're
+completely ready, GitLab blocks the "Accept" button for merge requests that
+have been marked as a **Work In Progress**.
+
+[Learn more about settings a merge request as "Work In Progress".](merge_requests/work_in_progress_merge_requests.md)
+
+## Ignore whitespace changes in Merge Request diff view
+
+If you click the **Hide whitespace changes** button, you can see the diff
+without whitespace changes (if there are any). This is also working when on a
+specific commit page.
+
+![MR diff](merge_requests/img/merge_request_diff.png)
+
+>**Tip:**
+You can append `?w=1` while on the diffs page of a merge request to ignore any
+whitespace changes.
+
+## Tips
+
+Here are some tips that will help you be more efficient with merge requests in
+the command line.
+
+> **Note:**
+This section might move in its own document in the future.
+
+### Checkout merge requests locally
+
+A merge request contains all the history from a repository, plus the additional
+commits added to the branch associated with the merge request. Here's a few
+tricks to checkout a merge request locally.
+
+Please note that you can checkout a merge request locally even if the source
+project is a fork (even a private fork) of the target project.
+
+#### Checkout locally by adding a git alias
+
+Add the following alias to your `~/.gitconfig`:
+
+```
+[alias]
+    mr = !sh -c 'git fetch $1 merge-requests/$2/head:mr-$1-$2 && git checkout mr-$1-$2' -
+```
+
+Now you can check out a particular merge request from any repository and any
+remote. For example, to check out the merge request with ID 5 as shown in GitLab
+from the `upstream` remote, do:
+
+```
+git mr upstream 5
+```
+
+This will fetch the merge request into a local `mr-upstream-5` branch and check
+it out.
+
+#### Checkout locally by modifying `.git/config` for a given repository
+
+Locate the section for your GitLab remote in the `.git/config` file. It looks
+like this:
+
+```
+[remote "origin"]
+  url = https://gitlab.com/gitlab-org/gitlab-ce.git
+  fetch = +refs/heads/*:refs/remotes/origin/*
+```
+
+You can open the file with:
+
+```
+git config -e
+```
+
+Now add the following line to the above section:
+
+```
+fetch = +refs/merge-requests/*/head:refs/remotes/origin/merge-requests/*
+```
+
+In the end, it should look like this:
+
+```
+[remote "origin"]
+  url = https://gitlab.com/gitlab-org/gitlab-ce.git
+  fetch = +refs/heads/*:refs/remotes/origin/*
+  fetch = +refs/merge-requests/*/head:refs/remotes/origin/merge-requests/*
+```
+
+Now you can fetch all the merge requests:
+
+```
+git fetch origin
+
+...
+From https://gitlab.com/gitlab-org/gitlab-ce.git
+ * [new ref]         refs/merge-requests/1/head -> origin/merge-requests/1
+ * [new ref]         refs/merge-requests/2/head -> origin/merge-requests/2
+...
+```
+
+And to check out a particular merge request:
+
+```
+git checkout origin/merge-requests/1
+```

+# Authorization for Merge requests
+
+There are two main ways to have a merge request flow with GitLab:
+
+1. Working with [protected branches] in a single repository.
+1. Working with forks of an authoritative project.
+
+## Protected branch flow
+
+With the protected branch flow everybody works within the same GitLab project.
+
+The project maintainers get Master access and the regular developers get
+Developer access.
+
+The maintainers mark the authoritative branches as 'Protected'.
+
+The developers push feature branches to the project and create merge requests
+to have their feature branches reviewed and merged into one of the protected
+branches.
+
+By default, only users with Master access can merge changes into a protected
+branch.
+
+**Advantages**
+
+- Fewer projects means less clutter.
+- Developers need to consider only one remote repository.
+
+**Disadvantages**
+
+- Manual setup of protected branch required for each new project
+
+## Forking workflow
+
+With the forking workflow the maintainers get Master access and the regular
+developers get Reporter access to the authoritative repository, which prohibits
+them from pushing any changes to it.
+
+Developers create forks of the authoritative project and push their feature
+branches to their own forks.
+
+To get their changes into master they need to create a merge request across
+forks.
+
+**Advantages**
+
+- In an appropriately configured GitLab group, new projects automatically get
+  the required access restrictions for regular developers: fewer manual steps
+  to configure authorization for new projects.
+
+**Disadvantages**
+
+- The project need to keep their forks up to date, which requires more advanced
+  Git skills (managing multiple remotes).

+# Cherry-pick changes
+
+> [Introduced][ce-3514] in GitLab 8.7.
+
+---
+
+GitLab implements Git's powerful feature to [cherry-pick any commit][git-cherry-pick]
+with introducing a **Cherry-pick** button in Merge Requests and commit details.
+
+## Cherry-picking a Merge Request
+
+After the Merge Request has been merged, a **Cherry-pick** button will be available
+to cherry-pick the changes introduced by that Merge Request:
+
+![Cherry-pick Merge Request](img/cherry_pick_changes_mr.png)
+
+---
+
+You can cherry-pick the changes directly into the selected branch or you can opt to
+create a new Merge Request with the cherry-pick changes:
+
+![Cherry-pick Merge Request modal](img/cherry_pick_changes_mr_modal.png)
+
+## Cherry-picking a Commit
+
+You can cherry-pick a Commit from the Commit details page:
+
+![Cherry-pick commit](img/cherry_pick_changes_commit.png)
+
+---
+
+Similar to cherry-picking a Merge Request, you can opt to cherry-pick the changes
+directly into the target branch or create a new Merge Request to cherry-pick the
+changes:
+
+![Cherry-pick commit modal](img/cherry_pick_changes_commit_modal.png)
+
+---
+
+Please note that when cherry-picking merge commits, the mainline will always be the
+first parent. If you want to use a different mainline then you need to do that
+from the command line.
+
+Here is a quick example to cherry-pick a merge commit using the second parent as the
+mainline:
+
+```bash
+git cherry-pick -m 2 7a39eb0
+```

+Discussion resolution helps keep track of progress during code review.
+Resolving comments prevents you from forgetting to address feedback and lets you
+hide discussions that are no longer relevant.
+
+!["A discussion between two people on a piece of code"][discussion-view]
+
+Comments and discussions can be resolved by anyone with at least Developer
+access to the project, as well as by the author of the merge request.
+
+## Marking a comment or discussion as resolved
+
+You can mark a discussion as resolved by clicking the "Resolve discussion"

+# Merge When Build Succeeds
+
+When reviewing a merge request that looks ready to merge but still has one or
+more CI builds running, you can set it to be merged automatically when all
+builds succeed. This way, you don't have to wait for the builds to finish and
+remember to merge the request manually.
+
+![Enable](img/merge_when_build_succeeds_enable.png)
+
+When you hit the "Merge When Build Succeeds" button, the status of the merge
+request will be updated to represent the impending merge. If you cannot wait
+for the build to succeed and want to merge immediately, this option is available
+in the dropdown menu on the right of the main button.
+
+Both team developers and the author of the merge request have the option to
+cancel the automatic merge if they find a reason why it shouldn't be merged
+after all.
+
+![Status](img/merge_when_build_succeeds_status.png)
+
+When the build succeeds, the merge request will automatically be merged. When
+the build fails, the author gets a chance to retry any failed builds, or to
+push new commits to fix the failure.
+
+When the builds are retried and succeed on the second try, the merge request
+will automatically be merged after all. When the merge request is updated with
+new commits, the automatic merge is automatically canceled to allow the new
+changes to be reviewed.
+
+## Only allow merge requests to be merged if the build succeeds
+
+> **Note:**
+You need to have builds configured to enable this feature.
+
+You can prevent merge requests from being merged if their build did not succeed.
+
+Navigate to your project's settings page, select the
+**Only allow merge requests to be merged if the build succeeds** check box and
+hit **Save** for the changes to take effect.
+
+![Only allow merge if build succeeds settings](img/merge_when_build_succeeds_only_if_succeeds_settings.png)
+
+From now on, every time the build fails you will not be able to merge the merge
+request from the UI, until you make the build pass.

+# Merge conflict resolution
+
+> [Introduced][ce-5479] in GitLab 8.11.
+
+When a merge request has conflicts, GitLab may provide the option to resolve
+those conflicts in the GitLab UI. (See
+[conflicts available for resolution](#conflicts-available-for-resolution) for
+more information on when this is available.) If this is an option, you will see
+a **resolve these conflicts** link in the merge request widget:
+
+![Merge request widget](img/merge_request_widget.png)
+
+Clicking this will show a list of files with conflicts, with conflict sections
+highlighted:
+
+![Conflict section](img/conflict_section.png)
+
+Once all conflicts have been marked as using 'ours' or 'theirs', the conflict
+can be resolved. This will perform a merge of the target branch of the merge
+request into the source branch, resolving the conflicts using the options
+chosen. If the source branch is `feature` and the target branch is `master`,
+this is similar to performing `git checkout feature; git merge master` locally.
+
+## Conflicts available for resolution
+
+GitLab allows resolving conflicts in a file where all of the below are true:
+
+- The file is text, not binary
+- The file is in a UTF-8 compatible encoding
+- The file does not already contain conflict markers
+- The file, with conflict markers added, is not over 200 KB in size
+- The file exists under the same path in both branches
+
+If any file with conflicts in that merge request does not meet all of these
+criteria, the conflicts for that merge request cannot be resolved in the UI.
+
+Additionally, GitLab does not detect conflicts in renames away from a path. For
+example, this will not create a conflict: on branch `a`, doing `git mv file1
+file2`; on branch `b`, doing `git mv file1 file3`. Instead, both files will be
+present in the branch after the merge request is merged.

+# Reverting changes
+
+> [Introduced][ce-1990] in GitLab 8.5.
+
+---
+
+GitLab implements Git's powerful feature to [revert any commit][git-revert]
+with introducing a **Revert** button in Merge Requests and commit details.
+
+## Reverting a Merge Request
+
+_**Note:** The **Revert** button will only be available for Merge Requests
+created since GitLab 8.5. However, you can still revert a Merge Request
+by reverting the merge commit from the list of Commits page._
+
+After the Merge Request has been merged, a **Revert** button will be available
+to revert the changes introduced by that Merge Request:
+
+![Revert Merge Request](img/revert_changes_mr.png)
+
+---
+
+You can revert the changes directly into the selected branch or you can opt to
+create a new Merge Request with the revert changes:
+
+![Revert Merge Request modal](img/revert_changes_mr_modal.png)
+
+---
+
+After the Merge Request has been reverted, the **Revert** button will not be
+available anymore.
+
+## Reverting a Commit
+
+You can revert a Commit from the Commit details page:
+
+![Revert commit](img/revert_changes_commit.png)
+
+---
+
+Similar to reverting a Merge Request, you can opt to revert the changes
+directly into the target branch or create a new Merge Request to revert the
+changes:
+
+![Revert commit modal](img/revert_changes_commit_modal.png)
+
+---
+
+After the Commit has been reverted, the **Revert** button will not be available
+anymore.
+
+Please note that when reverting merge commits, the mainline will always be the
+first parent. If you want to use a different mainline then you need to do that
+from the command line.
+
+Here is a quick example to revert a merge commit using the second parent as the
+mainline:
+
+```bash
+git revert -m 2 7a39eb0
+```

+Every time you push to a branch that is tied to a merge request, a new version
+of merge request diff is created. When you visit a merge request that contains
+more than one pushes, you can select and compare the versions of those merge
+request diffs.
+
+![Merge Request Versions](img/versions.png)
+
+By default, the latest version of changes is shown. However, you

+
+Please note that comments are disabled while viewing outdated merge versions
+or comparing to versions other than base.
+
+---
+
+>**Note:**
+Merge request versions are based on push not on commit. So, if you pushed 5
+commits in a single push, it will be a single option in the dropdown. If you
+pushed 5 times, that will count for 5 options.

+# New CI build permissions model
+
+> Introduced in GitLab 8.12.
+
+GitLab 8.12 has a completely redesigned [build permissions] system. You can find
+all discussion and all our concerns when choosing the current approach in issue
+[#18994](https://gitlab.com/gitlab-org/gitlab-ce/issues/18994).
+
+---
+
+Builds permissions should be tightly integrated with the permissions of a user
+who is triggering a build.
+
+The reasons to do it like that are:
+
+- We already have a permissions system in place: group and project membership
+  of users.
+- We already fully know who is triggering a build (using `git push`, using the
+  web UI, executing triggers).
+- We already know what user is allowed to do.
+- We use the user permissions for builds that are triggered by the user.
+- It opens a lot of possibilities to further enforce user permissions, like
+  allowing only specific users to access runners or use secure variables and
+  environments.
+- It is simple and convenient that your build can access everything that you
+  as a user have access to.
+- Short living unique tokens are now used, granting access for time of the build
+  and maximizing security.
+
+With the new behavior, any build that is triggered by the user, is also marked
+with their permissions. When a user does a `git push` or changes files through
+the web UI, a new pipeline will be usually created. This pipeline will be marked
+as created be the pusher (local push or via the UI) and any build created in this
+pipeline will have the permissions of the pusher.
+
+This allows us to make it really easy to evaluate the access for all projects
+that have Git submodules or are using container images that the pusher would
+have access too. **The permission is granted only for time that build is running.
+The access is revoked after the build is finished.**
+
+## Types of users
+
+It is important to note that we have a few types of users:
+
+- **Administrators**: CI builds created by Administrators will not have access
+  to all GitLab projects, but only to projects and container images of projects
+  that the administrator is a member of.That means that if a project is either
+  public or internal users have access anyway, but if a project is private, the
+  Administrator will have to be a member of it in order to have access to it
+  via another project's build.
+
+- **External users**: CI builds created by [external users][ext] will have
+  access only to projects to which user has at least reporter access. This
+  rules out accessing all internal projects by default,
+
+This allows us to make the CI and permission system more trustworthy.
+Let's consider the following scenario:
+
+1. You are an employee of a company. Your company has a number of internal tools
+   hosted in private repositories and you have multiple CI builds that make use
+   of these repositories.
+
+2. You invite a new [external user][ext]. CI builds created by that user do not
+   have access to internal repositories, because the user also doesn't have the
+   access from within GitLab. You as an employee have to grant explicit access
+   for this user. This allows us to prevent from accidental data leakage.
+
+## Build token
+
+A unique build token is generated for each build and it allows the user to
+access all projects that would be normally accessible to the user creating that
+build.
+
+We try to make sure that this token doesn't leak by:
+
+1. Securing all API endpoints to not expose the build token.
+1. Masking the build token from build logs.
+1. Allowing to use the build token **only** when build is running.
+
+However, this brings a question about the Runners security. To make sure that
+this token doesn't leak, you should also make sure that you configure
+your Runners in the most possible secure way, by avoiding the following:
+
+1. Any usage of Docker's `privileged` mode is risky if the machines are re-used.
+1. Using the `shell` executor since builds run on the same machine.
+
+By using an insecure GitLab Runner configuration, you allow the rogue developers
+to steal the tokens of other builds.
+
+## Debugging problems
+
+With the new permission model in place, there may be times that your build will
+fail. This is most likely because your project tries to access other project's
+sources, and you don't have the appropriate permissions. In the build log look
+for information about 403 or forbidden access messages
+
+As an Administrator, you can verify that the user is a member of the group or
+project they're trying to have access to, and you can impersonate the user to
+retry the failing build in order to verify that everything is correct.
+
+## Build triggers
+
+[Build triggers][triggers] do not support the new permission model.
+They continue to use the old authentication mechanism where the CI build
+can access only its own sources. We plan to remove that limitation in one of
+the upcoming releases.
+
+## Before GitLab 8.12
+
+In versions before GitLab 8.12, all CI builds would use the CI Runner's token
+to checkout project sources.
+
+The project's Runner's token was a token that you could find under the
+project's **Settings > CI/CD Pipelines** and was limited to access only that
+project.
+It could be used for registering new specific Runners assigned to the project
+and to checkout project sources.
+It could also be used with the GitLab Container Registry for that project,
+allowing pulling and pushing Docker images from within the CI build.
+
+---
+
+GitLab would create a special checkout URL like:
+
+```
+https://gitlab-ci-token:<project-runners-token>/gitlab.com/gitlab-org/gitlab-ce.git
+```
+
+And then the users could also use it in their CI builds all Docker related
+commands to interact with GitLab Container Registry. For example:
+
+```
+docker login -u gitlab-ci-token -p $CI_BUILD_TOKEN registry.gitlab.com
+```
+
+Using single token had multiple security implications:
+
+- The token would be readable to anyone who had developer access to a project
+  that could run CI builds, allowing the developer to register any specific
+  Runner for that project.
+- The token would allow to access only the project's sources, forbidding from
+  accessing any other projects.
+- The token was not expiring and was multi-purpose: used for checking out sources,
+  for registering specific runners and for accessing a project's container
+  registry with read-write permissions.
+
+All the above led to a new permission model for builds that was introduced
+with GitLab 8.12.
+
+## Making use of the new CI build permissions model
+
+With the new build permission model, there is now an easy way to access all
+dependent source code in a project. That way, we can:
+
+1. Access a project's Git submodules
+1. Access private container images
+1. Access project's and submodule LFS objects
+
+Let's see how that works with Git submodules and private Docker images hosted on
+the container registry.
+
+## Git submodules
+
+>
+It often happens that while working on one project, you need to use another
+project from within it; perhaps it’s a library that a third party developed or
+you’re developing a project separately and are using it in multiple parent
+projects.
+A common issue arises in these scenarios: you want to be able to treat the two
+projects as separate yet still be able to use one from within the other.
+>
+_Excerpt from the [Git website][git-scm] about submodules._
+
+If dealing with submodules, your project will probably have a file named
+`.gitmodules`. And this is how it usually looks like:
+
+```
+[submodule "tools"]
+	path = tools
+	url = git@gitlab.com/group/tools.git
+```
+
+> **Note:**
+If you are **not** using GitLab 8.12 or higher, you would need to work your way
+around this issue in order to access the sources of `gitlab.com/group/tools`
+(e.g., use [SSH keys](../ssh_keys/README.md)).
+>
+With GitLab 8.12 onward, your permissions are used to evaluate what a CI build
+can access. More information about how this system works can be found in the
+[Build permissions model](../../user/permissions.md#builds-permissions).
+
+To make use of the new changes, you have to update your `.gitmodules` file to
+use a relative URL.
+
+Let's consider the following example:
+
+1. Your project is located at `https://gitlab.com/secret-group/my-project`.
+1. To checkout your sources you usually use an SSH address like
+   `git@gitlab.com:secret-group/my-project.git`.
+1. Your project depends on `https://gitlab.com/group/tools`.
+1. You have the `.gitmodules` file with above content.
+
+Since Git allows the usage of relative URLs for your `.gitmodules` configuration,
+this easily allows you to use HTTP for cloning all your CI builds and SSH
+for all your local checkouts.
+
+For example, if you change the `url` of your `tools` dependency, from
+`git@gitlab.com/group/tools.git` to `../../group/tools.git`, this will instruct
+Git to automatically deduce the URL that should be used when cloning sources.
+Whether you use HTTP or SSH, Git will use that same channel and it will allow
+to make all your CI builds use HTTPS (because GitLab CI uses HTTPS for cloning
+your sources), and all your local clones will continue using SSH.
+
+Given the above explanation, your `.gitmodules` file should eventually look
+like this:
+
+```
+[submodule "tools"]
+	path = tools
+	url = ../../group/tools.git
+```
+
+However, you have to explicitly tell GitLab CI to clone your submodules as this
+is not done automatically. You can achieve that by adding a `before_script`
+section to your `.gitlab-ci.yml`:
+
+```
+before_script:
+  - git submodule update --init --recursive
+
+test:
+  script:
+    - run-my-tests
+```
+
+This will make GitLab CI initialize (fetch) and update (checkout) all your
+submodules recursively.
+
+In case your environment or your Docker image doesn't have Git installed,
+you have to either ask your Administrator or install the missing dependency
+yourself:
+
+```
+# Debian / Ubuntu
+before_script:
+  - apt-get update -y
+  - apt-get install -y git-core
+  - git submodule update --init --recursive
+
+# CentOS / RedHat
+before_script:
+  - yum install git
+  - git submodule update --init --recursive
+
+# Alpine
+before_script:
+  - apk add -U git
+  - git submodule update --init --recursive
+```
+
+### Container Registry
+
+With the update permission model we also extended the support for accessing
+Container Registries for private projects.
+
+> **Note:**
+As GitLab Runner 1.6 doesn't yet incorporate the introduced changes for
+permissions, this makes the `image:` directive to not work with private projects
+automatically. The manual configuration by an Administrator is required to use
+private images. We plan to remove that limitation in one of the upcoming releases.
+
+Your builds can access all container images that you would normally have access
+to. The only implication is that you can push to the Container Registry of the
+project for which the build is triggered.
+
+This is how an example usage can look like:
+
+```
+test:
+  script:
+    - docker login -u gitlab-ci-token -p $CI_BUILD_TOKEN $CI_REGISTRY
+    - docker pull $CI_REGISTRY/group/other-project:latest
+    - docker run $CI_REGISTRY/group/other-project:latest
+```

+## Using the Allowed to merge and Allowed to push settings
+
+> [Introduced][ce-5081] in GitLab 8.11.
+
+Since GitLab 8.11, we added another layer of branch protection which provides
+more granular management of protected branches. The "Developers can push"
+option was replaced by an "Allowed to push" setting which can be set to
+allow/prohibit Masters and/or Developers to push to a protected branch.
+
+Using the "Allowed to push" and "Allowed to merge" settings, you can control
+the actions that different roles can perform with the protected branch.
+For example, you could set "Allowed to push" to "No one", and "Allowed to merge"
+to "Developers + Masters", to require _everyone_ to submit a merge request for
+changes going into the protected branch. This is compatible with workflows like
+the [GitLab workflow](../../workflow/gitlab_flow.md).
+
+However, there are workflows where that is not needed, and only protecting from
+force pushes and branch removal is useful. For those workflows, you can allow
+everyone with write access to push to a protected branch by setting
+"Allowed to push" to "Developers + Masters".
+
+You can set the "Allowed to push" and "Allowed to merge" options while creating
+a protected branch or afterwards by selecting the option you want from the
+dropdown list in the "Already protected" area.
 
-Since GitLab 8.10, we added another layer of branch protection which provides

+# GitLab Web Editor
+
+Sometimes it's easier to make quick changes directly from the GitLab interface
+than to clone the project and use the Git command line tool. In this feature
+highlight we look at how you can create a new file, directory, branch or
+tag from the file browser. All of these actions are available from a single
+dropdown menu.
+
+## Create a file
+
+From a project's files page, click the '+' button to the right of the branch selector.
+Choose **New file** from the dropdown.
+
+![New file dropdown menu](img/web_editor_new_file_dropdown.png)
+
+---
+
+Enter a file name in the **File name** box. Then, add file content in the editor
+area. Add a descriptive commit message and choose a branch. The branch field
+will default to the branch you were viewing in the file browser. If you enter
+a new branch name, a checkbox will appear allowing you to start a new merge
+request after you commit the changes.
+
+When you are satisfied with your new file, click **Commit Changes** at the bottom.
+
+![Create file editor](img/web_editor_new_file_editor.png)
+
+### Template dropdowns
+
+When starting a new project, there are some common files which the new project
+might need too. Therefore a message will be displayed by GitLab to make this
+easy for you.
+
+![First file for your project](img/web_editor_template_dropdown_first_file.png)
+
+When clicking on either `LICENSE` or `.gitignore`, a dropdown will be displayed
+to provide you with a template which might be suitable for your project.
+
+![MIT license selected](img/web_editor_template_dropdown_mit_license.png)
+
+The license, changelog, contribution guide, or `.gitlab-ci.yml` file could also
+be added through a button on the project page. In the example below the license
+has already been created, which creates a link to the license itself.
+
+![New file button](img/web_editor_template_dropdown_buttons.png)
+
+>**Note:**
+The **Set up CI** button will not appear on an empty repository. You have to at
+least add a file in order for the button to show up.
+
+## Upload a file
+
+The ability to create a file is great when the content is text. However, this
+doesn't work well for binary data such as images, PDFs or other file types. In
+this case you need to upload a file.
+
+From a project's files page, click the '+' button to the right of the branch
+selector. Choose **Upload file** from the dropdown.
+
+![Upload file dropdown menu](img/web_editor_upload_file_dropdown.png)
+
+---
+
+Once the upload dialog pops up there are two ways to upload your file. Either
+drag and drop a file on the pop up or use the **click to upload** link. A file
+preview will appear once you have selected a file to upload.
+
+Enter a commit message, choose a branch, and click **Upload file** when you are
+ready.
+
+![Upload file dialog](img/web_editor_upload_file_dialog.png)
+
+## Create a directory
+
+To keep files in the repository organized it is often helpful to create a new
+directory.
+
+From a project's files page, click the '+' button to the right of the branch selector.
+Choose **New directory** from the dropdown.
+
+![New directory dropdown](img/web_editor_new_directory_dropdown.png)
+
+---
+
+In the new directory dialog enter a directory name, a commit message and choose
+the target branch. Click **Create directory** to finish.
+
+![New directory dialog](img/web_editor_new_directory_dialog.png)
+
+## Create a new branch
+
+There are multiple ways to create a branch from GitLab's web interface.
+
+### Create a new branch from an issue
+
+> [Introduced][ce-2808] in GitLab 8.6.
+
+In case your development workflow dictates to have an issue for every merge
+request, you can quickly create a branch right on the issue page which will be
+tied with the issue itself. You can see a **New Branch** button after the issue
+description, unless there is already a branch with the same name or a referenced
+merge request.
+
+![New Branch Button](img/new_branch_from_issue.png)
+
+Once you click it, a new branch will be created that diverges from the default
+branch of your project, by default `master`. The branch name will be based on
+the title of the issue and as suffix it will have its ID. Thus, the example
+screenshot above will yield a branch named
+`2-et-cum-et-sed-expedita-repellat-consequatur-ut-assumenda-numquam-rerum`.
+
+After the branch is created, you can edit files in the repository to fix
+the issue. When a merge request is created based on the newly created branch,
+the description field will automatically display the [issue closing pattern]
+`Closes #ID`, where `ID` the ID of the issue. This will close the issue once the
+merge request is merged.
+
+### Create a new branch from a project's dashboard
+
+If you want to make changes to several files before creating a new merge
+request, you can create a new branch up front. From a project's files page,
+choose **New branch** from the dropdown.
+
+![New branch dropdown](img/web_editor_new_branch_dropdown.png)
+
+---
+
+Enter a new **Branch name**. Optionally, change the **Create from** field
+to choose which branch, tag or commit SHA this new branch will originate from.
+This field will autocomplete if you start typing an existing branch or tag.
+Click **Create branch** and you will be returned to the file browser on this new
+branch.
+
+![New branch page](img/web_editor_new_branch_page.png)
+
+---
+
+You can now make changes to any files, as needed. When you're ready to merge
+the changes back to master you can use the widget at the top of the screen.
+This widget only appears for a period of time after you create the branch or
+modify files.
+
+![New push widget](img/web_editor_new_push_widget.png)
+
+## Create a new tag
+
+Tags are useful for marking major milestones such as production releases,
+release candidates, and more. You can create a tag from a branch or a commit
+SHA. From a project's files page, choose **New tag** from the dropdown.
+
+![New tag dropdown](img/web_editor_new_tag_dropdown.png)
+
+---
+
+Give the tag a name such as `v1.0.0`. Choose the branch or SHA from which you
+would like to create this new tag. You can optionally add a message and
+release notes. The release notes section supports markdown format and you can
+also upload an attachment. Click **Create tag** and you will be taken to the tag
+list page.
+
+![New tag page](img/web_editor_new_tag_page.png)
+
+## Tips
+
+When creating or uploading a new file, or creating a new directory, you can
+trigger a new merge request rather than committing directly to master. Enter
+a new branch name in the **Target branch** field. You will notice a checkbox
+appear that is labeled **Start a new merge request with these changes**. After
+you commit the changes you will be taken to a new merge request form.
+

-# Authorization for Merge requests
-
-There are two main ways to have a merge request flow with GitLab: working with protected branches in a single repository, or working with forks of an authoritative project.
-
-## Protected branch flow
-
-With the protected branch flow everybody works within the same GitLab project.
-
-The project maintainers get Master access and the regular developers get Developer access.
-
-The maintainers mark the authoritative branches as 'Protected'.
-
-The developers push feature branches to the project and create merge requests to have their feature branches reviewed and merged into one of the protected branches.
-
-Only users with Master access can merge changes into a protected branch.
-
-### Advantages
-
-- fewer projects means less clutter
-- developers need to consider only one remote repository
-
-### Disadvantages
-
-- manual setup of protected branch required for each new project
-
-## Forking workflow
-
-With the forking workflow the maintainers get Master access and the regular developers get Reporter access to the authoritative repository, which prohibits them from pushing any changes to it.
-
-Developers create forks of the authoritative project and push their feature branches to their own forks.
-
-To get their changes into master they need to create a merge request across forks.
-
-### Advantages
-
-- in an appropriately configured GitLab group, new projects automatically get the required access restrictions for regular developers: fewer manual steps to configure authorization for new projects
-
-### Disadvantages
-
-- the project need to keep their forks up to date, which requires more advanced Git skills (managing multiple remotes)

 # Import your project from GitHub to GitLab

 

+Import your projects from GitHub to GitLab with minimal effort.

+

+## Overview

+

 >**Note:**

-In order to enable the GitHub import setting, you may also want to

-enable the [GitHub integration][gh-import] in your GitLab instance. This

-configuration is optional, you will be able import your GitHub repositories

-with a Personal Access Token.

+If you are an administrator you can enable the [GitHub integration][gh-import]

+in your GitLab instance sitewide. This configuration is optional, users will be

+able import their GitHub repositories with a [personal access token][gh-token].

+

+- At its current state, GitHub importer can import:

+  - the repository description (GitLab 7.7+)

+  - the Git repository data (GitLab 7.7+)

+  - the issues (GitLab 7.7+)

+  - the pull requests (GitLab 8.4+)

+  - the wiki pages (GitLab 8.4+)

+  - the milestones (GitLab 8.7+)

+  - the labels (GitLab 8.7+)

+  - the release note descriptions (GitLab 8.12+)

+- References to pull requests and issues are preserved (GitLab 8.7+)

+- Repository public access is retained. If a repository is private in GitHub

+  it will be created as private in GitLab as well.

+

+## How it works

+

+When issues/pull requests are being imported, the GitHub importer tries to find

+the GitHub author/assignee in GitLab's database using the GitHub ID. For this

+to work, the GitHub author/assignee should have signed in beforehand in GitLab

+and [**associated their GitHub account**][social sign-in]. If the user is not

+found in GitLab's database, the project creator (most of the times the current

+user that started the import process) is set as the author, but a reference on

+the issue about the original GitHub author is kept.

+

+The importer will create any new namespaces (groups) if they don't exist or in

+the case the namespace is taken, the repository will be imported under the user's

+namespace that started the import process.

+

+## Importing your GitHub repositories

+

+The importer page is visible when you create a new project.

+

+![New project page on GitLab](img/import_projects_from_github_new_project_page.png)

 

-At its current state, GitHub importer can import:

+Click on the **GitHub** link and the import authorization process will start.

+There are two ways to authorize access to your GitHub repositories:

 

-- the repository description (introduced in GitLab 7.7)

-- the git repository data (introduced in GitLab 7.7)

-- the issues (introduced in GitLab 7.7)

-- the pull requests (introduced in GitLab 8.4)

-- the wiki pages (introduced in GitLab 8.4)

-- the milestones (introduced in GitLab 8.7)

-- the labels (introduced in GitLab 8.7)

+1. [Using the GitHub integration][gh-integration] (if it's enabled by your

+   GitLab administrator). This is the preferred way as it's possible to

+   preserve the GitHub authors/assignees. Read more in the [How it works](#how-it-works)

+   section.

+1. [Using a personal access token][gh-token] provided by GitHub.

 

-With GitLab 8.7+, references to pull requests and issues are preserved.

+![Select authentication method](img/import_projects_from_github_select_auth_method.png)

 

-It is not yet possible to import your cross-repository pull requests (those from

-forks). We are working on improving this in the near future.

+### Authorize access to your repositories using the GitHub integration

 

-The importer page is visible when you [create a new project][new-project].

-Click on the **GitHub** link and, if you are logged in via the GitHub

-integration, you will be redirected to GitHub for permission to access your

-projects. After accepting, you'll be automatically redirected to the importer.

+If the [GitHub integration][gh-import] is enabled by your GitLab administrator,

+you can use it instead of the personal access token.

+

+1. First you may want to connect your GitHub account to GitLab in order for

+   the username mapping to be correct. Follow the [social sign-in] documentation

+   on how to do so.

+1. Once you connect GitHub, click the **List your GitHub repositories** button

+   and you will be redirected to GitHub for permission to access your projects.

+1. After accepting, you'll be automatically redirected to the importer.

+

+You can now go on and [select which repositories to import](#select-which-repositories-to-import).

+

+### Authorize access to your repositories using a personal access token

+

+>**Note:**

+For a proper author/assignee mapping for issues and pull requests, the

+[GitHub integration][gh-integration] should be used instead of the

+[personal access token][gh-token]. If the GitHub integration is enabled by your

+GitLab administrator, it should be the preferred method to import your repositories.

+Read more in the [How it works](#how-it-works) section.

 

 If you are not using the GitHub integration, you can still perform a one-off

-authorization with GitHub to access your projects.

+authorization with GitHub to grant GitLab access your repositories:

 

-Alternatively, you can also enter a GitHub Personal Access Token. Once you enter

-your token, you'll be taken to the importer.

+1. Go to <https://github.com/settings/tokens/new>.

+1. Enter a token description.

+1. Check the `repo` scope.

+1. Click **Generate token**.

+1. Copy the token hash.

+1. Go back to GitLab and provide the token to the GitHub importer.

+1. Hit the **List your GitHub repositories** button and wait while GitLab reads

+   your repositories' information. Once done, you'll be taken to the importer

+   page to select the repositories to import.

+### Select which repositories to import

 

----

+After you've authorized access to your GitHub repositories, you will be

+redirected to the GitHub importer page.

+

+From there, you can see the import statuses of your GitHub repositories.

+

+- Those that are being imported will show a _started_ status,

+- those already successfully imported will be green with a _done_ status,

+- whereas those that are not yet imported will have an **Import** button on the

-# Reverting changes
-
-> [Introduced][ce-1990] in GitLab 8.5.
-
----
-
-GitLab implements Git's powerful feature to [revert any commit][git-revert]
-with introducing a **Revert** button in Merge Requests and commit details.
-
-## Reverting a Merge Request
-
-_**Note:** The **Revert** button will only be available for Merge Requests
-created since GitLab 8.5. However, you can still revert a Merge Request
-by reverting the merge commit from the list of Commits page._
-
-After the Merge Request has been merged, a **Revert** button will be available
-to revert the changes introduced by that Merge Request:
-
-![Revert Merge Request](img/revert_changes_mr.png)
-
----
-
-You can revert the changes directly into the selected branch or you can opt to
-create a new Merge Request with the revert changes:
-
-![Revert Merge Request modal](img/revert_changes_mr_modal.png)
-
----
-
-After the Merge Request has been reverted, the **Revert** button will not be
-available anymore.
-
-## Reverting a Commit
-
-You can revert a Commit from the Commit details page:
-
-![Revert commit](img/revert_changes_commit.png)

-
-Similar to reverting a Merge Request, you can opt to revert the changes
-directly into the target branch or create a new Merge Request to revert the
-changes:
-
-![Revert commit modal](img/revert_changes_commit_modal.png)
-
----
-
-After the Commit has been reverted, the **Revert** button will not be available
-anymore.
-
-Please note that when reverting merge commits, the mainline will always be the
-first parent. If you want to use a different mainline then you need to do that
-from the command line.
-
-Here is a quick example to revert a merge commit using the second parent as the
-mainline:

-```bash
-git revert -m 2 7a39eb0

-# GitLab Web Editor
-
-Sometimes it's easier to make quick changes directly from the GitLab interface
-than to clone the project and use the Git command line tool. In this feature
-highlight we look at how you can create a new file, directory, branch or
-tag from the file browser. All of these actions are available from a single
-dropdown menu.
-
-## Create a file
-
-From a project's files page, click the '+' button to the right of the branch selector.
-Choose **New file** from the dropdown.
-
-![New file dropdown menu](img/web_editor_new_file_dropdown.png)
-
----
-
-Enter a file name in the **File name** box. Then, add file content in the editor
-area. Add a descriptive commit message and choose a branch. The branch field
-will default to the branch you were viewing in the file browser. If you enter
-a new branch name, a checkbox will appear allowing you to start a new merge
-request after you commit the changes.
-
-When you are satisfied with your new file, click **Commit Changes** at the bottom.
-
-![Create file editor](img/web_editor_new_file_editor.png)
-
-## Upload a file
-
-The ability to create a file is great when the content is text. However, this
-doesn't work well for binary data such as images, PDFs or other file types. In
-this case you need to upload a file.
-
-From a project's files page, click the '+' button to the right of the branch
-selector. Choose **Upload file** from the dropdown.
-
-![Upload file dropdown menu](img/web_editor_upload_file_dropdown.png)
-
----
-
-Once the upload dialog pops up there are two ways to upload your file. Either
-drag and drop a file on the pop up or use the **click to upload** link. A file
-preview will appear once you have selected a file to upload.
-
-Enter a commit message, choose a branch, and click **Upload file** when you are
-ready.
-
-![Upload file dialog](img/web_editor_upload_file_dialog.png)
-
-## Create a directory
-
-To keep files in the repository organized it is often helpful to create a new
-directory.
-
-From a project's files page, click the '+' button to the right of the branch selector.
-Choose **New directory** from the dropdown.
-
-![New directory dropdown](img/web_editor_new_directory_dropdown.png)
-
----
-
-In the new directory dialog enter a directory name, a commit message and choose
-the target branch. Click **Create directory** to finish.
-
-![New directory dialog](img/web_editor_new_directory_dialog.png)
-
-## Create a new branch
-
-There are multiple ways to create a branch from GitLab's web interface.
-
-### Create a new branch from an issue
-
-> [Introduced][ce-2808] in GitLab 8.6.
-
-In case your development workflow dictates to have an issue for every merge
-request, you can quickly create a branch right on the issue page which will be
-tied with the issue itself. You can see a **New Branch** button after the issue
-description, unless there is already a branch with the same name or a referenced
-merge request.
-
-![New Branch Button](img/new_branch_from_issue.png)
-
-Once you click it, a new branch will be created that diverges from the default
-branch of your project, by default `master`. The branch name will be based on
-the title of the issue and as suffix it will have its ID. Thus, the example
-screenshot above will yield a branch named
-`2-et-cum-et-sed-expedita-repellat-consequatur-ut-assumenda-numquam-rerum`.
-
-After the branch is created, you can edit files in the repository to fix
-the issue. When a merge request is created based on the newly created branch,
-the description field will automatically display the [issue closing pattern]
-`Closes #ID`, where `ID` the ID of the issue. This will close the issue once the
-merge request is merged.
-
-### Create a new branch from a project's dashboard
-
-If you want to make changes to several files before creating a new merge
-request, you can create a new branch up front. From a project's files page,
-choose **New branch** from the dropdown.
-
-![New branch dropdown](img/web_editor_new_branch_dropdown.png)
-
----
-
-Enter a new **Branch name**. Optionally, change the **Create from** field
-to choose which branch, tag or commit SHA this new branch will originate from.
-This field will autocomplete if you start typing an existing branch or tag.
-Click **Create branch** and you will be returned to the file browser on this new
-branch.
-
-![New branch page](img/web_editor_new_branch_page.png)
-
----
-
-You can now make changes to any files, as needed. When you're ready to merge
-the changes back to master you can use the widget at the top of the screen.
-This widget only appears for a period of time after you create the branch or
-modify files.
-
-![New push widget](img/web_editor_new_push_widget.png)
-
-## Create a new tag
-
-Tags are useful for marking major milestones such as production releases,
-release candidates, and more. You can create a tag from a branch or a commit
-SHA. From a project's files page, choose **New tag** from the dropdown.
-
-![New tag dropdown](img/web_editor_new_tag_dropdown.png)
-
----
-
-Give the tag a name such as `v1.0.0`. Choose the branch or SHA from which you
-would like to create this new tag. You can optionally add a message and
-release notes. The release notes section supports markdown format and you can
-also upload an attachment. Click **Create tag** and you will be taken to the tag
-list page.
-
-![New tag page](img/web_editor_new_tag_page.png)
-
-## Tips
-
-When creating or uploading a new file, or creating a new directory, you can
-trigger a new merge request rather than committing directly to master. Enter
-a new branch name in the **Target branch** field. You will notice a checkbox
-appear that is labeled **Start a new merge request with these changes**. After
-you commit the changes you will be taken to a new merge request form.

+    # # Introduction - total running time
+    #
+    # The problem this module is trying to solve is finding the total running
+    # time amongst all the jobs, excluding retries and pending (queue) time.
+    # We could reduce this problem down to finding the union of periods.
+    #
+    # So each job would be represented as a `Period`, which consists of
+    # `Period#first` as when the job started and `Period#last` as when the
+    # job was finished. A simple example here would be:
+    #
+    # * A (1, 3)
+    # * B (2, 4)
+    # * C (6, 7)
+    #
+    # Here A begins from 1, and ends to 3. B begins from 2, and ends to 4.
+    # C begins from 6, and ends to 7. Visually it could be viewed as:
+    #
+    #     0  1  2  3  4  5  6  7
+    #        AAAAAAA
+    #           BBBBBBB
+    #                       CCCC
+    #
+    # The union of A, B, and C would be (1, 4) and (6, 7), therefore the
+    # total running time should be:
+    #
+    #     (4 - 1) + (7 - 6) => 4
+    #
+    # # The Algorithm
+    #
+    # The algorithm used here for union would be described as follow.
+    # First we make sure that all periods are sorted by `Period#first`.
+    # Then we try to merge periods by iterating through the first period
+    # to the last period. The goal would be merging all overlapped periods
+    # so that in the end all the periods are discrete. When all periods
+    # are discrete, we're free to just sum all the periods to get real
+    # running time.
+    #
+    # Here we begin from A, and compare it to B. We could find that
+    # before A ends, B already started. That is `B.first <= A.last`
+    # that is `2 <= 3` which means A and B are overlapping!
+    #
+    # When we found that two periods are overlapping, we would need to merge
+    # them into a new period and disregard the old periods. To make a new
+    # period, we take `A.first` as the new first because remember? we sorted
+    # them, so `A.first` must be smaller or equal to `B.first`. And we take
+    # `[A.last, B.last].max` as the new last because we want whoever ended
+    # later. This could be broken into two cases:
+    #
+    #     0  1  2  3  4
+    #        AAAAAAA
+    #           BBBBBBB
+    #
+    # Or:
+    #
+    #     0  1  2  3  4
+    #        AAAAAAAAAA
+    #           BBBB
+    #
+    # So that we need to take whoever ends later. Back to our example,
+    # after merging and discard A and B it could be visually viewed as:
+    #
+    #     0  1  2  3  4  5  6  7
+    #        DDDDDDDDDD
+    #                       CCCC
+    #
+    # Now we could go on and compare the newly created D and the old C.
+    # We could figure out that D and C are not overlapping by checking
+    # `C.first <= D.last` is `false`. Therefore we need to keep both C
+    # and D. The example would end here because there are no more jobs.
+    #
+    # After having the union of all periods, we just need to sum the length
+    # of all periods to get total time.
+    #
+    #     (4 - 1) + (7 - 6) => 4
+    #
+    # That is 4 is the answer in the example.

 /*= provides tasklist:disabled */
-
-
 /*= provides tasklist:change */
-
-
 /*= provides tasklist:changed */
-
+//
+//
+// Enables Task List update behavior.
+//
+// ### Example Markup
+//
+//   <div class="js-task-list-container">
+//     <ul class="task-list">
+//       <li class="task-list-item">
+//         <input type="checkbox" class="js-task-list-item-checkbox" disabled />
+//         text
+//       </li>
+//     </ul>
+//     <form>
+//       <textarea class="js-task-list-field">- [ ] text</textarea>
+//     </form>
+//   </div>
+//
+// ### Specification
+//
+// TaskLists MUST be contained in a `(div).js-task-list-container`.
+//
+// TaskList Items SHOULD be an a list (`UL`/`OL`) element.
+//
+// Task list items MUST match `(input).task-list-item-checkbox` and MUST be
+// `disabled` by default.
+//
+// TaskLists MUST have a `(textarea).js-task-list-field` form element whose
+// `value` attribute is the source (Markdown) to be udpated. The source MUST
+// follow the syntax guidelines.
+//
+// TaskList updates trigger `tasklist:change` events. If the change is
+// successful, `tasklist:changed` is fired. The change can be canceled.
+//
+// jQuery is required.
+//
+// ### Methods
+//
+// `.taskList('enable')` or `.taskList()`
+//
+// Enables TaskList updates for the container.
+//
+// `.taskList('disable')`
+//
+// Disables TaskList updates for the container.
+//
+//# ### Events
+//
+// `tasklist:enabled`
+//
+// Fired when the TaskList is enabled.
+//
+// * **Synchronicity** Sync
+// * **Bubbles** Yes
+// * **Cancelable** No
+// * **Target** `.js-task-list-container`
+//
+// `tasklist:disabled`
+//
+// Fired when the TaskList is disabled.
+//
+// * **Synchronicity** Sync
+// * **Bubbles** Yes
+// * **Cancelable** No
+// * **Target** `.js-task-list-container`
+//
+// `tasklist:change`
+//
+// Fired before the TaskList item change takes affect.
+//
+// * **Synchronicity** Sync
+// * **Bubbles** Yes
+// * **Cancelable** Yes
+// * **Target** `.js-task-list-field`
+//
+// `tasklist:changed`
+//
+// Fired once the TaskList item change has taken affect.
+//
+// * **Synchronicity** Sync
+// * **Bubbles** Yes
+// * **Cancelable** No
+// * **Target** `.js-task-list-field`
+//
+// ### NOTE
+//
+// Task list checkboxes are rendered as disabled by default because rendered
+// user content is cached without regard for the viewer.

+# - Navigating to the `CI/CD Pipelines` settings of your project,
+# - Copying and pasting the default `Simplecov` regex example provided, i.e.,
+#   `\(\d+.\d+\%\) covered` in the `test coverage parsing` textfield.
