 ## Workflow labels
 
-Labelling issues is described in the [GitLab Inc engineering workflow].
+To allow for asynchronous issue handling, we use [milestones][milestones-page]
+and [labels][labels-page]. Leads and product managers handle most of the
+scheduling into milestones. Labelling is a task for everyone.
 
-## Implement design & UI elements
+Most issues will have labels for at least one of the following:
 
-Please see the [UX Guide for GitLab].
+- Type: ~"feature proposal", ~bug, ~customer, etc.
+- Subject: ~wiki, ~"container registry", ~ldap, ~api, etc.
+- Team: ~CI, ~Discussion, ~Edge, ~Frontend, ~Platform, etc.
+- Priority: ~Deliverable, ~Stretch
+
+All labels, their meaning and priority are defined on the
+[labels page][labels-page].
+
+If you come across an issue that has none of these, and you're allowed to set
+labels, you can _always_ add the team and type, and often also the subject.
+
+[milestones-page]: https://gitlab.com/gitlab-org/gitlab-ce/milestones
+[labels-page]: https://gitlab.com/gitlab-org/gitlab-ce/labels
+
+### Type labels (~"feature proposal", ~bug, ~customer, etc.)
+
+Type labels are very important. They define what kind of issue this is. Every
+issue should have one or more.
+
+Examples of type labels are ~"feature proposal", ~bug, ~customer, ~security,
+and ~"direction".
+
+A number of type labels have a priority assigned to them, which automatically
+makes them float to the top, depending on their importance.
+
+Type labels are always lowercase, and can have any color, besides blue (which is
+already reserved for subject labels).
+
+The descriptions on the [labels page][labels-page] explain what falls under each type label.
+
+### Subject labels (~wiki, ~"container registry", ~ldap, ~api, etc.)
+
+Subject labels are labels that define what area or feature of GitLab this issue
+hits. They are not always necessary, but very convenient.
+
+If you are an expert in a particular area, it makes it easier to find issues to
+work on. You can also subscribe to those labels to receive an email each time an
+issue is labelled with a subject label corresponding to your expertise.
+
+Examples of subject labels are ~wiki, ~"container registry", ~ldap, ~api,
+~issues, ~"merge requests", ~labels, and ~"container registry".
+
+Subject labels are always all-lowercase.
+
+### Team labels (~CI, ~Discussion, ~Edge, ~Platform, etc.)
+
+Team labels specify what team is responsible for this issue.
+Assigning a team label makes sure issues get the attention of the appropriate
+people.
+
+The current team labels are ~Build, ~CI, ~Discussion, ~Documentation, ~Edge,
+~Gitaly, ~Platform, ~Prometheus, ~Release, and ~"UX".
+
+The descriptions on the [labels page][labels-page] explain what falls under the
+responsibility of each team.
+
+Within those team labels, we also have the ~backend and ~frontend labels to
+indicate if an issue needs backend work, frontend work, or both.
+
+Team labels are always capitalized so that they show up as the first label for
+any issue.
 
-## Release retrospective and kickoff
+### Priority labels (~Deliverable and ~Stretch)
 
-### Retrospective
+Priority labels help us clearly communicate expectations of the work for the
+release. There are two levels of priority labels:
 
-After each release, we have a retrospective call where we discuss what went well,
-what went wrong, and what we can improve for the next release. The

+Community contributors can submit merge requests for any issue they want, but
+the ~"Accepting Merge Requests" label has a special meaning. It points to
+changes that:
+
+1. We already agreed on,
+1. Are well-defined,
+1. Are likely to get accepted by a maintainer.
+
+We want to avoid a situation when a contributor picks an
+~"Accepting Merge Requests" issue and then their merge request gets closed,
+because we realize that it does not fit our vision, or we want to solve it in a
+different way.
+
+We add the ~"Accepting Merge Requests" label to:
+
+- Low priority ~bug issues (i.e. we do not add it to the bugs that we want to
+solve in the ~"Next Patch Release")
+- Small ~"feature proposal" that do not need ~UX / ~"Product work", or for which
+the ~UX / ~"Product work" is already done
+- Small ~"technical debt" issues
+
+After adding the ~"Accepting Merge Requests" label, we try to estimate the
+[weight](#issue-weight) of the issue. We use issue weight to let contributors
+know how difficult the issue is. Additionally:
+
+- We advertise [~"Accepting Merge Requests" issues with weight < 5][up-for-grabs]
+  as suitable for people that have never contributed to GitLab before on the
+  [Up For Grabs campaign](http://up-for-grabs.net)
+- We encourage people that have never contributed to any open source project to
+  look for [~"Accepting Merge Requests" issues with a weight of 1][firt-timers]

+
+Our issue triage policies are [described in our handbook]. You are very welcome
+to help the GitLab team triage issues. We also organize [issue bash events] once
+every quarter.
+
+The most important thing is making sure valid issues receive feedback from the
+development team. Therefore the priority is mentioning developers that can help

 ## Purpose of describing the contributing process
 
-Below we describe the contributing process to GitLab for two reasons. So that
-contributors know what to expect from maintainers (possible responses, friendly
-treatment, etc.). And so that maintainers know what to expect from contributors
-(use the latest version, ensure that the issue is addressed, friendly treatment,

 ## Common actions
 
-### Issue triaging
-
-Our issue triage policies are [described in our handbook]. You are very welcome
-to help the GitLab team triage issues. We also organize [issue bash events] once
-every quarter.
-
-The most important thing is making sure valid issues receive feedback from the
-development team. Therefore the priority is mentioning developers that can help
-on those issues. Please select someone with relevant experience from
-[GitLab team][team]. If there is nobody mentioned with that expertise
-look in the commit history for the affected files to find someone. Avoid
-mentioning the lead developer, this is the person that is least likely to give a
-timely response. If the involvement of the lead developer is needed the other
-core team members will mention this person.

 ## Assigning issues
 
 If an issue is complex and needs the attention of a specific person, assignment is a good option but assigning issues might discourage other people from contributing to that issue. We need all the contributions we can get so this should never be discouraged. Also, an assigned person might not have time for a few weeks, so others should feel free to takeover.

+### Retrospective
+
+After each release, we have a retrospective call where we discuss what went well,
+what went wrong, and what we can improve for the next release. The

+If you're interested, you can even join the
+[retrospective call][retro-kickoff-call], on the first working day after the

+Before working on the next release, we have a
+kickoff call to explain what we expect to ship in the next release. The

+# Serializers
+
+This is a documentation for classes located in `app/serializers` directory.
+
+In GitLab, we use [grape-entities][grape-entity-project], accompanied by a
+serializer, to convert a Ruby object to its JSON representation.
+
+Serializers are typically used in controllers to build a JSON response
+that is usually consumed by a frontend code.
+
+## Why using a serializer is important?
+
+Using serializers, instead of `to_json` method, has several benefits:
+
+* it helps to prevent exposure of a sensitive data stored in the database
+* it makes it easier to test what should and should not be exposed
+* it makes it easier to reuse serialization entities that are building blocks
+* it makes it easier to move complexity from controllers to easily testable
+  classes
+* it encourages hiding complexity behind intentions-revealing interfaces
+* it makes it easier to take care about serialization performance concerns
+* it makes it easier to reduce merge conflicts between CE -> EE
+* it makes it easier to benefit from domain driven development techniques
+
+## What is a serializer?
+
+A serializer is a class that encapsulates all business rules for building a
+JSON response using serialization entities.
+
+It is designed to be testable and to support passing additional context from
+the controller.
+
+## What is a serialization entity?
+
+Entities are lightweight structures that allow to represent domain models
+in a consistent and abstracted way, and reuse them as building blocks to
+create a payload.
+
+Entities located in `app/serializers` are usually derived from a
+[`Grape::Entity`][grape-entity-class] class.
+
+Serialization entities that do require to have a knowledge about specific
+elements of the request, need to mix `RequestAwareEntity` in.
+
+A serialization entity usually maps a domain model class into its JSON
+representation. It rarely happens that a serialization entity exists without
+a corresponding domain model class. As an example, we have an `Issue` class and
+a corresponding `IssueSerializer`.
+
+Serialization entites are designed to reuse other serialization entities, which
+is a convenient way to create a multi-level JSON representation of a piece of
+a domain model you want to serialize.
+
+See [documentation for Grape Entites][grape-entity-readme] for more details.
+
+## How to implement a serializer?
+
+### Base implementation
+
+In order to effectively implement a serializer it is necessary to create a new
+class in `app/serializers`. See existing serializers as an example.
+
+A new serializer should inherit from a `BaseSerializer` class. It is necessary
+to specify which serialization entity will be used to serialize a resource.
+
+```ruby
+class MyResourceSerializer < BaseSerialize
+  entity MyResourceEntity
+end
+```
+
+The example above shows how a most simple serializer can look like.
+
+Given that the entity `MyResourceEntity` exists, you can now use
+`MyResourceSerializer` in the controller by creating an instance of it, and
+calling `MyResourceSerializer#represent(resource)` method.
+
+Note that a `resource` can be either a single object, an array of objects or an
+`ActiveRecord::Relation` object. A serialization entity should be smart enough
+to accurately represent each of these.
+
+It should not be necessary to use `Enumerable#map`, and it should be avoided
+from the performance reasons.
+
+### Choosing what gets serialized
+
+It often happens that you might want to use the same serializer in many places,
+but sometimes the intention is to only expose a small subset of object's
+attributes in one place, and a different subset in another.
+
+`BaseSerializer#represent(resource, opts = {})` method can take an additional
+hash argument, `opts`, that defines what is going to be serialized.
+
+`BaseSerializer` will pass these options to a serialization entity. See
+how it is [documented in the upstream project][grape-entity-only].
+
+With this approach you can extend the serializer to respond to methods that will
+create a JSON response according to your needs.
+
+```ruby
+class PipelineSerializer < BaseSerializer
+  entity PipelineEntity
+
+  def represent_details(resource)
+    represent(resource, only: [:details])
+  end
+
+  def represent_status(resource)
+    represent(resource, only: [:status])
+  end
+end
+```
+
+It is possible to use `only` and `except` keywords. Both keywords do support
+nested attributes, like `except: [:id, { user: [:id] }]`.
+
+Passing `only` and `except` to the `represent` method from a controller is
+possible, but it defies principles of encapsulation and testability, and it is
+better to avoid it, and to add a specific method to the serializer instead.
+
+### Reusing serialization entities from the API
+
+Public API in GitLab is implemented using [Grape][grape-project].
+
+Under the hood it also uses [`Grape::Entity`][grape-entity-class] classes.
+This means that it is possible to reuse these classes to implement internal
+serializers.
+
+You can either use such entity directly:
+
+```ruby
+class MyResourceSerializer < BaseSerializer
+  entity API::Entities::SomeEntity
+end
+```
+
+Or derive a new serialization entity class from it:
+
+```ruby
+class MyEntity < API::Entities::SomeEntity
+  include RequestAwareEntity
+
+  unexpose :something
+end
+```
+
+It might be a good idea to write specs for entities that do inherit from
+the API, because when API payloads are changed / extended, it is easy to forget
+about the impact on the internal API through a serializer that reuses API
+entities.
+
+It is usually safe to do that, because API entities rarely break backward
+compatibility, but additional exposure may have a performance impact when API
+gets extended significantly. Write tests that check if only necessary data is
+exposed.
+
+## How to write tests for a serializer?
+
+Like every other class in the project, creating a serializer warrants writing
+tests for it.
+
+It is usually a good idea to test each public method in the serializer against
+a valid payload. `BaseSerializer#represent` returns a hash, so it is possible
+to use usual RSpec matchers like `include`.
+
+Sometimes, when the payload is large, it makes sense to validate it entirely
+using `match_response_schema` matcher along with a new fixture that can be
+stored in `spec/fixtures/api/schemas/`. This matcher is using a `json-schema`
+gem, which is quite flexible, see a [documentation][json-schema-gem] for it.
+
+## How to use a serializer in a controller?
+
+Once a new serializer is implemented, it is possible to use it in a controller.
+
+Create an instance of the serializer and render the response.
+
+```ruby
+def index
+  format.json do
+    render json: MyResourceSerializer
+      .new(current_user: @current_user)
+      .represent_details(@project.resources)
+  nd
+end
+```
+
+If it is necessary to include additional information in the payload, it is
+possible to extend what is going to be rendered, the usual way:
+
+```ruby
+def index
+  format.json do
+    render json: {
+      resources: MyResourceSerializer
+        .new(current_user: @current_user)
+        .represent_details(@project.resources),
+      count: @project.resources.count
+    }
+  nd
+end
+```
+
+Note that in these examples an additional context is being passed to the
+serializer (`current_user: @current_user`).
+
+## How to pass an additional context from the controller?
+
+It is possible to pass an additional context from a controller to a
+serializer and each serialization entity that is used in the process.
+
+Serialization entities that do require an additional context have
+`RequestAwareEntity` concern mixed in. This piece of the code exposes a method
+called `request` in every serialization entity that is instantiated during
+serialization.
+
+An object returned by this method is an instance of `EntityRequest`, which
+behaves like an `OpenStruct` object, with the difference that it will raise
+an error if an unknown method is called.
+
+In other words, in the previous example, `request` method will return an
+instance of `EntityRequest` that responds to `current_user` method. It will be
+available in every serialization entity instantiated by `MyResourceSerializer`.
+
+`EntityRequest` is a workaround for [#20045][issue-20045] and is meant to be
+refactored soon. Please avoid passing an additional context that is not
+required by a serialization entity.
+
+At the moment, the context that is passed to entities most often is
+`current_user` and `project`.
+
+## How is this related to using presenters?
+
+Payload created by a serializer is usually a representation of the backed code,
+combined with the current request data. Therefore, technically, serializers
+are presenters that create payload consumed by a frontend code, usually Vue
+components.
+
+In GitLab, it is possible to use [presenters][presenters-readme], but
+`BaseSerializer` still needs to learn how to use it, see [#30898][issue-30898].
+
+It is possible to use presenters when serializer is used to represent only
+a single object. It is not supported when  `ActiveRecord::Relation` is being
+serialized.
+
+```ruby
+MyObjectSerializer.new.represent(object.present)
+```
+
+## Best practices
+
+1. Do not invoke a serializer from within a serialization entity.
+
+    If you need to use a serializer from within a serialization entity, it is
+    possible that you are missing a class for an important domain concept.
+
+    Consider creating a new domain class and a corresponding serialization
+    entity for it.
+
+1. Use only one approach to switch behavior of the serializer.
+
+    It is possible to use a few approaches to switch a behavior of the
+    serializer. Most common are using a [Fluent Interface][fluent-interface]
+    and creating a separate `represent_something` methods.
+
+    Whatever you choose, it might be better to use only one approach at a time.
+
+1. Do not forget about creating specs for serialization entities.
+
+    Writing tests for the serializer indeed does cover testing a behavior of
+    serialization entities that the serializer instantiates. However it might
+    be a good idea to write separate tests for entities as well, because these
+    are meant to be reused in different serializers, and a serializer can
+    change a behavior of a serialization entity.
+
+1. Use `ActiveRecord::Relation` where possible
+
+    Using an `ActiveRecord::Relation` might help from the performance perspective.
+
+1. Be diligent about passing an additional context from the controller.
+
+    Using `EntityRequest` and `RequestAwareEntity` is a workaround for the lack
+    of high-level mechanism. It is meant to be refactored, and current
+    implementation is error prone. Imagine the situation that one serialization
+    entity requires `request.user` attribute, but the second one wants
+    `request.current_user`. When it happens that these two entities are used in
+    the same serialization request, you might need to pass both parameters to
+    the serializer, which is obviously not a perfect situation.
+
+    When in doubt, pass only `current_user` and `project` if these are required.
+
+1. Keep performance concerns in mind
+
+    Using a serializer incorrectly can have significant impact on the
+    performance.
+
+    Because serializers are technically presenters, it is often necessary
+    to calculate, for example, paths to various controller-actions.
+    Since using URL helpers usually involve passing `project` and `namespace`
+    adding `includes(project: :namespace)` in the serializer, can help to avoid
+    N+1 queries.
+
+    Also, try to avoid using `Enumerable#map` or other methods that will
+    execute a database query eagerly.
+
+1. Avoid passing `only` and `except` from the controller.
+1. Write tests checking for N+1 queries.
+1. Write controller tests for actions / formats using serializers.
+1. Write tests that check if only necessary data is exposed.

+
+## Introduction
+
+Managing a large number of users in GitLab can become a burden for system administrators. As an organization grows so do user accounts. Keeping these user accounts in sync across multiple enterprise applications often becomes a time consuming task.
+
+In this guide we will focus on configuring GitLab with Active Directory. [Active Directory](https://en.wikipedia.org/wiki/Active_Directory) is a popular LDAP compatible directory service provided by Microsoft, included in all modern Windows Server operating systems.
+
+GitLab has supported LDAP integration since [version 2.2](https://about.gitlab.com/2012/02/22/gitlab-version-2-2/). With GitLab LDAP [group syncing](#group-syncing-ee) being added to GitLab Enterprise Edition in [version 6.0](https://about.gitlab.com/2013/08/20/gitlab-6-dot-0-released/). LDAP integration has become one of the most popular features in GitLab.
+
+## Getting started
+
+### Choosing an LDAP Server
+
+The main reason organizations choose to utilize a LDAP server is to keep the entire organization's user base consolidated into a central repository. Users can access multiple applications and systems across the  IT environment using a single login. Because LDAP is an open, vendor-neutral, industry standard application protocol, the number of applications using LDAP authentication continues to increase.
+
+There are many commercial and open source [directory servers](https://en.wikipedia.org/wiki/Directory_service#LDAP_implementations) that support the LDAP protocol. Deciding on the right directory server highly depends on the existing IT environment in which the server will be integrated with.
+
+For example, [Active Directory](https://technet.microsoft.com/en-us/library/hh831484(v=ws.11).aspx) is generally favored in a primarily Windows environment, as this allows quick integration with existing services. Other popular directory services include:
+
+- [Oracle Internet Directory](http://www.oracle.com/technetwork/middleware/id-mgmt/overview/index-082035.html)
+- [OpenLDAP](http://www.openldap.org/)
+- [389 Directory](http://directory.fedoraproject.org/)
+- [OpenDJ](https://forgerock.org/opendj/)
+- [ApacheDS](https://directory.apache.org/)
+
+> GitLab uses the [Net::LDAP](https://rubygems.org/gems/net-ldap) library under the hood. This means it supports all [IETF](https://tools.ietf.org/html/rfc2251) compliant LDAPv3 servers.
+
+### Active Directory (AD)
+
+We won't cover the installation and configuration of Windows Server or Active Directory Domain Services in this tutorial. There are a number of resources online to guide you through this process:
+
+- Install Windows Server 2012  - (_technet.microsoft.com_) - [Installing Windows Server 2012 ](https://technet.microsoft.com/en-us/library/jj134246(v=ws.11).aspx)
+
+- Install Active Directory Domain Services (AD DS) (_technet.microsoft.com_)- [Install Active Directory Domain Services](https://technet.microsoft.com/windows-server-docs/identity/ad-ds/deploy/install-active-directory-domain-services--level-100-#BKMK_PS)
+
+> **Shortcut:** You can quickly install AD DS via PowerShell using
+`Install-WindowsFeature AD-Domain-Services -IncludeManagementTools`
+
+### Creating an AD **OU** structure
+
+Configuring organizational units (**OU**s) is an important part of setting up Active Directory. **OU**s form the base for an entire organizational structure. Using GitLab as an example we have designed the **OU** structure below using the geographic **OU** model. In the Geographic Model we separate **OU**s for different geographic regions.
+
+| GitLab **OU** Design           |  GitLab AD Structure             |
+| :----------------------------: | :------------------------------: |
+| ![GitLab OU Design][gitlab_ou] |  ![GitLab AD Structure][ldap_ou] |
+
+[gitlab_ou]: img/gitlab_ou.png
+[ldap_ou]: img/ldap_ou.gif
+
+Using PowerShell you can output the **OU** structure as a table (_all names are examples only_):
+
+```ps
+Get-ADObject -LDAPFilter "(objectClass=*)" -SearchBase 'OU=GitLab INT,DC=GitLab,DC=org' -Properties CanonicalName | Format-Table Name,CanonicalName -A
+```
+
+```

+
+## GitLab LDAP configuration
+
+The initial configuration of LDAP in GitLab requires changes to the `gitlab.rb` configuration file. Below is an example of a complete configuration using an Active Directory.
+
+The two Active Directory specific values are `active_directory: true` and `uid: 'sAMAccountName'`. `sAMAccountName` is an attribute returned by Active Directory used for GitLab usernames. See the example output from `ldapsearch` for a full list of attributes a "person" object (user) has in **AD** - [`ldapsearch` example](#using-ldapsearch-unix)
+
+> Both group_base and admin_group configuration options are only available in GitLab Enterprise Edition. See [GitLab EE - LDAP Features](#gitlab-enterprise-edition---ldap-features)
+
+### Example `gitlab.rb` LDAP
+
+```
+gitlab_rails['ldap_enabled'] = true
+gitlab_rails['ldap_servers'] = {
+'main' => {
+  'label' => 'GitLab AD',
+  'host' =>  'ad.example.org',
+  'port' => 636,
+  'uid' => 'sAMAccountName',
+  'method' => 'ssl',
+  'bind_dn' => 'CN=GitLabSRV,CN=Users,DC=GitLab,DC=org',
+  'password' => 'Password1',
+  'active_directory' => true,
+  'base' => 'OU=GitLab INT,DC=GitLab,DC=org',
+  'group_base' => 'OU=Global Groups,OU=GitLab INT,DC=GitLab,DC=org',
+  'admin_group' => 'Global Admins'
+  }
+}
+```
+
+> **Note:** Remember to run  `gitlab-ctl reconfigure` after modifying `gitlab.rb`
+
+## Security improvements (LDAPS)
+
+Security is an important aspect when deploying an LDAP server. By default, LDAP traffic is transmitted unsecured. LDAP can be secured using SSL/TLS called LDAPS, or commonly "LDAP over SSL".
+
+Securing LDAP (enabling LDAPS) on Windows Server 2012 involves installing a valid SSL certificate. For full details see Microsoft's guide [How to enable LDAP over SSL with a third-party certification authority](https://support.microsoft.com/en-us/help/321051/how-to-enable-ldap-over-ssl-with-a-third-party-certification-authority)
+
+> By default a LDAP service listens for connections on TCP and UDP port 389. LDAPS (LDAP over SSL) listens on port 636
+
+### Testing you AD server
+
+#### Using **AdFind** (Windows)
+
+You can use the [`AdFind`](https://social.technet.microsoft.com/wiki/contents/articles/7535.adfind-command-examples.aspx) utility (on Windows based systems) to test that your LDAP server is accessible and authentication is working correctly. This is a freeware utility built by [Joe Richards](http://www.joeware.net/freetools/tools/adfind/index.htm).
+
+**Return all objects**
+
+You can use the filter `objectclass=*` to return all directory objects.
+
+```sh
+adfind -h ad.example.org:636 -ssl -u "CN=GitLabSRV,CN=Users,DC=GitLab,DC=org" -up Password1 -b "OU=GitLab INT,DC=GitLab,DC=org" -f (objectClass=*)
+```
+
+**Return single object using filter**
+
+You can also retrieve a single object by **specifying** the object name or full **DN**. In this example we specify the object name only `CN=Leroy Fox`.
+
+```sh
+adfind -h ad.example.org:636 -ssl -u "CN=GitLabSRV,CN=Users,DC=GitLab,DC=org" -up Password1 -b "OU=GitLab INT,DC=GitLab,DC=org" -f (&(objectcategory=person)(CN=Leroy Fox))”
+```
+
+#### Using **ldapsearch** (Unix)
+
+You can use the `ldapsearch` utility (on Unix based systems) to test that your LDAP server is accessible and authentication is working correctly. This utility is included in the [`ldap-utils`](https://wiki.debian.org/LDAP/LDAPUtils) package.
+
+**Return all objects**
+
+You can use the filter `objectclass=*` to return all directory objects.
+
+```sh
+ldapsearch -D "CN=GitLabSRV,CN=Users,DC=GitLab,DC=org" \
+-w Password1 -p 636 -h ad.example.org \
+-b "OU=GitLab INT,DC=GitLab,DC=org" -Z \
+-s sub "(objectclass=*)"
+```
+
+**Return single object using filter**
+
+You can also retrieve a single object by **specifying** the object name or full **DN**. In this example we specify the object name only `CN=Leroy Fox`.
+
+```sh
+ldapsearch -D "CN=GitLabSRV,CN=Users,DC=GitLab,DC=org" -w Password1 -p 389 -h ad.example.org -b "OU=GitLab INT,DC=GitLab,DC=org" -Z -s sub "CN=Leroy Fox"
+```
+
+**Full output of `ldapsearch` command:** - Filtering for _CN=Leroy Fox_
+
+```
+# LDAPv3
+# base <OU=GitLab INT,DC=GitLab,DC=org> with scope subtree
+# filter: CN=Leroy Fox

+
+## Basic user authentication
+
+After configuring LDAP, basic authentication will be available. Users can then login using their directory credentials. An extra tab is added to the GitLab login screen for the configured LDAP server (e.g "**GitLab AD**").
+
+![GitLab OU Structure](img/user_auth.gif)
+
+Users that are removed from the LDAP base group (e.g `OU=GitLab INT,DC=GitLab,DC=org`) will be **blocked** in GitLab. [More information](../../administration/auth/ldap.md#security) on LDAP security.
+
+If `allow_username_or_email_login` is enabled in the LDAP configuration, GitLab will ignore everything after the first '@' in the LDAP username used on login. Example: The username `jon.doe@example.com` is converted to `jon.doe` when authenticating with the LDAP server. Disable this setting if you use `userPrincipalName` as the `uid`.
+
+## LDAP extended features on GitLab EE
+
+With [GitLab Enterprise Edition (EE)](https://about.gitlab.com/giltab-ee/), besides everything we just described, you'll
+have extended functionalities with LDAP, such as:
+
+- Group sync
+- Group permissions
+- Updating user permissions
+- Multiple LDAP servers
+

+# Pipeline Schedules
+
+> **Note**:
+- This feature was introduced in 9.1 as [Trigger Schedule][ce-105533]
+- In 9.2, the feature was [renamed to Pipeline Schedule][ce-10853]
+
+Pipeline schedules can be used to run pipelines only once, or for example every
+month on the 22nd for a certain branch.
+
+## Using Pipeline Schedules
+
+In order to schedule pipelines, navigate to your their pages **Pipelines ➔ Schedules**
+and click the **New Schedule** button.
+
+![New Schedule Form](img/pipeline_schedules_new_form.png)
+
+After entering the form, hit **Save Schedule** for the changes to have effect.
+You can check a next execution date of the scheduled trigger, which is automatically calculated by a server.
+
+## Taking ownership
+
+![Schedules list](img/pipeline_schedules_list.png)
+
+Pipelines are executed as a user, which owns a schedule. This influences what
+projects and other resources the pipeline has access to. If a user does not own
+a pipeline, you can take ownership by clicking the **Take ownership** button.
+The next time a pipeline is scheduled, your credentials will be used.
+
+> **Notes**:
+- Those pipelines won't be executed precicely. Because schedules are handled by
+Sidekiq, which runs according to its interval. For exmaple, if you set a schedule to
+create a pipeline every minute (`* * * * *`) and the Sidekiq worker performs 00:00
+and 12:00 o'clock every day (`0 */12 * * *`), only 2 pipelines will be created per day.
+To change the Sidekiq worker's frequency, you have to edit the `trigger_schedule_worker_cron`
+value in your `gitlab.rb` and restart GitLab. The Sidekiq worker's configuration
+on GiLab.com is able to be looked up at [here](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/config/gitlab.yml.example#L185).
+- Cron notation is parsed by [Rufus-Scheduler](https://github.com/jmettraux/rufus-scheduler).

+
+## Pipeline graphs
+
+> [Introduced][ce-5742] in GitLab 8.11.
+
+Pipelines can be complex structures with many sequential and parallel jobs.
+To make it a little easier to see what is going on, you can view a graph
+of a single pipeline and its status.
+
+A pipeline graph can be shown in two different ways depending on what page you
+are on.
+
+---
+
+The regular pipeline graph that shows the names of the jobs of each stage can
+be found when you are on a [single pipeline page](#seeing-pipeline-status).
+
+![Pipelines example](img/pipelines.png)
+
+Then, there is the pipeline mini graph which takes less space and can give you a
+quick glance if all jobs pass or something failed. The pipeline mini graph can
+be found when you visit:
+
+- the pipelines index page
+- a single commit page
+- a merge request page
+
+That way, you can see all related jobs for a single commit and the net result
+of each stage of your pipeline. This allows you to quickly see what failed and
+fix it. Stages in pipeline mini graphs are collapsible. Hover your mouse over
+them and click to expand their jobs.
+
+| **Mini graph** | **Mini graph expanded** |
+| :------------: | :---------------------: |
+| ![Pipelines mini graph](img/pipelines_mini_graph_simple.png) | ![Pipelines mini graph extended](img/pipelines_mini_graph.png) |
+
+### Grouping similar jobs in the pipeline graph
+
+> [Introduced][ce-6242] in GitLab 8.12.
+
+If you have many similar jobs, your pipeline graph becomes very long and hard
+to read. For that reason, similar jobs can automatically be grouped together.
+If the job names are formatted in certain ways, they will be collapsed into
+a single group in regular pipeline graphs (not the mini graphs).
+You'll know when a pipeline has grouped jobs if you don't see the retry or
+cancel button inside them. Hovering over them will show the number of grouped
+jobs. Click to expand them.
+
+![Grouped pipelines](img/pipelines_grouped.png)
+
+The basic requirements is that there are two numbers separated with one of
+the following (you can even use them interchangeably):
+
+- a space
+- a backslash (`/`)
+- a colon (`:`)
+
+>**Note:**
+More specifically, [it uses][regexp] this regular expression: `\d+[\s:\/\\]+\d+\s*`.
+
+The jobs will be ordered by comparing those two numbers from left to right. You
+usually want the first to be the index and the second the total.
+
+For example, the following jobs will be grouped under a job named `test`:
+
+- `test 0 3` => `test`
+- `test 1 3` => `test`
+- `test 2 3` => `test`
+
+The following jobs will be grouped under a job named `test ruby`:
+
+- `test 1:2 ruby` => `test ruby`
+- `test 2:2 ruby` => `test ruby`
+
+The following jobs will be grouped under a job named `test ruby` as well:
+
+- `1/3 test ruby` => `test ruby`
+- `2/3 test ruby` => `test ruby`
+- `3/3 test ruby` => `test ruby`
+
+### Manual actions from the pipeline graph
+
+> [Introduced][ce-7931] in GitLab 8.15.
+
+[Manual actions][manual] allow you to require manual interaction before moving
+forward with a particular job in CI. Your entire pipeline can run automatically,
+but the actual [deploy to production][env-manual] will require a click.
+
+You can do this straight from the pipeline graph. Just click on the play button
+to execute that particular job. For example, in the image below, the `production`
+stage has a job with a manual action.
+
+![Pipelines example](img/pipelines.png)
+
+### Ordering of jobs in pipeline graphs
+
+**Regular pipeline graph**
+
+In the single pipeline page, jobs are sorted by name.
+
+**Mini pipeline graph**
+
+> [Introduced][ce-9760] in GitLab 9.0.
+
+In the pipeline mini graphs, the jobs are sorted first by severity and then
+by name. The order of severity is:
+
+- failed
+- warning
+- pending
+- running
+- manual
+- canceled
+- success
+- skipped
+- created

-> **Notes**:
-- Those triggers won't be executed precicely. Because scheduled triggers are handled by Sidekiq, which runs according to its interval. For exmaple, if you set a trigger to be executed every minute (`* * * * *`) and the Sidekiq worker performs 00:00 and 12:00 o'clock every day (`0 */12 * * *`), then your trigger will be executed only 00:00 and 12:00 o'clock every day. To change the Sidekiq worker's frequency, you have to edit the `trigger_schedule_worker` value in `config/gitlab.yml` and restart GitLab. The Sidekiq worker's configuration on GiLab.com is able to be looked up at [here](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/config/gitlab.yml.example#L185).

+# Building a package for testing
+
+While developing a new feature or modifying an existing one, it is helpful if an
+installable package (or a docker image) containing those changes is available
+for testing. For this very purpose, a manual job is provided in the GitLab CI/CD
+pipeline that can be used to trigger a pipeline in the omnibus-gitlab repository
+that will create
+1. A deb package for Ubuntu 16.04, available as a build artifact, and
+2. A docker image, which is pushed to [Omnibus GitLab's container 
+registry](https://gitlab.com/gitlab-org/omnibus-gitlab/container_registry)
+(images titled `gitlab-ce` and `gitlab-ee` respectively and image tag is the
+commit which triggered the pipeline).
+
+When you push a commit to either the gitlab-ce or gitlab-ee project, the
+pipeline for that commit will have a `build-package` manual action you can
+trigger.
+
+![Manual actions](img/trigger_ss1.png)
+
+![Build package manual action](img/trigger_ss2.png)
+
+## Specifying versions of components
+
+If you want to create a package from a specific branch, commit or tag of any of
+the GitLab components (like GitLab Workhorse, Gitaly, GitLab Pages, etc.), you
+can specify the branch name, commit sha or tag in the component's respective
+`*_VERSION` file. For example, if you want to build a package that uses the
+branch `0-1-stable`, modify the content of `GITALY_SERVER_VERSION` to
+`0-1-stable` and push the commit. This will create a manual job that can be
+used to trigger the build.
+
+## Specifying the branch in omnibus-gitlab repository
+
+In scenarios where a configuration change is to be introduced and omnibus-gitlab
+repository already has the necessary changes in a specific branch, you can build
+a package against that branch through an environment variable named
+`OMNIBUS_BRANCH`. To do this, specify that environment variable with the name of
+the branch as value in `.gitlab-ci.yml` and push a commit. This will create a
+manual job that can be used to trigger the build.

 ### Vue.js
 
-
 #### Basic Rules
-- Only include one Vue.js component per file.
-- Export components as plain objects:
-
+1. The service has it's own file
+1. The store has it's own file
+1. Use a function in the bundle file to instantiate the Vue component:
   ```javascript
-  export default {
-    template: `<h1>I'm a component</h1>
-  }
-  ```
+    // bad
+    class {
+      init() {
+        new Component({})
+      }
+    }
 
-#### Naming
-- **Extensions**: Use `.vue` extension for Vue components.
-- **Reference Naming**: Use PascalCase for Vue components and camelCase for their instances:
+    // good
+    document.addEventListener('DOMContentLoaded', () => new Vue({
+      el: '#element',
+      components: {
+        componentName
+      },
+      render: createElement => createElement('component-name'),
+    }));
+  ```
 
+1. Don not use a singleton for the service or the store
   ```javascript
-  // bad
-  import cardBoard from 'cardBoard';
+    // bad
+    class Store {
+      constructor() {

+# Foreign Keys & Associations
+
+When adding an association to a model you must also add a foreign key. For
+example, say you have the following model:
+
+```ruby
+class User < ActiveRecord::Base
+  has_many :posts
+end
+```
+
+Here you will need to add a foreign key on column `posts.user_id`. This ensures
+that data consistency is enforced on database level. Foreign keys also mean that
+the database can very quickly remove associated data (e.g. when removing a
+user), instead of Rails having to do this.
+
+## Adding Foreign Keys In Migrations
+
+Foreign keys can be added concurrently using `add_concurrent_foreign_key` as
+defined in `Gitlab::Database::MigrationHelpers`. See the [Migration Style
+Guide](migration_style_guide.md) for more information.
+
+Keep in mind that you can only safely add foreign keys to existing tables after
+you have removed any orphaned rows. The method `add_concurrent_foreign_key`
+does not take care of this so you'll need to do so manually.
+
+## Cascading Deletes
+
+Every foreign key must define an `ON DELETE` clause, and in 99% of the cases
+this should be set to `CASCADE`.
+
+## Indexes
+
+When adding a foreign key in PostgreSQL the column is not indexed automatically,
+thus you must also add a concurrent index. Not doing so will result in cascading
+deletes being very slow.
+
+## Dependent Removals
+
+Don't define options such as `dependent: :destroy` or `dependent: :delete` when
+defining an association. Defining these options means Rails will handle the
+removal of data, instead of letting the database handle this in the most
+efficient way possible.
+
+In other words, this is bad and should be avoided at all costs:
+
+```ruby
+class User < ActiveRecord::Base
+  has_many :posts, dependent: :destroy
+end
+```
+
+Should you truly have a need for this it should be approved by a database
+specialist first.
+
+You should also not define any `before_destroy` or `after_destroy` callbacks on
+your models _unless_ absolutely required and only when approved by database
+specialists. For example, if each row in a table has a corresponding file on a
+file system it may be tempting to add a `after_destroy` hook. This however
+introduces non database logic to a model, and means we can no longer rely on
+foreign keys to remove the data as this would result in the filesystem data
+being left behind. In such a case you should use a service class instead that
+takes care of removing non database data.

+The `path` column for these rows will be renamed to their previous value followed
+by an integer. For example: `users` would turn into `users0`

-
-  1. "Project name" is the name of your project (you can't use special characters,
-     but you can use spaces, hyphens, underscores or even emojis).
-  1. The "Project description" is optional and will be shown in your project's
-     dashboard so others can briefly understand what your project is about.
-  1. Select a [visibility level](../public_access/public_access.md).
-  1. You can also [import your existing projects](../workflow/importing/README.md).
-
-1. Finally, click **Create project**.

+    - Enter the name of your project in the **Project name** field. You can't use
+      special characters, but you can use spaces, hyphens, underscores or even
+      emoji.
+    - If you have a project in a different repository, you can [import it] by
+      clicking an **Import project from** button provided this is enabled in
+      your GitLab instance. Ask your administrator if not.
+    - The **Project description (optional)** field enables you to enter a
+      description for your project's dashboard, which will help others
+      understand what your project is about. Though it's not required, it's a good

+# GitLab Helm Chart
+
+The `gitlab` Helm chart deploys GitLab into your Kubernetes cluster.
+
+This chart includes the following:
+
+- Deployment using the [gitlab-ce](https://hub.docker.com/r/gitlab/gitlab-ce) or [gitlab-ee](https://hub.docker.com/r/gitlab/gitlab-ee) container image
+- ConfigMap containing the `gitlab.rb` contents that configure [Omnibus GitLab](https://docs.gitlab.com/omnibus/settings/configuration.html#configuration-options)
+- Persistent Volume Claims for Data, Config, Logs, and Registry Storage
+- A Kubernetes service
+- Optional Redis deployment using the [Redis Chart](https://github.com/kubernetes/charts/tree/master/stable/redis) (defaults to enabled)
+- Optional PostgreSQL deployment using the [PostgreSQL Chart](https://github.com/kubernetes/charts/tree/master/stable/postgresql) (defaults to enabled)
+- Optional Ingress (defaults to disabled)
+
+## Prerequisites
+
+- _At least_ 3 GB of RAM available on your cluster, in chunks of 1 GB
+- Kubernetes 1.4+ with Beta APIs enabled
+- [Persistent Volume](https://kubernetes.io/docs/concepts/storage/persistent-volumes/) provisioner support in the underlying infrastructure
+- The ability to point a DNS entry or URL at your GitLab install
+- The `kubectl` CLI installed locally and authenticated for the cluster
+- The Helm Client installed locally
+- The Helm Server (Tiller) already installed and running in the cluster, by running `helm init`
+- The GitLab Helm Repo [added to your Helm Client](index.md#add-the-gitlab-helm-repository)
+
+## Configuring GitLab
+
+Create a `values.yaml` file for your GitLab configuration. See the
+[Helm docs](https://github.com/kubernetes/helm/blob/master/docs/chart_template_guide/values_files.md)
+for information on how your values file will override the defaults.
+
+The default configuration can always be [found in the `values.yaml`](https://gitlab.com/charts/charts.gitlab.io/blob/master/charts/gitlab/values.yaml), in the chart repository.
+
+### Required configuration
+
+In order for GitLab to function, your config file **must** specify the following:
+
+- An `externalUrl` that GitLab will be reachable at.
+
+### Choosing GitLab Edition
+
+The Helm chart defaults to installing GitLab CE. This can be controlled by setting the `edition` variable in your values.
+
+Setting `edition` to GitLab Enterprise Edition (EE) in your `values.yaml`
+
+```yaml
+edition: EE
+
+externalUrl: 'http://gitlab.example.com'
+```
+
+### Choosing a different GitLab release version
+
+The version of GitLab installed is based on the `edition` setting (see [section](#choosing-gitlab-edition) above), and
+the value of the corresponding helm setting: `ceImage` or `eeImage`.
+
+```yaml
+## GitLab Edition
+## ref: https://about.gitlab.com/products/
+## - CE - Community Edition
+## - EE - Enterprise Edition - (requires license issued by GitLab Inc)
+##
+edition: CE
+
+## GitLab CE image
+## ref: https://hub.docker.com/r/gitlab/gitlab-ce/tags/
+##
+ceImage: gitlab/gitlab-ce:9.1.2-ce.0
+
+## GitLab EE image
+## ref: https://hub.docker.com/r/gitlab/gitlab-ee/tags/
+##
+eeImage: gitlab/gitlab-ee:9.1.2-ee.0
+```
+
+The different images can be found in the [gitlab-ce](https://hub.docker.com/r/gitlab/gitlab-ce/tags/) and [gitlab-ee](https://hub.docker.com/r/gitlab/gitlab-ee/tags/)
+repositories on Docker Hub
+
+> **Note:**
+There is no guarantee that other release versions of GitLab, other than what are
+used by default in the chart, will be supported by a chart install.
+
+
+### Custom Omnibus GitLab configuration
+
+In addition to the configuration options provided for GitLab in the Helm Chart, you can also pass any custom configuration
+that is valid for the [Omnibus GitLab Configuration](https://docs.gitlab.com/omnibus/settings/configuration.html).
+
+The setting to pass these values in is `omnibusConfigRuby`. It accepts any valid
+Ruby code that could used in the Omnibus `/etc/gitlab/gitlab.rb` file. In
+Kubernetes, the contents will be stored in a ConfigMap.
+
+Example setting:
+
+```yaml
+omnibusConfigRuby: |
+  unicorn['worker_processes'] = 2;
+  gitlab_rails['trusted_proxies'] = ["10.0.0.0/8","172.16.0.0/12","192.168.0.0/16"];
+```
+
+### Persistent storage
+
+By default, persistent storage is enabled for GitLab and the charts it depends
+on (Redis and PostgreSQL).
+
+Components can have their claim size set from your `values.yaml`, and each
+component allows you to optionally configure the `storageClass` variable so you
+can take advantage of faster drives on your cloud provider.
+
+Basic configuration:
+
+```yaml
+## Enable persistence using Persistent Volume Claims
+## ref: http://kubernetes.io/docs/user-guide/persistent-volumes/
+## ref: https://docs.gitlab.com/ce/install/requirements.html#storage
+##
+persistence:
+  ## This volume persists generated configuration files, keys, and certs.
+  ##
+  gitlabEtc:
+    enabled: true
+    size: 1Gi
+    ## If defined, volume.beta.kubernetes.io/storage-class: <storageClass>
+    ## Default: volume.alpha.kubernetes.io/storage-class: default
+    ##
+    # storageClass:
+    accessMode: ReadWriteOnce
+  ## This volume is used to store git data and other project files.
+  ## ref: https://docs.gitlab.com/omnibus/settings/configuration.html#storing-git-data-in-an-alternative-directory
+  ##
+  gitlabData:
+    enabled: true
+    size: 10Gi
+    ## If defined, volume.beta.kubernetes.io/storage-class: <storageClass>
+    ## Default: volume.alpha.kubernetes.io/storage-class: default
+    ##
+    # storageClass:
+    accessMode: ReadWriteOnce
+  gitlabRegistry:
+    enabled: true
+    size: 10Gi
+    ## If defined, volume.beta.kubernetes.io/storage-class: <storageClass>
+    ## Default: volume.alpha.kubernetes.io/storage-class: default
+    ##
+    # storageClass:
+
+  postgresql:
+    persistence:
+      # storageClass:
+      size: 10Gi
+  ## Configuration values for the Redis dependency.
+  ## ref: https://github.com/kubernetes/charts/blob/master/stable/redis/README.md
+  ##
+  redis:
+    persistence:
+      # storageClass:
+      size: 10Gi
+```
+
+>**Note:**
+You can make use of faster SSD drives by adding a [StorageClass] to your cluster
+and using the `storageClass` setting in the above config to the name of
+your new storage class.
+
+### Routing
+
+By default, the GitLab chart uses a service type of `LoadBalancer` which will
+result in the GitLab service being exposed externally using your cloud provider's
+load balancer.
+
+This field is configurable in your `values.yml` by setting the top-level
+`serviceType` field. See the [Service documentation][kube-srv] for more
+information on the possible values.
+
+#### Ingress routing
+
+Optionally, you can enable the Chart's ingress for use by an ingress controller
+deployed in your cluster.
+
+To enable the ingress, edit its section in your `values.yaml`:
+
+```yaml
+ingress:
+  ## If true, gitlab Ingress will be created
+  ##
+  enabled: true
+
+  ## gitlab Ingress hostnames
+  ## Must be provided if Ingress is enabled
+  ##
+  hosts:
+    - gitlab.example.com
+
+  ## gitlab Ingress annotations
+  ##
+  annotations:
+    kubernetes.io/ingress.class: nginx
+```
+
+You must also provide the list of hosts that the ingress will use. In order for
+you ingress controller to work with the GitLab Ingress, you will need to specify
+its class in an annotation.
+
+>**Note:**
+The Ingress alone doesn't expose GitLab externally. You need to have a Ingress controller setup to do that.
+Setting up an Ingress controller can be as simple as installing the `nginx-ingress` helm chart. But be sure
+to read the [documentation](https://github.com/kubernetes/charts/blob/master/stable/nginx-ingress/README.md)
+
+### External database
+
+You can configure the GitLab Helm chart to connect to an external PostgreSQL
+database.
+
+>**Note:**
+This is currently our recommended approach for a Production setup.
+
+To use an external database, in your `values.yaml`, disable the included
+PostgreSQL dependency, then configure access to your database:
+
+```yaml
+dbHost: "<reachable postgres hostname>"
+dbPassword: "<password for the user with access to the db>"
+dbUsername: "<user with read/write access to the database>"
+dbDatabase: "<database name on postgres to connect to for GitLab>"
+
+postgresql:
+  # Sets whether the PostgreSQL helm chart is used as a dependency
+  enabled: false
+```
+
+Be sure to check the GitLab documentation on how to
+[configure the external database](../requirements.md#postgresql-requirements)
+
+You can also configure the chart to use an external Redis server, but this is
+not required for basic production use:
+
+```yaml
+dbHost: "<reachable redis hostname>"
+dbPassword: "<password>"
+
+redis:
+  # Sets whether the Redis helm chart is used as a dependency
+  enabled: false
+```
+
+### Sending email
+
+By default, the GitLab container will not be able to send email from your cluster.
+In order to send email, you should configure SMTP settings in the
+`omnibusConfigRuby` section, as per the [GitLab Omnibus documentation](https://docs.gitlab.com/omnibus/settings/smtp.html).
+
+>**Note:**
+Some cloud providers restrict emails being sent out on SMTP, so you will have
+to use a SMTP service that is supported by your provider. See this
+[Google Cloud Platform page](https://cloud.google.com/compute/docs/tutorials/sending-mail/)
+as and example.
+
+Here is an example configuration for Mailgun SMTP support:
+
+```yaml
+omnibusConfigRuby: |
+  # This is example config of what you may already have in your omnibusConfigRuby object
+  unicorn['worker_processes'] = 2;
+  gitlab_rails['trusted_proxies'] = ["10.0.0.0/8","172.16.0.0/12","192.168.0.0/16"];
+
+  # SMTP settings
+  gitlab_rails['smtp_enable'] = true
+  gitlab_rails['smtp_address'] = "smtp.mailgun.org"
+  gitlab_rails['smtp_port'] = 2525 # High port needed for Google Cloud
+  gitlab_rails['smtp_authentication'] = "plain"
+  gitlab_rails['smtp_enable_starttls_auto'] = false
+  gitlab_rails['smtp_user_name'] = "postmaster@mg.your-mail-domain"
+  gitlab_rails['smtp_password'] = "you-password"
+  gitlab_rails['smtp_domain'] = "mg.your-mail-domain"
+```
+
+### HTTPS configuration
+
+To setup HTTPS access to your GitLab server, first you need to configure the
+chart to use the [ingress](#ingress-routing).
+
+GitLab's config should be updated to support [proxied SSL](https://docs.gitlab.com/omnibus/settings/nginx.html#supporting-proxied-ssl).
+
+In addition to having a Ingress Controller deployed and the basic ingress
+settings configured, you will also need to specify in the ingress settings
+which hosts to use HTTPS for.
+
+Make sure `externalUrl` now includes `https://` instead of `http://` in its
+value, and update the `omnibusConfigRuby` section:
+
+```yaml
+externalUrl: 'https://gitlab.example.com'
+
+omnibusConfigRuby: |
+  # This is example config of what you may already have in your omnibusConfigRuby object
+  unicorn['worker_processes'] = 2;
+  gitlab_rails['trusted_proxies'] = ["10.0.0.0/8","172.16.0.0/12","192.168.0.0/16"];
+
+  # These are the settings needed to support proxied SSL
+  nginx['listen_port'] = 80
+  nginx['listen_https'] = false
+  nginx['proxy_set_headers'] = {
+    "X-Forwarded-Proto" => "https",
+    "X-Forwarded-Ssl" => "on"
+  }
+
+ingress:
+  enabled: true
+  annotations:
+   kubernetes.io/ingress.class: nginx
+   # kubernetes.io/tls-acme: 'true' Annotation used for letsencrypt support
+
+  hosts:
+    - gitlab.example.com
+
+    ## gitlab Ingress TLS configuration
+    ## Secrets must be created in the namespace, and is not done for you in this chart
+    ##
+    tls:
+      - secretName: gitlab-tls
+        hosts:
+          - gitlab.example.com
+```
+
+You will need to create the named secret in your cluster, specifying the private
+and public certificate pair using the format outlined in the
+[ingress documentation](https://kubernetes.io/docs/concepts/services-networking/ingress/#tls).
+
+Alternatively, you can use the `kubernetes.io/tls-acme` annotation, and install
+the `kube-lego` chart to your cluster to have Let's Encrypt issue your
+certificate. See the [kube-lego documentation](https://github.com/kubernetes/charts/blob/master/stable/kube-lego/README.md)
+for more information.
+
+### Enabling the GitLab Container Registry
+
+The GitLab Registry is disabled by default but can be enabled by providing an
+external URL for it in the configuration. In order for the Registry to be easily
+used by GitLab CI and your Kubernetes cluster, you will need to set it up with
+a TLS certificate, so these examples will include the ingress settings for that
+as well. See the [HTTPS Configuration section](#https-configuration)
+for more explanation on some of these settings.
+
+Example config:
+
+```yaml
+externalUrl: 'https://gitlab.example.com'
+
+omnibusConfigRuby: |
+  # This is example config of what you may already have in your omnibusConfigRuby object
+  unicorn['worker_processes'] = 2;
+  gitlab_rails['trusted_proxies'] = ["10.0.0.0/8","172.16.0.0/12","192.168.0.0/16"];
+
+  registry_external_url 'https://registry.example.com';
+
+  # These are the settings needed to support proxied SSL
+  nginx['listen_port'] = 80
+  nginx['listen_https'] = false
+  nginx['proxy_set_headers'] = {
+    "X-Forwarded-Proto" => "https",
+    "X-Forwarded-Ssl" => "on"
+  }
+  registry_nginx['listen_port'] = 80
+  registry_nginx['listen_https'] = false
+  registry_nginx['proxy_set_headers'] = {
+    "X-Forwarded-Proto" => "https",
+    "X-Forwarded-Ssl" => "on"
+  }
+
+ingress:
+  enabled: true
+  annotations:
+   kubernetes.io/ingress.class: nginx
+   # kubernetes.io/tls-acme: 'true' Annotation used for letsencrypt support
+
+  hosts:
+    - gitlab.example.com
+    - registry.example.com
+
+    ## gitlab Ingress TLS configuration
+    ## Secrets must be created in the namespace, and is not done for you in this chart
+    ##
+    tls:
+      - secretName: gitlab-tls
+        hosts:
+          - gitlab.example.com
+          - registry.example.com
+```
+

+# GitLab Runner Helm Chart
+
+The `gitlab-runner` Helm chart deploys a GitLab Runner instance into your
+Kubernetes cluster.
+
+This chart configures the Runner to:
+
+- Run using the GitLab Runner [Kubernetes executor](https://docs.gitlab.com/runner/install/kubernetes.html)
+- For each new job it receives from [GitLab CI](https://about.gitlab.com/features/gitlab-ci-cd/), it will provision a
+  new pod within the specified namespace to run it.
+
+## Prerequisites
+
+- Your GitLab Server's API is reachable from the cluster
+- Kubernetes 1.4+ with Beta APIs enabled
+- The `kubectl` CLI installed locally and authenticated for the cluster
+- The Helm Client installed locally
+- The Helm Server (Tiller) already installed and running in the cluster, by running `helm init`
+- The GitLab Helm Repo added to your Helm Client. See [Adding GitLab Helm Repo](index.md#add-the-gitlab-helm-repository)
+
+## Configuring GitLab Runner using the Helm Chart
+
+Create a `values.yaml` file for your GitLab Runner configuration. See [Helm docs](https://github.com/kubernetes/helm/blob/master/docs/chart_template_guide/values_files.md)
+for information on how your values file will override the defaults.
+
+The default configuration can always be found in the [values.yaml](https://gitlab.com/charts/charts.gitlab.io/blob/master/charts/gitlab-runner/values.yaml) in the chart repository.
+
+### Required configuration
+
+In order for GitLab Runner to function, your config file **must** specify the following:
+
+ - `gitlabURL`  - the GitLab Server URL (with protocol) to register the runner against
+ - `runnerRegistrationToken` - The Registration Token for adding new Runners to the GitLab Server. This must be
+    retrieved from your GitLab Instance. See the [GitLab Runner Documentation](../../ci/runners/README.md#creating-and-registering-a-runner) for more information.
+
+### Other configuration
+
+The rest of the configuration is [documented in the `values.yaml`](https://gitlab.com/charts/charts.gitlab.io/blob/master/charts/gitlab-runner/values.yaml) in the chart repository.
+
+Here is a snippet of the important settings:
+
+```yaml
+## The GitLab Server URL (with protocol) that want to register the runner against
+## ref: https://docs.gitlab.com/runner/commands/README.html#gitlab-runner-register
+##
+gitlabURL: http://gitlab.your-domain.com/
+
+## The Registration Token for adding new Runners to the GitLab Server. This must
+## be retreived from your GitLab Instance.
+## ref: https://docs.gitlab.com/ce/ci/runners/README.html#creating-and-registering-a-runner
+##
+runnerRegistrationToken: ""

+
+## Defines in seconds how often to check GitLab for a new builds
+## ref: https://docs.gitlab.com/runner/configuration/advanced-configuration.html#the-global-section
+##
+checkInterval: 30
+
+## Configuration for the Pods that that the runner launches for each new job
+##
+runners:
+  ## Default container image to use for builds when none is specified
+  ##
+  image: ubuntu:16.04
+
+  ## Run all containers with the privileged flag enabled

+  privileged: false
+
+  ## Namespace to run Kubernetes jobs in (defaults to 'default')
+  ##

+  ##
+  builds:
+    # cpuLimit: 200m
+    # memoryLimit: 256Mi
+    cpuRequests: 100m
+    memoryRequests: 128Mi
+
+  ## Service Container specific configuration
+  ##

+    # cpuLimit: 200m
+    # memoryLimit: 256Mi
+    cpuRequests: 100m
+    memoryRequests: 128Mi
+
+```
+
+### Running Docker-in-Docker containers with GitLab Runners
+
+See [Running Privileged Containers for the Runners](#running-privileged-containers-for-the-runners) for how to enable it,
+and the [GitLab CI Runner documentation](https://docs.gitlab.com/runner/executors/kubernetes.html#using-docker-in-your-builds) on running dind.
+
+### Running privileged containers for the Runners
+
+You can tell the GitLab Runner to run using privileged containers. You may need
+this enabled if you need to use the Docker executable within your GitLab CI jobs.
+
+This comes with several risks that you can read about in the
+[GitLab CI Runner documentation](https://docs.gitlab.com/runner/executors/kubernetes.html#using-docker-in-your-builds).
+
+If you are okay with the risks, and your GitLab CI Runner instance is registered
+against a specific project in GitLab that you trust the CI jobs of, you can
+enable privileged mode in `values.yaml`:
+
+```yaml
+runners:
+  ## Run all containers with the privileged flag enabled
+  ## This will allow the docker:dind image to run if you need to run Docker
+  ## commands. Please read the docs before turning this on:
+  ## ref: https://docs.gitlab.com/runner/executors/kubernetes.html#using-docker-dind
+  ##
+  privileged: true
+```
+
+## Installing GitLab Runner using the Helm Chart
+
+Once you [have configured](#configuration) GitLab Runner in your `values.yml` file,
+run the following:
+
+```bash
+helm install --namepace <NAMEPACE> --name gitlab-runner -f <CONFIG_VALUES_FILE> gitlab/gitlab-runner
+```
+
+- `<NAMESPACE>` is the Kubernetes namespace where you want to install the GitLab Runner.
+- `<CONFIG_VALUES_FILE>` is the path to values file containing your custom configuration. See the
+  [Configuration](#configuration) section to create it.
+
+## Updating GitLab Runner using the Helm Chart
+
+Once your GitLab Runner Chart is installed, configuration changes and chart updates should we done using `helm upgrade`
+
+```bash
+helm upgrade --namepace <NAMEPACE> -f <CONFIG_VALUES_FILE> <RELEASE-NAME> gitlab/gitlab-runner
+```
+
+Where:
+- `<NAMESPACE>` is the Kubernetes namespace where GitLab Runner is installed
+- `<CONFIG_VALUES_FILE>` is the path to values file containing your custom configuration. See the
+  [Configuration](#configuration) section to create it.
+- `<RELEASE-NAME>` is the name you gave the chart when installing it.
+  In the [Install section](#installing) we called it `gitlab-runner`.
+
+## Uninstalling GitLab Runner using the Helm Chart
+
+To uninstall the GitLab Runner Chart, run the following:
+
+```bash
+helm delete --namespace <NAMESPACE> <RELEASE-NAME>
+```
+
+where:
+
+- `<NAMESPACE>` is the Kubernetes namespace where GitLab Runner is installed

+# Installing GitLab in Kubernetes
+
+The easiest method to deploy GitLab in [Kubernetes](https://kubernetes.io/) is
+to take advantage of the official GitLab Helm charts. [Helm] is a package
+management tool for Kubernetes, allowing apps to be easily managed via their
+Charts. A [Chart] is a detailed description of the application including how it
+should be deployed, upgraded, and configured.
+
+The GitLab Helm repository is located at https://charts.gitlab.io.
+You can report any issues related to GitLab's Helm Charts at
+https://gitlab.com/charts/charts.gitlab.io/issues.
+Contributions and improvements are also very welcome.
+
+## Prerequisites
+
+To use the charts, the Helm tool must be installed and initialized. The best
+place to start is by reviewing the [Helm Quick Start Guide][helm-quick].
+
+## Add the GitLab Helm repository
+
+Once Helm has been installed, the GitLab chart repository must be added:
+
+```bash
+helm repo add gitlab https://charts.gitlab.io
+```
+
+After adding the repository, Helm must be re-initialized:
+
+```bash
+helm init
+```
+
+## Using the GitLab Helm Charts
+
+GitLab makes available two Helm Charts, one for the GitLab server and another
+for the Runner. More detailed information on installing and configuring each
+Chart can be found below:

-Chat commands allow user to perform common operations on GitLab right from there chat client.
-Right now both Mattermost and Slack are supported.
+Chat commands in Mattermost and Slack (also called Slack slash commands) allow you to control GitLab and view GitLab content right inside your chat client, without having to leave it. For Slack, this requires a [project service configuration](../user/project/integrations/slack_slash_commands.md). Simply type the command as a message in your chat client to activate it.

+# From 9.1 to 9.2
+
+Make sure you view this update guide from the tag (version) of GitLab you would
+like to install. In most cases this should be the highest numbered production
+tag (without rc in it). You can select the tag in the version dropdown at the
+top left corner of GitLab (below the menu bar).
+
+If the highest number stable branch is unclear please check the
+[GitLab Blog](https://about.gitlab.com/blog/archives.html) for installation
+guide links by version.
+
+### 1. Stop server
+
+```bash
+sudo service gitlab stop
+```
+
+### 2. Backup
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H bundle exec rake gitlab:backup:create RAILS_ENV=production
+```
+
+### 3. Update Ruby
+
+NOTE: GitLab 9.0 and higher only support Ruby 2.3.x and dropped support for Ruby 2.1.x. Be
+sure to upgrade your interpreter if necessary.
+
+You can check which version you are running with `ruby -v`.
+
+Download and compile Ruby:
+
+```bash
+mkdir /tmp/ruby && cd /tmp/ruby
+curl --remote-name --progress https://cache.ruby-lang.org/pub/ruby/2.3/ruby-2.3.3.tar.gz
+echo '1014ee699071aa2ddd501907d18cbe15399c997d ruby-2.3.3.tar.gz' | shasum -c - && tar xzf ruby-2.3.3.tar.gz
+cd ruby-2.3.3
+./configure --disable-install-rdoc
+make
+sudo make install
+```
+
+Install Bundler:
+
+```bash
+sudo gem install bundler --no-ri --no-rdoc
+```
+
+### 4. Update Node
+
+GitLab now runs [webpack](http://webpack.js.org) to compile frontend assets and
+it has a minimum requirement of node v4.3.0.
+
+You can check which version you are running with `node -v`. If you are running
+a version older than `v4.3.0` you will need to update to a newer version.  You
+can find instructions to install from community maintained packages or compile
+from source at the nodejs.org website.
+
+<https://nodejs.org/en/download/>
+
+
+Since 8.17, GitLab requires the use of yarn `>= v0.17.0` to manage
+JavaScript dependencies.
+
+```bash
+curl --location https://yarnpkg.com/install.sh | bash -
+```
+
+More information can be found on the [yarn website](https://yarnpkg.com/en/docs/install).
+
+### 5. Get latest code
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H git fetch --all
+sudo -u git -H git checkout -- db/schema.rb # local changes will be restored automatically
+```
+
+For GitLab Community Edition:
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H git checkout 9-2-stable
+```
+
+OR
+
+For GitLab Enterprise Edition:
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H git checkout 9-2-stable-ee
+```
+
+### 6. Update gitlab-shell
+
+```bash
+cd /home/git/gitlab-shell
+
+sudo -u git -H git fetch --all --tags
+sudo -u git -H git checkout v$(</home/git/gitlab/GITLAB_SHELL_VERSION)
+sudo -u git -H bin/compile
+```
+
+### 7. Update gitlab-workhorse
+
+Install and compile gitlab-workhorse. This requires
+[Go 1.5](https://golang.org/dl) which should already be on your system from
+GitLab 8.1. GitLab-Workhorse uses [GNU Make](https://www.gnu.org/software/make/).
+If you are not using Linux you may have to run `gmake` instead of
+`make` below.
+
+```bash
+cd /home/git/gitlab-workhorse
+
+sudo -u git -H git fetch --all --tags
+sudo -u git -H git checkout v$(</home/git/gitlab/GITLAB_WORKHORSE_VERSION)
+sudo -u git -H make
+```
+
+### 8. Update configuration files
+
+#### New configuration options for `gitlab.yml`
+
+There might be configuration options available for [`gitlab.yml`][yaml]. View them with the command below and apply them manually to your current `gitlab.yml`:
+
+```sh
+cd /home/git/gitlab
+
+git diff origin/9-1-stable:config/gitlab.yml.example origin/9-2-stable:config/gitlab.yml.example
+```
+
+#### Nginx configuration
+
+Ensure you're still up-to-date with the latest NGINX configuration changes:
+
+```sh
+cd /home/git/gitlab
+
+# For HTTPS configurations
+git diff origin/9-1-stable:lib/support/nginx/gitlab-ssl origin/9-2-stable:lib/support/nginx/gitlab-ssl
+
+# For HTTP configurations
+git diff origin/9-1-stable:lib/support/nginx/gitlab origin/9-2-stable:lib/support/nginx/gitlab
+```
+
+If you are using Strict-Transport-Security in your installation to continue using it you must enable it in your Nginx
+configuration as GitLab application no longer handles setting it.
+
+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/9-2-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/9-1-stable/config/initializers/smtp_settings.rb.sample#L13
+
+#### Init script
+
+There might be new configuration options available for [`gitlab.default.example`][gl-example]. View them with the command below and apply them manually to your current `/etc/default/gitlab`:
+
+```sh
+cd /home/git/gitlab
+
+git diff origin/9-1-stable:lib/support/init.d/gitlab.default.example origin/9-2-stable:lib/support/init.d/gitlab.default.example
+```
+
+Ensure you're still up-to-date with the latest init script changes:
+
+```bash
+cd /home/git/gitlab
+
+sudo cp lib/support/init.d/gitlab /etc/init.d/gitlab
+```
+
+For Ubuntu 16.04.1 LTS:
+
+```bash
+sudo systemctl daemon-reload
+```
+
+### 9. Install libs, migrations, etc.
+
+```bash
+cd /home/git/gitlab
+
+# MySQL installations (note: the line below states '--without postgres')
+sudo -u git -H bundle install --without postgres development test --deployment
+
+# PostgreSQL installations (note: the line below states '--without mysql')
+sudo -u git -H bundle install --without mysql development test --deployment
+
+# Optional: clean up old gems
+sudo -u git -H bundle clean
+
+# Run database migrations
+sudo -u git -H bundle exec rake db:migrate RAILS_ENV=production
+
+# Update node dependencies and recompile assets
+sudo -u git -H bundle exec rake yarn:install gitlab:assets:clean gitlab:assets:compile RAILS_ENV=production NODE_ENV=production
+
+# Clean up cache
+sudo -u git -H bundle exec rake cache:clear RAILS_ENV=production
+```
+
+**MySQL installations**: Run through the `MySQL strings limits` and `Tables and data conversion to utf8mb4` [tasks](../install/database_mysql.md).
+
+### 10. Optional: install Gitaly
+
+Gitaly is still an optional component of GitLab. If you want to save time
+during your 9.2 upgrade **you can skip this step**.
+
+If you have not yet set up Gitaly then follow [Gitaly section of the installation
+guide](../install/installation.md#install-gitaly).
+
+#### Compile Gitaly
+
+```shell
+cd /home/git/gitaly
+sudo -u git -H git fetch --all --tags
+sudo -u git -H git checkout v$(</home/git/gitlab/GITALY_SERVER_VERSION)
+sudo -u git -H make
+```
+
+### 11. Start application
+
+```bash
+sudo service gitlab start
+sudo service nginx restart
+```
+
+### 12. Check application status
+
+Check if GitLab and its environment are configured correctly:
+
+```bash
+cd /home/git/gitlab
+
+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:
+
+```bash
+cd /home/git/gitlab
+
+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 (9.1)
+
+### 1. Revert the code to the previous version
+
+Follow the [upgrade guide from 9.0 to 9.1](9.0-to-9.1.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.

 # Slack Notifications Service
 
-## On Slack
+The Slack Notifications Service allows your GitLab project to send events (e.g. issue created) to your existing Slack team as notifications. This requires configurations in both Slack and GitLab.
 
-To enable Slack integration you must create an incoming webhook integration on
-Slack:
+> Note: You can also use Slack slash commands to control GitLab inside Slack. This is the separately configured [Slack slash commands](slack_slash_commands.md).
 
-1. [Sign in to Slack](https://slack.com/signin)
-1. Visit [Incoming WebHooks](https://my.slack.com/services/new/incoming-webhook/)
-1. Choose the channel name you want to send notifications to.
-1. Click **Add Incoming WebHooks Integration**
-1. Copy the **Webhook URL**, we'll need this later for GitLab.
+## Slack Configuration
 
-## On GitLab
+1. Sign in to your Slack team and [start a new Incoming WebHooks configuration](https://my.slack.com/services/new/incoming-webhook/).
+1. Select the Slack channel where notifications will be sent to by default. Click the **Add Incoming WebHooks integration** button to add the configuration.
+1. Copy the **Webhook URL**, which we'll use later in the GitLab configuration.
 
-After you set up Slack, it's time to set up GitLab.
+## GitLab Configuration
 
-Navigate to the [Integrations page](project_services.md#accessing-the-project-services)
-and select the **Slack notifications** service to configure it.
-There, you will see a checkbox with the following events that can be triggered:
+1. Navigate to the [Integrations page](project_services.md#accessing-the-project-services) in your project's settings, i.e. **Project > Settings > Integrations**.
+1. Select the **Slack notifications** project service to configure it.
+1. Check the **Active** checkbox to turn on the service.
+1. Check the checkboxes corresponding to the GitLab events you want to send to Slack as a notification.
+1. For each event, optionally enter the Slack channel where you want to send the event. (Do _not_ include the `#` symbol.) If left empty, the event will be sent to the default channel that you configured in the Slack Configuration step.
+1. Paste the **Webhook URL** that you copied from the Slack Configuration step.
+1. Optionally customize the Slack bot username that will be sending the notifications.
+1. Configure the remaining options and click `Save changes`.
 
-- Push
-- Issue
-- Confidential issue
-- Merge request
-- Note
-- Tag push
-- Pipeline
-- Wiki page
+Your Slack team will now start receiving GitLab event notifications as configured.
 
-Below each of these event checkboxes, you have an input field to enter
-which Slack channel you want to send that event message. Enter your preferred channel name **without** the hash sign (`#`).
-
-At the end, fill in your Slack details:
-
-| Field | Description |
-| ----- | ----------- |
-| **Webhook**  | The [incoming webhook URL][slackhook] which you have to setup on Slack. |
-| **Username** | Optional username which can be on messages sent to Slack. Fill this in if you want to change the username of the bot. |
-| **Notify only broken pipelines** | If you choose to enable the **Pipeline** event and you want to be only notified about failed pipelines. |

 > Introduced in GitLab 8.15
 
-Slack commands give users an extra interface to perform common operations
-from the chat environment. This allows one to, for example, create an issue as
-soon as the idea was discussed in chat.
-For all available commands try the help subcommand, for example: `/gitlab help`,
-all review the [full list of commands](../../../integration/chat_commands.md).
+Slack slash commands (also known as chat commmands) allow you to control GitLab and view content right inside Slack, without having to leave it. This requires configurations in both Slack and GitLab. 
 
-## Prerequisites
-
-A [team](https://get.slack.help/hc/en-us/articles/217608418-Creating-a-team) in
-Slack should be created beforehand, GitLab cannot create it for you.
+> Note: GitLab can also send events (e.g. issue created) to Slack as notifications. This is the separately configured [Slack Notifications Service](slack.md).
 
 ## Configuration
 
-Go to your project's [Integrations page](project_services.md#accessing-the-project-services)
-and select the **Slack slash commands** service to configure it.
+1. Slack slash commands are scoped to a project. Navigate to the [Integrations page](project_services.md#accessing-the-project-services) in your project's settings, i.e. **Project > Settings > Integrations**.
+1. Select the **Slack slash commands** project service to configure it. This page contains required information to complete the configuration in Slack. Leave this browser tab open.
+1. Open a new browser tab and sign in to your Slack team. [Start a new Slash Commands integration](https://my.slack.com/services/new/slash-commands).
+1. Enter a trigger term. We suggest you use the project name. Click **Add Slash Command Integration**.
+1. Complete the rest of the fields in the Slack configuration page using information from the GitLab browser tab. In particular, the URL needs to be copied and pasted. Click **Save Integration** to complete the configuration in Slack.
+1. While still on the Slack configuration page, copy the **token**. Go back to the GitLab browser tab and paste in the **token**.
+1. Check the **Active** checkbox and click **Save changes** to complete the configuration in GitLab.
 
 ![Slack setup instructions](img/slack_setup.png)
 
-Once you've followed the instructions, mark the service as active and insert the token
-you've received from Slack. After saving the service you are good to go!
+## Usage
+
+You can now use the [Slack slash commands](../../../integration/chat_commands.md).

+# Closing Issues
+
+Please read through the [GitLab Issue Documentation](index.md) for an overview on GitLab Issues.
+
+## Directly
+
+Whenever you decide that's no longer need for that issue,
+close the issue using the close button:
+
+![close issue - button](img/button_close_issue.png)
+
+## Via Merge Request
+
+When a merge request resolves the discussion over an issue, you can
+make it close that issue(s) when merged.
+
+All you need is to use a [keyword](automatic_issue_closing.md)
+accompanying the issue number, add to the description of that MR.
+
+In this example, the keyword "closes" prefixing the issue number will create a relationship
+in such a way that the merge request will close the issue when merged. 
+
+Mentioning various issues in the same line also works for this purpose:
+
+```md
+Closes #333, #444, #555 and #666
+```
+
+If the issue is in a different repository rather then the MR's,
+add the full URL for that issue(s):
+
+```md
+Closes #333, #444, and https://gitlab.com/<username>/<projectname>/issues/<xxx>
+```
+
+All the following keywords will produce the same behaviour:
+
+- Close, Closes, Closed, Closing, close, closes, closed, closing
+- Fix, Fixes, Fixed, Fixing, fix, fixes, fixed, fixing
+- Resolve, Resolves, Resolved, Resolving, resolve, resolves, resolved, resolving
+
+![merge request closing issue when merged](img/merge_request_closes_issue.png)
+
+If you use any other word before the issue number, the issue and the MR will
+link to each other, but the MR will NOT close the issue(s) when merged.
+
+![mention issues in MRs - closing and related](img/closing_and_related_issues.png)
+
+## From the Issue Board
+
+You can close an issue from [Issue Boards](../issue_board.md) by draging an issue card
+from its list and dropping into **Closed**.
+
+![close issue from the Issue Board](img/close_issue_from_board.gif)
+
+## Customizing the issue closing patern
+
+Alternatively, a GitLab **administrator** can
+[customize the issue closing patern](../../../administration/issue_closing_pattern.md).

+# Crosslinking Issues
+
+Please read through the [GitLab Issue Documentation](index.md) for an overview on GitLab Issues.
+
+## From Commit Messages
+
+Every time you mention an issue in your commit message, you're creating
+a relationship between the two stages of the development workflow: the
+issue itself and the first commit related to that issue.
+
+If the issue and the code you're committing are both in the same project,
+you simply add `#xxx` to the commit message, where `xxx` is the issue number.
+If they are not in the same project, you can add the full URL to the issue
+(`https://gitlab.com/<username>/<projectname>/issues/<xxx>`).
+
+```shell
+git commit -m "this is my commit message. Ref #xxx"
+```
+
+or
+
+```shell
+git commit -m "this is my commit message. Related to https://gitlab.com/<username>/<projectname>/issues/<xxx>"
+```
+
+Of course, you can replace `gitlab.com` with the URL of your own GitLab instance.
+
+**Note:** Linking your first commit to your issue is going to be relevant
+for tracking your process far ahead with
+[GitLab Cycle Analytics](https://about.gitlab.com/features/cycle-analytics/)).
+It will measure the time taken for planning the implementation of that issue,
+which is the time between creating an issue and making the first commit.
+
+## From Related Issues
+
+Mentioning related issues in merge requests and other issues is useful
+for your team members and collaborators to know that there are opened
+issues around that same idea.
+
+You do that as explained above, when
+[mentioning an issue from a commit message](#from-commit-messages).
+
+When mentioning the issue "A" in a issue "B", the issue "A" will also
+display a notification in its tracker. The same is valid for mentioning
+issues in merge requests.
+
+![issue mentioned in issue](img/mention_in_issue.png)
+
+## From Merge Requests
+
+Mentioning issues in merge request comments work exactly the same way
+they do for [related issues](#from-related-issues). 
+
+When you mention an issue in a merge request description, you can either
+[close the issue as soon as the merge request is merged](closing_issues.md#via-merge-request),
+or simply link both issue and merge request as described in the
+[closing issues documentation](closing_issues.md#from-related-issues).
+
+![issue mentioned in MR](img/mention_in_merge_request.png)
+
+### Close an issue by merging a merge request
+
+To [close an issue when a merge request is merged](closing_issues.md#via-merge-request), use the [automatic issue closing patern](automatic_issue_closing.md).

+# GitLab Issues Documentation
+
+The GitLab Issue Tracker is an advanced and complete tool
+for tracking the evolution of a new idea or the process
+of solving a problem.
+
+It allows you, your team, and your collaborators to share
+and discuss proposals, before and while implementing them.
+
+Issues and the GitLab Issue Tracker are available in all
+[GitLab Products](https://about.gitlab.com/products/) as
+part of the [GitLab Workflow](https://about.gitlab.com/2016/10/25/gitlab-workflow-an-overview/).
+
+## Use-Cases
+
+Issues can have endless applications. Just to exemplify, these are
+some cases for which creating issues are most used:
+
+- Discussing the implementation of a new idea
+- Submitting feature proposals
+- Asking questions
+- Reporting bugs and malfunction
+- Obtaining support
+- Elaborating new code implementations
+
+See also the blog post [Always start a discussion with an issue](https://about.gitlab.com/2016/03/03/start-with-an-issue/).
+
+## Issue Tracker
+
+The issue tracker is the collection of opened and closed issues created in a project.
+
+![Issue tracker](img/issue_tracker.png)
+
+Find the issue tracker by navigating to your **Project's Dashboard** > **Issues**.
+
+## GitLab Issues Functionalities
+
+The image bellow illustrates how an issue looks like:
+
+![Issue view](img/issues_main_view.png)
+
+Learn more about it on the [GitLab Issues Functionalities documentation](issues_functionalities.md).
+
+## New Issue
+
+Read through the [documentation on creating issues](create_new_issue.md).
+
+## Closing issues
+
+Read through the distinct ways to [close issues](closing_issues.md) on GitLab.
+
+## Search for an issue
+
+Learn how to [find an issue](../../search/index.md) by searching for and filtering them.
+
+## Advanced features
+
+### Confidential Issues
+
+Whenever you want to keep the discussion presented in a

+# GitLab Issues Functionalities
+
+Please read through the [GitLab Issue Documentation](index.md) for an overview on GitLab Issues.
+
+## Issues Functionalities
+
+The image bellow illustrates how an issue looks like:
+
+![Issue view](img/issues_main_view_numbered.png)
+
+You can find all the information on that issue on one screen.
+
+### Issue screen
+
+An issue starts with its status (open or closed), followed by its author,
+and includes many other functionalities, numbered on the image above to
+explain what they mean, one by one.
+
+#### 1. New Issue, close issue, edit
+
+- New issue: create a new issue in the same project
+- Close issue: close this issue
+- Edit: edit the same fields available when you create an issue.
+
+#### 2. Todos
+
+- Add todo: add that issue to your [GitLab Todo](../../../workflow/todos.html) list
+- Mark done: mark that issue as done (reflects on the Todo list)
+
+#### 3. Assignee
+
+Whenever someone starts to work on an issue, it can be assigned
+to that person. The assignee can be changed as much as needed.
+The idea is that the assignee is responsible for that issue until
+it's reassigned to someone else to take it from there.
+
+> **Tip:**
+if a user is not member of that project, it can only be
+assigned to them if they created the issue themselves.
+
+#### 4. Milestone
+
+- Select a [milestone](../milestones/index.md) to attribute that issue to.
+
+#### 5. Time Tracking (EES/EEP)
+
+This feature is available only in [GitLab Enterprise Edition](https://about.gitlab.com/gitlab-ee/).
+
+- Estimate time: add an estimate time in which the issue will be implemented
+- Spend: add the time spent on the implementation of that issue
+
+> **Note:**
+both estimate and spend times are set via [GitLab Slash Commands](../slash_commands.md).
+
+Learn more on the [Time Tracking documentation](https://docs.gitlab.com/ee/workflow/time_tracking.html).
+
+#### 6. Due date
+
+When you work on a tight schedule, and it's important to
+have a way to setup a deadline for implementations and for solving
+problems. This can be facilitated by the [due date](due_dates.md)). Due dates
+can be changed as many times as needed.
+
+#### 7. Labels
+
+Categorize issues by giving them [labels](../labels.md). They help to
+organize team's workflows, once they enable you to work with the
+[GitLab Issue Board](index.md#gitlab-issue-board).
+
+Group Labels, which allow you to use the same labels per
+group of projects, can be also given to issues. They work exactly the same,
+but they are immediately available to all projects in the group.
+
+> **Tip:**
+if the label doesn't exist yet, when you click **Edit**, it opens a dropdown menu from which you can select **Create new label**.
+
+#### 8. Weight (EES/EEP)
+
+Issue Weights are only available in [GitLab Enterprise Edition](https://about.gitlab.com/gitlab-ee/).
+
+- Attribute a weight (in a 0 to 9 range) to that issue. Easy to complete
+should weight 1 and very hard to complete should weight 9.
+
+Learn more on the [Issue Weight documentation](https://docs.gitlab.com/ee/workflow/issue_weight.html).
+
+#### 9. Participants
+
+- People involved in that issue (mentioned in the description or in the [discussion](../../discussions/index.md)).
+
+#### 10. Notifications
+
+- Subscribe: if you are not a participant of the discussion on that issue, but
+want to receive notifications on each new input, subscribe to it.
+- Unsubscribe: if you are receiving notifications on that issue but no
+longer want to receive them, unsubscribe to it.
+
+Read more on the [notifications documentation](../../../workflow/notifications.md#issue-merge-request-events).
+
+#### 11. Reference
+
+- A quick "copy to clipboard" button to that issue's reference, `foo/bar#xxx`, where `foo` is the `username` or `groupname`, `bar`
+is the `project-name`, and `xxx` is the issue number.
+
+#### 12. Title and description
+
+- Title: a plain text title describing the issue's subject.
+- Description: a text field which fully supports [GitLab Flavored Markdown](../../markdown.md#gitlab-flavored-markdown-gfm).
+
+#### 13. @mentions
+
+- Mentions: you can either `@mention` a user or a group present in your
+GitLab instance and they will be notified via todos and email, unless that
+person has disabled all notifications in their profile settings.
+
+To change your [notification settings](../../../workflow/notifications.md) navigate to
+**Profile Settings** > **Notifications** > **Global notification level**
+and choose your preferences from the dropdown menu.
+
+> **Tip:**
+Avoid mentioning `@all` in issues and merge requests,
+as it sends an email notification
+to all the members of that project's group, which can be
+interpreted as spam.
+
+#### 14. Related Merge Requests
+
+- Any merge requests mentioned in that issue's description
+or in the issue thread.
+
+#### 15. Award emoji
+
+- Award an emoji to that issue. 
+
+> **Tip:**
+Posting "+1" as comments in threads spam all
+participants of that issue. Awarding an emoji is a way to let them
+know you like it without spamming them.
+
+#### 16. Thread
+
+- Comments: collaborate to that issue by posting comments in its thread.
+These text fields also fully support
+[GitLab Flavored Markdown](../../markdown.md#gitlab-flavored-markdown-gfm).
+
+#### 17. Comment, start a discusion, or comment and close
+
+Once you wrote your comment, you can either:
+
+- Click "Comment" and your comment will be published.
+- Click "Start discussion": start a thread within that issue's thread to discuss specific points.
+- Click "Comment and close issue": post your comment and close that issue in one click.
+
+#### 18. New branch
+
+- [New branch](../repository/web_editor.md#create-a-new-branch-from-an-issue):
+create a new branch, followed by a new merge request which will automatically close that
+issue as soon as that merge request is merged.
+
+#### 19. New merge request
+
+- Create a new merge request (with source branch) in one action. Optionally just create a new branch, as explained above.
+

+# Wiki
+
+A separate system for documentation called Wiki, is built right into each
+GitLab project. It is enabled by default on all new projects and you can find
+it under **Wiki** in your project.
+
+Wikis are very convenient if you don't want to keep you documentation in your
+repository, but you do want to keep it in the same project where your code
+resides.
+
+You can create Wiki pages in the web interface or
+[locally using Git](#adding-and-editing-wiki-pages-locally) since every Wiki is
+a separate Git repository.
+
+>**Note:**
+A [permission level][permissions] of **Guest** is needed to view a Wiki and
+**Developer** is needed to create and edit Wiki pages.
+
+## First time creating the Home page
+
+The first time you visit a Wiki, you will be directed to create the Home page.
+The Home page is necessary to be created since it serves as the landing page
+when viewing a Wiki. You only have to fill in the **Content** section and click
+**Create page**. You can always edit it later, so go ahead and write a welcome
+message.
+
+![New home page](img/wiki_create_home_page.png)
+
+## Creating a new wiki page
+
+Create a new page by clicking the **New page** button that can be found
+in all wiki pages. You will be asked to fill in the page name from which GitLab
+will create the path to the page. You can specify a full path for the new file
+and any missing directories will be created automatically.
+
+![New page modal](img/wiki_create_new_page_modal.png)
+
+Once you enter the page name, it's time to fill in its content. GitLab wikis
+support Markdown, RDoc and AsciiDoc. For Markdown based pages, all the
+[Markdown features](../../markdown.md) are supported and for links there is
+some [wiki specific](../../markdown.md#wiki-specific-markdown) behavior.
+
+>**Note:**
+The wiki is based on a Git repository and contains only text files. Uploading
+files via the web interface will upload them in GitLab itself, and they will
+not be available if you clone the wiki repo locally.
+
+In the web interface the commit message is optional, but the GitLab Wiki is
+based on Git and needs a commit message, so one will be created for you if you
+do not enter one.
+
+When you're ready, click the **Create page** and the new page will be created.
+
+![New page](img/wiki_create_new_page.png)
+
+## Editing a wiki page
+
+To edit a page, simply click on the **Edit** button. From there on, you can
+change its content. When done, click **Save changes** for the changes to take
+effect.
+
+## Deleting a wiki page
+
+You can find the **Delete** button only when editing a page. Click on it and
+confirm you want the page to be deleted.
+
+## Viewing a list of all created wiki pages
+
+Every wiki has a sidebar from which a short list of the created pages can be
+found. The list is ordered alphabetically.
+
+![Wiki sidebar](img/wiki_sidebar.png)
+
+If you have many pages, not all will be listed in the sidebar. Click on
+**More pages** to see all of them.
+
+## Viewing the history of a wiki page
+
+The changes of a wiki page over time are recorded in the wiki's Git repository,
+and you can view them by clicking the **Page history** button.
+
+From the history page you can see the revision of the page (Git commit SHA), its
+author, the commit message, when it was last updated and the page markup format.
+To see how a previous version of the page looked like, click on a revision
+number.
+
+![Wiki page history](img/wiki_page_history.png)
+
+## Adding and editing wiki pages locally
+
+Since wikis are based on Git repositories, you can clone them locally and edit
+them like you would do with every other Git repository.
+
+On the right sidebar, click on **Clone repository** and follow the on-screen
+instructions.
