+# Configuration files Documentation
+
+Note that most configuration files (`config/*.*`) committed into
+[gitlab-ce](https://gitlab.com/gitlab-org/gitlab-ce) **will not be used** for
+[omnibus-gitlab](https://gitlab.com/gitlab-org/omnibus-gitlab). Configuration
+files committed into gitlab-ce are only used for development.
+
+## gitlab.yml
+
+You can find most of GitLab configuration settings here.
+
+## mail_room.yml
+
+This file is actually an YML wrapped inside an ERB file to enable templated
+values to be specified from `gitlab.yml`. mail_room loads this file first as
+an ERB file and then loads the resulting YML as its configuration.
+
+## resque.yml
+
+This file is called `resque.yml` for historical reasons. We are **NOT**
+using Resque at the moment. It is used to specify Redis configuration
+values instead.

+As an example, we'll create a user named `gitlab` and add it to `JIRA-developers`
+group.

 ### Configuring GitLab
 
->**Note:**
-The currently supported JIRA versions are v6.x and v7.x. and GitLab
-7.8 or higher is required.
-
----
-
-Assuming you [have already configured JIRA](#configuring-jira), now it's time
-to configure GitLab.
-
-JIRA configuration in GitLab is done via a project's
-[**Services**](../project_services/project_services.md).
-
-To enable JIRA integration in a project, navigate to the project's
-**Settings > Services > JIRA**.
-
-Fill in the required details on the page, as described in the table below.
-
-| Setting | Description |
-| ------- | ----------- |
-| `Description` | A name for the issue tracker (to differentiate between instances, for example). |
-| `Project url` | The URL to the JIRA project which is being linked to this GitLab project. It is of the form: `https://<jira_host_url>/issues/?jql=project=<jira_project>`. |
-| `Issues url`  | The URL to the JIRA project issues overview for the project that is linked to this GitLab project. It is of the form: `https://<jira_host_url>/browse/:id`. Leave `:id` as-is, it gets replaced by GitLab at runtime. |
-| `New issue url` | This is the URL to create a new issue in JIRA for the project linked to this GitLab project, and it is of the form: `https://<jira_host_url>/secure/CreateIssue.jspa` |
-| `Api url`     | The base URL of the JIRA API. It may be omitted, in which case GitLab will automatically use API version `2` based on the `project url`. It is of the form: `https://<jira_host_url>/rest/api/2`. |
-| `Username` | The username of the user created in [configuring JIRA step](#configuring-jira). |
+>**Notes:**
+- The currently supported JIRA versions are `v6.x` and `v7.x.`. GitLab 7.8 or
+  higher is required.
+- GitLab 8.14 introduced a new way to integrate with JIRA which greatly simplified
+  the configuration options you have to enter. If you are using an older version,
+  [follow this documentation][jira-repo-docs].
+
+To enable JIRA integration in a project, navigate to your project's
+**Services ➔ JIRA** and fill in the required details on the page as described

You can find this number under the JIRA workflow administration (**Administration > Issues > Workflows**) by selecting **View** under **Operations** of the desired workflow of your project. The ID of each state can be found inside the parenthesis of each transition name under the **Transitions (id)** column ([see screenshot][trans]). By default, this ID is set to `2`. |

 After saving the configuration, your GitLab project will be able to interact
 with the linked JIRA project.

-- the project is named `GITLAB`
-- the user is named `gitlab`

+# Mattermost slash commands
+
+> Introduced in GitLab 8.14
+
+Mattermost 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 Mattermost.
+
+## Prerequisites
+
+Mattermost 3.4 and up is required.
+
+If you have the Omnibus GitLab package installed, Mattermost is already bundled
+in it. All you have to do is configure it. Read more in the
+[Omnibus GitLab Mattermost documentation][omnimmdocs].
+
+## Configuration
+
+The configuration consists of two parts. First you need to enable the slash
+commands in Mattermost and then enable the service in GitLab.
+
+
+### Step 1. Enable custom slash commands in Mattermost
+
+The first thing to do in Mattermost is to enable custom slash commands from
+the administrator console.
+
+1. Log in with an account that has admin privileges and navigate to the system
+   console.
+
+    ![Mattermost go to console](img/mattermost_goto_console.png)
+
+    ---
+
+1. Click **Custom integrations** and set **Enable Custom Slash Commands** to
+   true.
+
+    ![Mattermost console](img/mattermost_console_integrations.png)
+
+    ---
+
+1. Click **Save** at the bottom to save the changes.
+
+### Step 2. Open the Mattermost slash commands service in GitLab
+
+1. Open a new tab for GitLab and go to your project's settings
+   **Services ➔ Mattermost command**. A screen will appear with all the values you
+   need to copy in Mattermost as described in the next step. Leave the window open.
+
+    >**Note:**
+    GitLab will propose some values for the Mattermost settings. The only one
+    required to copy-paste as-is is the **Request URL**, all the others are just
+    suggestions.
+
+    ![Mattermost setup instructions](img/mattermost_config_help.png)
+
+    ---
+
+1. Proceed to the next step and create a slash command in Mattermost with the
+   above values.
+
+### Step 3. Create a new custom slash command in Mattermost
+
+Now that you have enabled the custom slash commands in Mattermost and opened
+the Mattermost slash commands service in GitLab, it's time to copy these values
+in a new slash command.
+
+1. Back to Mattermost, under your team page settings, you should see the
+   **Integrations** option.
+
+    ![Mattermost team integrations](img/mattermost_team_integrations.png)
+
+    ---
+
+1. Go to the **Slash Commands** integration and add a new one by clicking the
+   **Add Slash Command** button.
+
+    ![Mattermost add command](img/mattermost_add_slash_command.png)
+
+    ---
+
+1. Fill in the options for the custom command as described in
+   [step 2](#step-2-open-the-mattermost-slash-commands-service-in-gitlab).
+
+    >**Note:**
+    If you plan on connecting multiple projects, pick a slash command trigger
+    word that relates to your projects such as `/gitlab-project-name` or even
+    just `/project-name`. Only use `/gitlab` if you will only connect a single
+    project to your Mattermost team.
+
+    ![Mattermost add command configuration](img/mattermost_slash_command_configuration.png)
+
+1. After you setup all the values, copy the token (we will use it below) and
+   click **Done**.
+
+    ![Mattermost slash command token](img/mattermost_slash_command_token.png)
+
+### Step 4. Copy the Mattermost token into the Mattermost slash command service
+
+1. In GitLab, paste the Mattermost token you copied in the previous step and
+   check the **Active** checkbox.
+
+    ![Mattermost copy token to GitLab](img/mattermost_gitlab_token.png)
+
+1. Click **Save changes** for the changes to take effect.
+
+---
+
+You are now set to start using slash commands in Mattermost that talk to the
+GitLab project you configured.
+
+## Authorizing Mattermost to interact with GitLab
+
+The first time a user will interact with the newly created slash commands,
+Mattermost will trigger an authorization process.
+
+![Mattermost bot authorize](img/mattermost_bot_auth.png)
+
+This will connect your Mattermost user with your GitLab user. You can
+see all authorized chat accounts in your profile's page under **Chat**.
+
+When the authorization process is complete, you can start interacting with
+GitLab using the Mattermost commands.
+
+## Available slash commands
+
+The available slash commands so far are:
+
+| Command | Description | Example |
+| ------- | ----------- | ------- |
+| `/<trigger> issue create <title>\n<description>` | Create a new issue in the project that `<trigger>` is tied to. `<description>` is optional. | `/trigger issue create We need to change the homepage` |
+| `/<trigger> issue show <issue-number>` | Show the issue with ID `<issue-number>` from the project that `<trigger>` is tied to. | `/trigger issue show 42` |
+| `/<trigger> deploy <environment> to <environment>` | Start the CI job that deploys from one environment to another, for example `staging` to `production`. CI/CD must be [properly configured][ciyaml]. | `/trigger deploy staging to production` |
+
+To see a list of available commands that can interact with GitLab, type the
+trigger word followed by `help`:
+
+```
+/my-project help
+```
+
+![Mattermost bot available commands](img/mattermost_bot_available_commands.png)
+
+## Permissions
+
+The permissions to run the [available commands](#available-commands) derive from
+the [permissions you have on the project](../user/permissions.md#project).
