+GitLab has a great issue tracker but you can also use an external one such as
+Jira or Redmine. Issue trackers are configurable per GitLab project and allow
+you to do the following:
 
-- the 'Issues' link on the GitLab project pages takes you to the appropriate Jira issue index;
-- clicking 'New issue' on the project dashboard creates a new Jira issue;
-- To reference Jira issue PROJECT-1234 in comments, use syntax PROJECT-1234. Commit messages get turned into HTML links to the corresponding Jira issue.

+- the **Issues** link on the GitLab project pages takes you to the appropriate
+  issue index of the external tracker
+- clicking **New issue** on the project dashboard creates a new issue on the
+  external tracker
 
 ## Configuration
 
-### Project Service
+The configuration is done via a project's **Services**.
 
-You can enable an external issue tracker per project. As an example, we will configure `Redmine` for project named gitlab-ci.
-
-Fill in the required details on the page:
+### Project Service
 
-![redmine configuration](redmine_configuration.png)
+To enable an external issue tracker you must configure the appropriate **Service**.
+Visit the links below for details:
 
-* `description` A name for the issue tracker (to differentiate between instances, for example).
-* `project_url` The URL to the project in Redmine which is being linked to this GitLab project.
-* `issues_url` The URL to the issue in Redmine project that is linked to this GitLab project. Note that the `issues_url` requires `:id` in the url. This id is used by GitLab as a placeholder to replace the issue number.
-* `new_issue_url` This is the URL to create a new issue in Redmine for the project linked to this GitLab project.
+- [Redmine](../project_services/redmine.md)
+- [Jira](jira.md)
 
 ### Service Template
 
-It is necessary to configure the external issue tracker per project, because project specific details are needed for the integration with GitLab.
-The admin can add a service template that sets a default for each project. This makes it much easier to configure individual projects.
-
-In GitLab Admin section, navigate to `Service Templates` and choose the service template you want to create:
-
-![redmine service template](redmine_service_template.png)
-
-After the template is created, the template details will be pre-filled on the project service page.
-
-NOTE: For each project, you will still need to configure the issue tracking URLs by replacing `:issues_tracker_id` in the above screenshot
-with the ID used by your external issue tracker. Prior to GitLab v7.8, this ID was configured in the project settings, and GitLab would automatically
-update the URL configured in `gitlab.yml`. This behavior is now depecated, and all issue tracker URLs must be configured directly
-within the project's Services settings.
+To save you the hassle from configuring each project's service individually,
+GitLab provides the ability to set Service Templates which can then be
+overridden in each project's settings.
 
-Support to add your commits to the Jira ticket automatically is [available in GitLab EE](http://doc.gitlab.com/ee/integration/jira.html).
+Read more on [Services Templates](../project_services/services_templates.md).

-We need to create a user in JIRA which will have access to all projects that need to integrate with GitLab.
-Login to your JIRA instance as admin and under Administration go to User Management and create a new user.
-As an example, we'll create a user named `gitlab` and add it to `jira-developers` group.

+| `description`   | A name for the issue tracker (to differentiate between instances, for example) |
+| `project_url`   | The URL to the project in Redmine which is being linked to this GitLab project |
+| `issues_url`    | The URL to the issue in Redmine project that is linked to this GitLab project. Note that the `issues_url` requires `:id` in the URL. This ID is used by GitLab as a placeholder to replace the issue number. |
+| `new_issue_url` | This is the URL to create a new issue in Redmine for the project linked to this GitLab project |
+
+Once you have configured and enabled Redmine:
+
+- the **Issues** link on the GitLab project pages takes you to the appropriate
+  Redmine issue index
+- clicking **New issue** on the project dashboard creates a new Redmine issue
+
+As an example, below is a configuration for a project named gitlab-ci.

+# Services Templates
+
+A GitLab administrator can add a service template that sets a default for each
+project. This makes it much easier to configure individual projects.
+
+After the template is created, the template details will be pre-filled on a
+project's Service page.
+
+## Enable a Service template
+
+In GitLab's Admin area, navigate to **Service Templates** and choose the
+service template you wish to create.
+
+For example, in the image below you can see Redmine.
+
+![Redmine service template](img/services_templates_redmine_example.png)
+
+---
+
+**NOTE:** For each project, you will still need to configure the issue tracking
+URLs by replacing `:issues_tracker_id` in the above screenshot with the ID used
+by your external issue tracker. Prior to GitLab v7.8, this ID was configured in
+the project settings, and GitLab would automatically update the URL configured
+in `gitlab.yml`. This behavior is now deprecated and all issue tracker URLs
+must be configured directly within the project's **Services** settings.
