+# GitLab JIRA integration
+
+GitLab can be configured to interact with JIRA
+
+*Note* Directions below are for JIRA v6.x and GitLab v6.x
+
+## Configuring JIRA
+
+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 -> User Management create a new user.
+For example, let's create user `gitlab`. We've also added `gitlab` user to group `jira-developers` which grants it access to projects.
+
+## Configuring GitLab
+
+In `gitlab.yml` enable [JIRA issue tracker section by uncommenting the lines](https://gitlab.com/subscribers/gitlab-ee/blob/6-8-stable-ee/config/gitlab.yml.example#L111-115).
+This will make sure that all issues within GitLab are pointing to the JIRA issue tracker.
+
+We can also enable JIRA service that will allow us to interact with JIRA issues. 
+
+For example, we can close issues in JIRA by a commit in GitLab.
+
+Go to project settings page and fill in the project name for the JIRA project, see [screenshot](jira_project_name.png).
+Next, go to the services page and find JIRA.
+
+1. Tick the active check box to enable the service.
+1. Supply the url to JIRA server, for example http://jira.sample
+1. Supply the username of a user we created under `Configuring JIRA` section, for example `gitlab`
+1. Supply the password of the user
+1. Optional: supply the JIRA api version, default is version 2
+1. Save
+
+Now we should be able to interact with JIRA issues, for example we can close a JIRA issue by commiting to our GitLab repository and referencing the JIRA issue( in the format of JIRAPROJECT-123). 
+
+For example, for project named NEW we commit with a commit message `Add new file fixes NEW-1` [screenshot](jira_service_commit.png) and that will close an issue NEW-1 in JIRA and add a comment with a link to the commit that closed the issue as shown on the [screenshot](jira_service_close_issue.png)
