-Jira, Redmine, YouTrack, or Bugzilla. Issue trackers are configurable per GitLab project
-and allow you to do the following:
+GitLab has a great [issue tracker](../user/project/issues/index.md) but you can also use an external one
+such as Jira, Redmine, YouTrack, or Bugzilla. External issue trackers are configurable per GitLab project.
 
-- you can reference these external issues inside GitLab interface
-  (merge requests, commits, comments) and they will be automatically converted
-  into links
+Once configured, you can reference external issues using the format CODE-123, where CODE is a unique code
+for the tracker, and 123 is the issue number in the tracker. These references in GitLab 
+merge requests, commits, or comments are automatically converted to links to the issues.
 
-You can have enabled both external and internal GitLab issue trackers in parallel. The **Issues** link always opens the internal issue tracker and in case the internal issue tracker is disabled the link is not visible in the menu.
+You can keep GitLab's issue tracker enabled in parallel or disable it. When enabled, the **Issues** link in the
