+# Issue closing pattern
+
+>**Note:**
+This is the administration documentation.
+There is a separate [user documentation] on issue closing pattern.
+
+When a commit or merge request resolves one or more issues, it is possible to
+automatically have these issues closed when the commit or merge request lands
+in the project's default branch.
+
+## Change the issue closing pattern
+
+In order to change the pattern you need to have access to the server that GitLab
+is installed on.
+
+The default pattern can be located in [gitlab.yml.example] under the
+"Automatic issue closing" section.
+
+> **Tip:**
+You are advised to use http://rubular.com to test the issue closing pattern.
+Because Rubular doesn't understand `%{issue_ref}`, you can replace this by
+`#\d+` when testing your patterns, which matches only local issue references like `#123`.
+
+**For Omnibus installations**
+
+1. Open `/etc/gitlab/gitlab.rb` with your editor.
+1. Change the value of `gitlab_rails['issue_closing_pattern']` to a regular
+   expression of your liking:
+
+    ```ruby
+    gitlab_rails['issue_closing_pattern'] = "((?:[Cc]los(?:e[sd]|ing)|[Ff]ix(?:e[sd]|ing)?) +(?:(?:issues? +)?%{issue_ref}(?:(?:, *| +and +)?))+)"
+    ```
+1. [Reconfigure] GitLab for the changes to take effect.
+
+**For installations from source**
+
+1. Open `gitlab.yml` with your editor.
+1. Change the value of `issue_closing_pattern`:
+
+    ```yaml
+    issue_closing_pattern: "((?:[Cc]los(?:e[sd]|ing)|[Ff]ix(?:e[sd]|ing)?) +(?:(?:issues? +)?%{issue_ref}(?:(?:, *| +and +)?))+)"
+    ```
+
+1. [Restart] GitLab for the changes to take effect.

-# Issue closing pattern
+This document was split into:
 
-When a commit or merge request resolves one or more issues, it is possible to automatically have these issues closed when the commit or merge request lands in the project's default branch.
-
-If a commit message or merge request description contains a sentence matching the regular expression below, all issues referenced from
-the matched text will be closed. This happens when the commit is pushed to a project's default branch, or when a commit or merge request is merged into there.
-
-When not specified, the default `issue_closing_pattern` as shown below will be used:
-
-```bash
-((?:[Cc]los(?:e[sd]?|ing)|[Ff]ix(?:e[sd]|ing)?|[Rr]esolv(?:e[sd]?|ing))(:?) +(?:(?:issues? +)?%{issue_ref}(?:(?:, *| +and +)?)|([A-Z][A-Z0-9_]+-\d+))+)
-```
-
-Here, `%{issue_ref}` is a complex regular expression defined inside GitLab, that matches a reference to a local issue (`#123`), cross-project issue (`group/project#123`) or a link to an issue (`https://gitlab.example.com/group/project/issues/123`).
-
-For example:
-
-```
-git commit -m "Awesome commit message (Fix #20, Fixes #21 and Closes group/otherproject#22). This commit is also related to #17 and fixes #18, #19 and https://gitlab.example.com/group/otherproject/issues/23."
-```
-
-will close `#18`, `#19`, `#20`, and `#21` in the project this commit is pushed to, as well as `#22` and `#23` in group/otherproject. `#17` won't be closed as it does not match the pattern. It also works with multiline commit messages.
-
-Tip: you can test this closing pattern at [http://rubular.com][1]. Use this site
-to test your own patterns.
-Because Rubular doesn't understand `%{issue_ref}`, you can replace this by `#\d+` in testing, which matches only local issue references like `#123`.
-
-## Change the pattern
-
-For Omnibus installs you can change the default pattern in `/etc/gitlab/gitlab.rb`:
-
-```
-issue_closing_pattern: '((?:[Cc]los(?:e[sd]|ing)|[Ff]ix(?:e[sd]|ing)?) +(?:(?:issues? +)?%{issue_ref}(?:(?:, *| +and +)?))+)'
-```
-
-For manual installs you can customize the pattern in [gitlab.yml][0] using the `issue_closing_pattern` key.

+# Automatic issue closing
+
+>**Note:**
+This is the user docs. In order to change the default issue closing pattern,
+follow the steps in the [administration docs].
+
+When a commit or merge request resolves one or more issues, it is possible to
+automatically have these issues closed when the commit or merge request lands
+in the project's default branch.
+
+If a commit message or merge request description contains a sentence matching
+a certain regular expression, all issues referenced from the matched text will
+be closed. This happens when the commit is pushed to a project's **default**
+branch, or when a commit or merge request is merged into it.
+
+## Default closing pattern value
+
+When not specified, the default issue closing pattern as shown below will be
+used:
+
+```bash
+((?:[Cc]los(?:e[sd]?|ing)|[Ff]ix(?:e[sd]|ing)?|[Rr]esolv(?:e[sd]?|ing))(:?) +(?:(?:issues? +)?%{issue_ref}(?:(?:, *| +and +)?)|([A-Z][A-Z0-9_]+-\d+))+)
+```
+
+Note that `%{issue_ref}` is a complex regular expression defined inside GitLab's
+source code that can match a reference to 1) a local issue (`#123`),
+2) a cross-project issue (`group/project#123`) or 3) a link to an issue
+(`https://gitlab.example.com/group/project/issues/123`).
+

+
+This translates to the following keywords:
+
+- Close, Closes, Closed, Closing, close, closes, closed, closing
+- Fix, Fixes, Fixed, Fixing, fix, fixes, fixed, fixing
+- Resolve, Resolves, Resolved, Resolving, resolve, resolves, resolved, resolving
+
+---
+
+For example the following commit message:
+
+```
+Awesome commit message
+
+Fix #20, Fixes #21 and Closes group/otherproject#22.
+This commit is also related to #17 and fixes #18, #19
+and https://gitlab.example.com/group/otherproject/issues/23.
+```
+
+will close `#18`, `#19`, `#20`, and `#21` in the project this commit is pushed
+to, as well as `#22` and `#23` in group/otherproject. `#17` won't be closed as
+it does not match the pattern. It works with multi-line commit messages as well
+as one-liners when used with `git commit -m`.
