+## Gitlab support
+To configure gitlab support you need to set gitopen.gitlab.domain:
+
+```
+git config --global gitopen.gitlab.domain  [yourdomain.here]
+```
+
+or
+
+```
+git config gitopen.gitlab.domain [yourdomain.here] in your local repository
+```
+
+By default it goes to the tree view but can be changed to go to the commits view like so:
+
+```
+git config gitopen.gitlab.urldifference commits
+```
+
