+## Automatic housekeeping
+
+GitLab automatically runs `git gc` and `git repack` on repositories
+after Git pushes. If needed you can change how often this happens, or
+to turn it off, go to **Admin area > Settings**
+(`/admin/application_settings`).
+
+## Manual housekeeping
 
 The housekeeping function runs `git gc` ([man page][man]) on the current
 project Git repository.
