+## Change storage path
+
+Pages are stored by default in `/home/git/gitlab/shared/pages`.
+If you wish to store them in another location you must set it up in
+`gitlab.yml` under the `pages` section:
+
+```yaml
+pages:
+  enabled: true
+  # The location where pages are stored (default: shared/pages).
+  path: /mnt/storage/pages

+Restart GitLab for the changes to take effect:
+
+```bash
+sudo service gitlab restart
+```
+
 ## Backup
 
 Pages are part of the regular backup so there is nothing to configure.
