+### Repository Quota Updates
+
+The repository quotas in the UI are updated after each backup.
+To update the quota during an operation the `update_used_quota` management command can be executed on a regular basis.
+
+There are example configs for systemd-timers in `contrib/communitybackup-quota-update.service` and `contrib/communitybackup-quota-update.timer`. Adjust the paths and the timers to your needs.

 ### BACKUP_MANAGE_PY
 
 `BACKUP_MANAGE_PY` is the command to run the `manage.py` file, including e.g. a Python interpreter, venv, etc. This must be a `pathlib.Path`
+
+### ADDITIONAL_FOOTER_NAV_ITEMS
+
+`ADDITIONAL_FOOTER_NAV_ITEMS` allows you to add additional links to the footer. This is a `list[str]`. Each item gets rendered as is into a `<li class=nav-item>`. So usually you want to continue the proper Bootstrap styling in the lst. E.g.:

+ADDITIONAL_FOOTER_NAV_ITEMS = ["""<a class="nav-link" href="https://example.com/>Example Link</a>""",]

+A list of the SSH public keys and their hashes to verify the server a User is connecting to.
+This is a list of tuples, containing the key and it's hash.
