 Available options:
 - `ADMIN_PASSWORD`: setup a specific admin password. If not set, a random password will be generated.
 - `ADMIN_IP`: set one or more ip allowed to access admin interface (separated by comma).
+- `LANG`: choose the language for jirafeau (default auto).
+- `AVAILABILITIES`: change the array for availablibilities that the user can select (see `docker-compose.yaml` for an example how to do that). Availability is the time the file should be available before it can be deleted.
 - `WEB_ROOT`: setup a specific domain to point at when generating links (e.g. 'jirafeau.mydomain.com/').
 - `VAR_ROOT`: setup a specific path where to place files. default: '/data'.
 - `FILE_HASH`: can be set to `md5`, `partial_md5` or `random` (default).
