-| `MUMBLE_SUPERUSER_PASSWORD` | Specifies the SuperUser (Admin) password for this server. If this is not given, a random password will be generated upon first startup.      |
-| `MUMBLE_VERBOSE`            | Set to `true` to enable verbose logging in the server                                                                                        |

+| `MUMBLE_CUSTOM_CONFIG_FILE`      | Specify a custom config file path - **all `MUMBLE_CONFIG_` variables are IGNORED** <br/>(it's best to use a path inside the volume `/data/`) |

+
+Note: In the unlikely case where a `<configName>` setting is unknown to the container, startup will fail with the following error. 
+
+
+```
+mumble-server  | [ERROR]: Unable to find config corresponding to variable "<configName>"
+mumble-server exited with code 1
+```
+
+The root cause of this error is the fact that this setting is incorrectly registered in the Mumble server code. You can workaround this error by 
+setting the `MUMBLE_ACCEPT_UNKNOWN_SETTINGS` environment variable to `true` and spelling `<configName>` exactly as written in the
+[Murmur.ini](https://wiki.mumble.info/wiki/Murmur.ini) documentation.
