 ## Config Override
 By default the provided `docker-compose.yml` file mounts `config.exs` in the Pleroma container, this file is a dynamic configuration that sources some values from the environment variables provided to the container (variables like `ADMIN_EMAIL` etc.).
 
 For those that want to change configuration that is not exposed through environment variables there is the option to mount the `config-override.exs` file which can than be modified to your satisfaction. Values set in this file will override anything set in `config.exs`. The override file provided in this repository disables new registrations on your instance, as an example.
