title: Configuration

These are all the configuration options you can set via environment variables.

Append any of the following keys to your `.env` file, and run `docker-compose up -d` to apply them.

:::info
The double-underscores are intentional, as all these settings are translated to yaml internally, a double-underscore indicates the next level.
:::
