-| Env variable name | Description                                                                                                                                                                                                                                                                                                                                                    |
-|-------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
-| APP_URL           | Base URL (f.e. `https://your-domain.com` for a production setup or something like `http://localhost:8000` for a local HTTP-only setup)                                                                                                                                                                                                                         |
-| APP_FORCE_HTTPS   | If enabled, the application will threat all request as if they were HTTPS. This is useful if the app is behind a reverse proxy and the reverse proxy is HTTPS-only but the communication between reverse proxy and app is HTTP.                                                                                                                                |
-| TRUSTED_PROXIES   | Comma-seperated list of CIDR IP ranges that are considered trusted. The app will trust headers like the `X-Forwarded-For` requests from those IPs. The example above (`0.0.0.0/0,2000:0:0:0:0:0:0:0/3`) is a wildcard for all IP addresses. This is only safe, if it's not possible to bypass the reverse proxy and the reverse proxy is correctly configured. |
