+## Environment Variables
+
+The following environment variables can be used to inject Caddy directives in the `Caddyfile` without modifying it:
+
+* `SERVER_NAME` change the server name
+* `CADDY_GLOBAL_OPTIONS`: inject [global options](https://caddyserver.com/docs/caddyfile/options)
+* `FRANKENPHP_CONFIG`: inject config under the `frankenphp` directive
+
 ## Enable the Debug Mode
 
 When using the Docker image, set the `CADDY_DEBUG` environment variable to `debug` to enable the debug mode:
 
 ```
 docker run -v $PWD:/app/public \
-    -e CADDY_DEBUG=debug \
+    -e CADDY_GLOBAL_OPTIONS=debug \
     -p 80:80 -p 443:443 \
