+#### Custom Caddyfile Configuration
+
+When using FrankenPHP, you may specify a custom Caddyfile using the `--caddyfile` option when starting Octane:
+
+```shell
+php artisan octane:start --server=frankenphp --caddyfile=/path/to/your/Caddyfile
+```
+
+This allows you to customize FrankenPHP's configuration beyond the default settings, such as adding custom middleware, configuring advanced routing, or setting up custom directives. You may consult the [official Caddy documentation](https://caddyserver.com/docs/caddyfile) for more information on Caddyfile syntax and configuration options.
