+## Passing Options
+
+Options can be passed explicitly as command-line arguments to the service or they can be provided by environment variables prefixed with `SERVICE_`. For example, to run the service on port 8000:
+
+```bash
+# Example passing command-line args
+$ go run main.go --port=8000

+# Example passing by environment variables
+$ SERVICE_PORT=8000 go run main.go

+-   Print the OpenAPI spec
+-   Print JSON Schemas
+-   Run database migrations
+-   Run customer scenario tests
+-   Bundle common actions into a single utility command, like adding a new user

+### Custom Commands with Options
 
 If you want to access your custom options struct with custom commands, use the [`huma.WithOptions(func(cmd *cobra.Command, args []string, options *YourOptions)) func(cmd *cobra.Command, args []string)`](https://pkg.go.dev/github.com/danielgtaylor/huma/v2#WithOptions) utitity function. It ensures the options are parsed and available before running your command.
