 ```sh
-n98-magerun2.phar dev:theme:build-hyva --theme="Hyva/default"
+n98-magerun2.phar dev:theme:build-hyva [--production] <theme-name>
 ```
 
+Example: `n98-magerun2.phar dev:theme:build-hyva "Hyva/default"`
+
+The command starts in watch mode by default, as it is primarily designed for developers.
+
+If no theme is specified, an interactive mode allows you to select a theme from a list.
+
+If the `--production` flag is set, the command does not run in watch mode and will stop after the theme is built.
