 1. Run `npm run example:setup` to install dependencies and configure the local WP server.
 2. Run `npm run example:start` to start the WP server and Astro development server.
 
 > [!NOTE]
 > When you kill the long running process this will not shutdown the local WP instance, only Astro. You must run `npm run example:stop` to kill the local WP server.
