# app

The App Router works in a new directory named `app`. The `app` directory works alongside the `pages` directory to allow for incremental adoption. This allows you to opt some routes of your application into the new behavior while keeping other routes in the `pages` directory for the previous behavior. If your application uses the `pages` directory, please also see the [Pages Router](https://nextjs.org/docs/pages/building-your-application/routing) documentation.<br>
