+  router: YourApp.Web.Router
 ```
 
 Config options:
 * `docs_path`: Specify the path where the documentation will be generated. If you want to serve the documentation directly from the `phoenix` you can specify `priv/static/docs`.
 * `theme`: HTML theme is generated using the [Aglio renderer](https://github.com/danielgtaylor/aglio).
