-In particular, `app = Vizro()` exposes the Flask app through `app.dash.server`. As in the [above example with Gunicorn](#gunicorn), this provides the application instance to a [WSGI](https://werkzeug.palletsprojects.com/en/3.0.x/terms/#wsgi) server.
+Internally, `app = Vizro()` contains a Flask app in `app.dash.server`. However, as a convenience, the Vizro `app` itself implements the [WSGI application interface](https://werkzeug.palletsprojects.com/en/3.0.x/terms/#wsgi) as a shortcut to the underlying Flask app. This means that, as in the [above example with Gunicorn](#gunicorn), the Vizro `app` object can be directly supplied to the WSGI server.
 
 [`Vizro`][vizro.Vizro] accepts `**kwargs` that are passed through to `Dash`. This enables you to configure the underlying Dash app using the same [arguments that are available](https://dash.plotly.com/reference#dash.dash) in `Dash`. For example, in a deployment context, you might like to specify a custom `url_base_pathname` to serve your Vizro app at a specific URL rather than at your domain root.
