# Turn-by-turn navigation

Turn-by-turn navigation, also referred to as active guidance, is likely what comes to mind when you think about a typical navigation experience: a user receives turn-by-turn instructions as they progress along the route.

You can use the complete drop-in navigation UI, [`NavigationViewController`](https://docs.mapbox.com/ios/navigation/api/3.28.2/navigation/documentation/mapboxnavigationuikit/navigationviewcontroller/), to add a pre-configured turn-by-turn navigation experience to your application or you can build a custom UI using the UI components individually.

These guides will help you understand the UI provided by `NavigationViewController` and the data that powers it.
