+This library provides helper classes for simplified and more consistent navigation handling. This is mainly used by the IntelliJ plugin.
+
+The central class is `NavigationTarget`. This class encapsulates navigation and can easily be extended for other means than classic Architecture Components supported navigation such as dialogs. A `NavigationTarget` is usally passed via RX from the ViewModel to the Fragment.
+
+In the Fragment you can use `NavigationTarget.navigate()` to execute navigation.
+
+Additionally this library brings some extension functions for BottomNavigationViews, NavigationViews and Toolbars which all help you when implementing navigation.
+
+The plugin supports you in setting all those things up.
