+
+Navigation views are presentation components that take a [`router`](routers.html) and a [`navigation`](navigation-prop.html) prop, and can display several screens, as specified by the `navigation.state`.
+
+Navigation views are controlled React components that can present the current navigation state. They manage switching of screens, animations and gestures. They also present persistent navigation views such as tab bars and headers.
