-# ExNavigation
 
-A route-centric, batteries-included navigation library for Expo and
-React Native that works seamlessly on Android and iOS.
 
-## An important note about the future
+## This library is no longer maintained
+
+Please use ["react-navigation"](https://github.com/react-navigation/react-navigation), or [other alternatives](https://reactnavigation.org/docs/en/alternatives.html) instead.
 
-The successor to ExNavigation,
-["react-navigation"](https://github.com/react-community/react-navigation),
-has had semantically-versioned, stable releases since early 2018. A migration path from
-ExNavigation will be provided, but feel free to migrate before official guidance is available if
-you require some of the new functionality and performance in react-navigation.
 
-This means that ExNavigation is currently in maintenance mode -- we
-aren't actively adding new features unless we need them for our own
-projects, because further work is being directed towards
-react-navigation. Pull requests are still welcome.
