 - Fellow developers write and publish React Native modules to npm and open source them on GitHub.
 - Making modules helps grow the React Native ecosystem and community. We recommend writing modules for your use cases and sharing them on npm.
 - Read the guides on Native Modules ([iOS](http://facebook.github.io/react-native/docs/native-modules-ios.html), [Android](http://facebook.github.io/react-native/docs/native-modules-android.html)) and Native UI Components ([iOS](http://facebook.github.io/react-native/docs/native-components-ios.html), [Android](http://facebook.github.io/react-native/docs/native-components-android.html)) if you are interested in extending native functionality.
