React Native enables you to build world-class application experiences on native platforms using a consistent developer experience based on JavaScript and [React](http://facebook.github.io/react). The focus of React Native is on developer efficiency across all the platforms you care about - learn once, write anywhere. Facebook uses React Native in multiple production apps and will continue investing in React Native.
- Follow the [Getting Started guide](http://facebook.github.io/react-native/docs/getting-started.html) to install React Native and its dependencies.
- Check out this [tutorial](https://facebook.github.io/react-native/docs/tutorial.html) to walk through your first project that fetches real data and displays it in a list.
- [Open the UIExplorer example project](#examples) to see a list of components that ship with React Native.
- Install the [React Developer Tools](https://chrome.google.com/webstore/detail/react-developer-tools/fmkadmapgofadopljbjfkapdkoienihi) for Chrome or Firefox for better debugging [(read more)](http://facebook.github.io/react-native/docs/debugging.html).
- Try out apps from the [Showcase](https://facebook.github.io/react-native/showcase.html) to see what React Native is capable of!
[The website’s documentation](https://facebook.github.io/react-native/docs/) divided into multiple sections.
- There are **Guides** that discuss topics like [debugging](https://facebook.github.io/react-native/docs/debugging.html), [integrating with existing apps](https://facebook.github.io/react-native/docs/embedded-app-ios.html), and [the gesture responder system](https://facebook.github.io/react-native/docs/gesture-responder-system.html).
- The **Components** section covers React components such as [`View`](https://facebook.github.io/react-native/docs/view.html) and [`Navigator`](https://facebook.github.io/react-native/docs/navigator.html).
- The **APIs** section covers other libraries like [Animated](https://facebook.github.io/react-native/docs/animated.html) and [StyleSheet](https://facebook.github.io/react-native/docs/stylesheet.html) that aren’t React components themselves.
- Finally, React Native provides a small number of **Polyfills** that offer web-like APIs.
Another great way to learn more about the components and APIs included with React Native is to read their source. Look under the `Libraries` directory for components like `ScrollView` and `Navigator`, for example. The UIExplorer example is also here to demonstrate some of the ways to use these components. From the source you can get an accurate understanding of each component’s behavior and API.
The React Native documentation only discusses the components, APIs and topics specific to React Native (React on iOS and Android). For further documentation on the React API that is shared between React Native and React DOM, refer to the [React documentation](http://facebook.github.io/react/).
- 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.
If you encounter a bug with React Native we would like to hear about it. Search the [existing issues](https://github.com/facebook/react-native/issues) and try to make sure your problem doesn’t already exist before opening a new issue. It’s helpful if you include the version of React Native and OS you’re using. Please include a stack trace and reduced repro case when appropriate, too.
The GitHub issues are intended for bug reports and feature requests. For help and questions with using React Native please make use of the resources listed in the [Getting Help](#getting-help) section. There are limited resources available for handling issues and by keeping the list of open issues lean we can respond in a timely manner.
