# API documentation

- [Documentation for the master branch](https://github.com/expo/expo/blob/master/docs/pages/versions/unversioned/sdk/constants.md)

# Installation in managed Expo projects

For managed [managed](https://docs.expo.io/versions/latest/introduction/managed-vs-bare/) Expo projects, please follow the installation instructions in the [API documentation for the latest stable release](#api-documentation). If you follow the link and there is no documentation available then this library is not yet usable within managed projects — it is likely to be included in an upcoming Expo SDK release.

# Installation in bare React Native projects

For bare React Native projects, you must ensure that you have [installed and configured the `react-native-unimodules` package](https://github.com/unimodules/react-native-unimodules) before continuing.
