+# [Expo](https://expo.io/) Usage
+
+RNCamera of react-native-camera is heavyly based on Expo camera module. Thanks @aalices and Expo for the great work.
+
+So you don't need to use **react-native-camera** if you have the following config:
+
+- If you are using [Expo](https://expo.io)
+- If you are using [create-react-native-app](https://github.com/react-community/create-react-native-app)
+- If you eject a [create-react-native-app](https://github.com/react-community/create-react-native-app) app and are using [ExpoKit](https://docs.expo.io/versions/latest/expokit/expokit)
+
+## How to migrate from Expo to react-native-camera
+
+If you decide to eject without using ExpoKit, you can follow react-native-camera installation instructions and just change the usage of your Camera component to RNCamera:
+
+```diff
+- import { Camera } from 'expo';
++ import { RNCamera } from 'react-native-camera';
+
+- <Camera
++ <RNCamera
+```
+
+## How to migrate from react-native-camera to Expo Camera Module
+```diff
+- import { RNCamera } from 'react-native-camera';
++ import { Camera } from 'expo';
+
+- <RNCamera
++ <Camera
+```
