 This project aims to support V8 replacement runtime for React Native. Designed as opt-in package, it is easy to integrate with existing React Native projects.
 
+## Installation for Expo projects (>= SDK 45)
+
+For managed projects, you can install through the single command:
+
+```sh
+$ expo install react-native-v8 expo-build-properties
+```
+
+- Please make sure you don't have [`"jsEngine": "hermes"`](https://docs.expo.dev/guides/using-hermes/#android-setup).
+
+For bare projects, you can run `expo prebuild -p android --clean` after the installation to prebuild again.
+
 ## Installation for React Native >= 0.66
 
 1. Install `react-native-v8` and a [v8-android variant](#v8-variants). For example, the `v8-android-jit`:

 ## iOS Support (Experimented)
 
 We did have experimented iOS support. To adopt V8 for Xcodeproj gets a little complicated, so we have a pre-shaped template.
