 ## Requirements
 
-For latest version of Universal Sign In, `compileSdkVersion` must be {'>='} 35 and `kotlinVersion` must be {'>='} 2.0.21 in your Android project. If you use Expo SDK 53 or newer, these requirements are already met. Use [`expo-build-properties`](https://docs.expo.dev/versions/latest/sdk/build-properties/#example-appjson-with-config-plugin) to specify these values on Expo SDK {'<='} 52.

 The latest version of the Universal Sign In package supports (use older versions of the package if you run older React Native / Expo):
 
 |              | supported range |
 | ------------ | --------------- |
-| expo         | 52.0.40 - 57    |
-| react-native | 0.76.0 - 0.87   |

+| react-native | 0.81.0+         |
 
 > We recommend [Expo](https://expo.dev) and [EAS](https://expo.dev/eas) for building and deploying your React Native app. Expo offers the best developer experience and is well-supported by this library.
