-#### iOS
-
-1. In XCode, in the project navigator, right click `Libraries` ➜ `Add Files to [your project's name]`
-2. Go to `node_modules` ➜ `react-native-app-auth` and add `RNAppAuth.xcodeproj`
-3. In XCode, in the project navigator, select your project. Add `libRNAppAuth.a` to your project's
-   `Build Phases` ➜ `Link Binary With Libraries`
-4. Run your project (`Cmd+R`)<

-#### Android
-
-1. Open up `android/app/src/main/java/[...]/MainApplication.java`
-
-* Add `import com.rnappauth.RNAppAuthPackage;` to the imports at the top of the file
-* Add `new RNAppAuthPackage()` to the list returned by the `getPackages()` method
-
-2. Append the following lines to `android/settings.gradle`:
-   ```
-   include ':react-native-app-auth'
-   project(':react-native-app-auth').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-app-auth/android')
-   ```
-3. Insert the following lines inside the dependencies block in `android/app/build.gradle`:
-   ```
-     compile project(':react-native-app-auth')
