 In order to integrate CodePush into your Android project, please perform the following steps:
 
+### Plugin Installation for Expo (Android)
+
+React Native Code Push comes packaged with a plugin to automate some of the setup process:
+
+1. Open your Expo app config file (app.config.json or app.config.js instead of app.json).
+
+2. Insert the following into the plugins section of your config (Don't duplicate configuration, if the 'react-native-code-push' item already exists, simply add the android portion.). Create the plugins section if it doesn't already exist. CodePushPublicKey is optional, see Code Signing setup for more information.
+
+    ```javascript
+    "plugins": [
+      [
+        'react-native-code-push',
+        {
+          android: {
+            CodePushDeploymentKey: 'YOUR_ANDROID_CODE_PUSH_KEY',
+            CodePushPublicKey: 'YOUR_ANDROID_PUBLIC_KEY',
+          }
+        }
+      ]
+    ]
+    ```
+
+3. Replace `YOUR_ANDROID_CODE_PUSH_KEY` with the Deployment key.
+
+4. Run `npx expo prebuild` to regenerate your native code with the codepush dependencies.

 ### Plugin Installation and Configuration for React Native 0.60 version and above (Android)
 
 1. In your `android/settings.gradle` file, make the following additions at the end of the file:
 
     ```gradle
     ...
     include ':app', ':react-native-code-push'
-    project(':react-native-code-push').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-code-push/android/app')
+    project(':react-native-code-push').projectDir = new File(["node", "--print", "require.resolve('react-native-code-push/package.json')"].execute(null, rootDir).text.trim(), "../android/app")
     ```
 
 2. In your `android/app/build.gradle` file, add the `codepush.gradle` file as an additional build task definition to the end of the file:
 
     ```gradle
     ...
-    apply from: "../../node_modules/react-native-code-push/android/codepush.gradle"
+    apply from: new File(reactNativeRoot, "react.gradle")
+    apply from: new File(["node", "--print", "require.resolve('react-native-code-push/package.json')"].execute(null, rootDir).text.trim()).getParentFile().getAbsolutePath() + "/android/codepush.gradle"
     ...
     ```

 ## iOS Setup
 
 Once you've acquired the CodePush plugin, you need to integrate it into the Xcode project of your React Native app and configure it correctly. To do this, take the following steps:
+
+### Plugin Installation for Expo (iOS)
+
+React Native Code Push comes packaged with a plugin to automate some of the setup process:
+
+1. Open your Expo app config file (app.config.json or app.config.js instead of app.json).

+
+    ```javascript
+    "plugins": [
+      [
+        'react-native-code-push',
+        {
+          ios: {

+          },
+        }
