-React Native module for deploying script updates
+React Native module for deploying script updates using the Code Push service.
+
+Installation
+---
+
+```
+npm install --save react-native-code-push
+```
+
+After installing the React Native Code Push plugin, open your project in Xcode. Open `node_modules/react-native-code-push` in Finder, and drag the `CodePush.xcodeproj` into the Libraries folder of Xcode.
+
+In Xcode, click on your project, and select the "Build Phases" tab of your project configuration. Drag libCodePush.a from `Libraries/CodePush.xcodeproj/Products` into the "Link Binary With Libraries" secton of your project's "Build Phases" configuration.
+
+Finally, edit your project's `AppDelegate.m`. Find the following code:
+
+```
+jsCodeLocation = [NSURL URLWithString:@"http://localhost:8081/index.ios.bundle?platform=ios&dev=true"];
+```
+
+Replace it with the following:
+
+```
+jsCodeLocation = [CodePush getBundleUrl];
+```
+
+This change allows Code Push to load the updated app location after an update has been applied.
 
 Running the Example

-* Make sure you have https://github.com/Microsoft/hybrid-mobile-deploy cloned beside the react-native project in a folder called `website`. This is hacky, and will be cleaned up as soon as React Native's packager supports symlinks.
-* Start the CodePush server with `gulp serve`, after installing the prerequisites described in the [project readme](https://github.com/Microsoft/hybrid-mobile-deploy/blob/master/README.md)
+* Clone this repository
 * From the root of this project, run `npm install`
 * `cd` into `Examples/CodePushDemoApp`
 * From this demo app folder, run `npm install`
-* Open `Info.plist` and fill in the values for CodePushDeploymentKey and CodePushServerUrl
+* Open `Info.plist` and fill in the value for CodePushDeploymentKey
 * Run `npm start` to launch the packager
 * Open `CodePushDemoApp.xcodeproj` in Xcode
 * Launch the project
