+
+React Native module for deploying script updates
+
+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 server with `gulp serve`, after installing the prerequisites described in the [project readme](https://github.com/Microsoft/hybrid-mobile-deploy/blob/master/README.md)
+* `cd` into `Examples/HybridMobileDeployCompanion` and run `npm install`
+* Open `index.ios.js` and add a deployment key (generate one using the UI at http://localhost:4000/)
+* Open `HybridMobileDeployCompanion.xcodeproj` in Xcode
+* Launch the project
