+
+Note that running on device requires [Apple Developer account](https://developer.apple.com/register/index.action) and provisioning your iPhone. This guide covers only React Native specific topic.
+
+## Accessing development server from device
+
+You can iterate quickly on device using development server. To do that, your laptop and your phone have to be on the same wifi network.
+
+1. Open `iOS/AppDelegate.m`
+2. Change the IP in the URL from `localhost` to your laptop's IP
+3. In Xcode select your phone as build target and press "Build and run"
+
+> Hint
+>
+> Shake the device to open developemt menu (reload, debug, etc.)
+
+## Using offline bundle
+
+You can also pack all the JavaScript code within the app itself. This way you can test it without development server running and submit the app to the AppStore.
+
+1. Open `iOS/AppDelegate.m`
+2. Follow the instructions for "OPTION 2":
+  * Uncomment `jsCodeLocation = [[NSBundle mainBundle] ...`
+  * Run given `curl` command in terminal from the root directory of your app
+
+Packager supports a couple of options:
+
+* `dev` (true by default) - sets the value of `__DEV__` variable. When `true` it turns on a bunch of useful development warnings. For production it is recommended to use `dev=false`.
+* `minify` (false by default) - whenever or not to pipe the JS code through UglifyJS.
+
+## Troubleshooting
+
+If `curl` command fails make sure the packager is running. Also try adding `--ipv4` flag to the end of it.
+
+If you started your project a while ago, `main.jsbundle` might not be included into Xcode project. To add it, right click on your project directory and click "Add Files to ..." - choose the `main.jsbundle` file that you generated.
