+### Running the demo app
+You may also play with CodePush by using its demo app. Here are the steps you need to perform in order to observe an app update:
+- register with the service (`nativescript-code-push register`) and add the demo app to your account (`nativescript-code-push app add <appname> <platform> nativescript`)
+- once the app is registered you will see its deployment keys in the console, use them to update the ones in the [demo](https://github.com/EddyVerbruggen/nativescript-code-push/blob/master/demo/demoapp/main-view-model.ts)
+- go to src and run `npm run preparedemo` - this will build the plugin and add a reference to the demo app
+- prepare an app that will be used as an "update version" (for example, uncomment one of the CODEPUSH labels and comment the APPSTORE label), then run `tns build <platform>`
+- release the update (`nativescript-code-push release <appname> <platform>`)
+- you can ensure it appears in the list with updates (`nativescript-code-push deployment history <appname> Staging`)
+- prepare an app that will be used as an "official release version" (for example, comment the CODEPUSH label and uncomment the APPSTORE label), then run `tns run <platform>`
+- when the app is deployed on the device, you should see the "official release version" along with information about an installed update
+- close the app (and remove it from device's recent apps to ensure its next start will be a cold start) and run it again - you should now see the "update version" of the app
