This is great. We've got the app running in our simulator. Sure, it required a little bit of work to install the necessary tools, but the good news is that the only thing we'll need to do from this point forward is run the react-native init AppName command whenever we wish to create a new app. All our tools are installed and we're ready to start developing.

I want to call your attention to dependencies section. Here, you should only see two items listed: react and react-native. At the time of writing, React Native is at stable version 0.35.0.
