 ## Example Apps
 
-There are a lot of example apps at the [React Native Playground](https://rnplay.org/apps/picks). You can see the code running on a real device, which is a neat feature.
+There are some example apps in the [`Examples/` directory](https://github.com/facebook/react-native/tree/master/Examples) on GitHub. You can run the apps on a simulator or device, and you can see the source code for these apps, which is neat.
 
 The folks who built the app for Facebook's F8 conference in 2016 also [open-sourced the code](https://github.com/fbsamples/f8app) and wrote up a [detailed series of tutorials](http://makeitopen.com/tutorials/building-the-f8-app/planning/). This is useful if you want a more in-depth example that's more realistic than most sample apps out there.
 
 ## Development Tools
 
 [Nuclide](https://nuclide.io/) is the IDE that Facebook uses internally for React Native development. The killer feature of Nuclide is its debugging ability. It also has great inline Flow support.
 
+[Create React Native App](https://github.com/react-community/create-react-native-app) makes it significantly easier to get started with a React Native project. There's no need to use Xcode or Android Studio, and you can develop for your iOS device using Linux or Windows.
+
 [Ignite](https://github.com/infinitered/ignite) is a starter kit that uses Redux and a few different common UI libraries. It has a CLI to generate apps, components, and containers. If you like all of the individual tech choices, Ignite could be perfect for you.
 
 [CodePush](https://microsoft.github.io/code-push/) is a service from Microsoft that makes it easy to deploy live updates to your React Native app. If you don't like going through the app store process to deploy little tweaks, and you also don't like setting up your own backend, give CodePush a try.
