+### Requirements
+
+This is a `node` based build app so having node installed is an obvious requirement!
+
+`react-native` requires you to have the proper emulators installed for your targeted operating system. Check out the [React Native docs at Facebook](https://facebook.github.io/react-native/docs/getting-started.html) to get the install instructions. Make sure to use the instructions under the "Building Projects with Native Code" tab.

+(Optional) `npm` is installed with node but I recommend `yarn` package management. Instruction to install Yarn [can be found here](https://yarnpkg.com/en/docs/install).
