===============

There are a few @b[[manual steps]] you might want to do:

1. Optionally set up Genymotion if you don't want to use Android Virtual Device:

    @blue[[https://www.genymotion.com]]

2. Setup Android Development Environment + Simulator:

    @blue[[https://facebook.github.io/react-native/docs/getting-started.html]]

3. Add your SSH public key to Github if it isn't already in there.
