Summary:
Adding documentation for the CLI for 2 reasons:
1. It's not immediately clear to most how the CLI is part of `react-native` and not the node module they installed. This begins clarifying.
2. I plan on adding some additional documentation to this section pending an upcoming PR I've discussed with Mike.
