Create a README.md

[cgoecknerwald]

I would like to see a README.md, which is a Markdown file that goes in project file to explain what the project is, and how to use it.

• Make A README
• Markdown Cheatsheet
• Example README from my forked version of Justin's bootcamp repo.

BTW, Github does a pretty smart thing by automatically displaying READMEs on the home page of repositories. If you go to the home page of my forked bootcamp repository and scroll down, you can see the README without clicking on it.
