+ README.md
+ README.md

  Put a one-liner description at the top for TLDR types.
  Moved requirements section next so that it isn't lost in rest of the doc.
  Edited title headings tags +1 for each, ie <h3> -> <h2>
  Link to the setup.md page in the docs folder. I don't want to have to
  maintain copy in both that doc and the README.
