Basic Repo Documentation

This needs more information.

Many repositories have tons of "fluff" documentation in the readme, contributor files, and wikis. It makes them easy to contribute to.

We should think about doing the same.

Maybe:

• Developer guide
• Contributor guide (How to make a PR, get an issue)
• User guide
• Inline doc comments -> html documentation via documentation generator
