Hey all, per our dev meeting I took a stab at establishing what documentation each project should have. This is a bit opinionated so I'd appreciate if everybody could look it over and make sure they're on board with it or amend it to be something they think is more useful.

My hope is that once we agree on a final form of this, everybody can finish documenting the stuff they're working on so that others can more easily join their projects.
