Added some missing instructions to setting up the DB locally.
Added some very general guidelines for contributing to this project. TLDR: Very permissive, basically don't change the existing styles (don't change the design to "Cyan Moon" or "Magenta Moon" if the other pages are already "Red Moon") , and requires tests to be made for features which are core to payments and User Auth.
Basically the idea is that if it's going to lead to a customer losing their money because the site gets hacked, we don't want that, so there should be some basic testing ahead of time.
