PR Reviewer Guidelines

• It's best to pull the branch locally and test it, rather than just looking at the code online!
• Check that all code is adequately covered by tests - if it isn't feel free to suggest the addition of tests.
• Always make comments, even if it's minor, or if you don't understand why something was done.
