One PR = One Commit

We prefer to review pull requests that contain a single commit as this makes it easier to keep the history clear for everyone and track what's changed.

If you are new to git, we'll squash your commits for you when merging your changes.

To squash your commits, use the interactive rebase method, git rebase -i HEAD~<commits>, squashing the commits into a single commit and changing your commit message to be the same as your pull request title.
