I edited the title as afaik fix should only be used when it's in a part of the code base that influences the semver (as it bumps the patch component). Also @zeroshade do you merge via Github UI here?

Maybe would be nice to add some examples and/or guidelines on the contributing guide like on the angular contributing guidelines:
