Pet peeve of mine: READMEs starting to explain hoe efficient, performant or minimal something is without explaining wat it is and why it should exist in the first place. Or using overly vague terms that only make sense in a very narrow technical context. A ‘minimal isomorphic asynchronous worker framework’. Can mean a million things.
