Perhaps you meant to say “UNhelpful”?

Whenever I've contributed to outside projects, my motivation had been to avoid needing to maintain a fork. And whenever projects I'm a main on have had outside contributers, they very clearly had clear objectives they wanted the project to meet.

The much more important instructions for new developers is how to contribute guidance. Along with generally good documentation and design so they can actually make the changes they want to make.
