As a newbie I often felt repelled by FOSS project I want to contribute to, because even if code is clear and I might have found a piece of code to improve, a lot's of project don't even include the more minimalist instruction on "how to contribute" / "how does my build system/doc system work". If you are doing thing really standard, point to the standard doc of you build system. But most of the time first think you have to do is to spend days trying to guess how the fuck the project is organized. If your excuse is that you don't have time to write doc, maybe don't expect a lot of contributors, because guess what maybe they don't have time to guess what you didn't writeh.
