Agree. I am in the process of launching a new Open-Source project for Civil/Mechanical/Chemical engineers. In my gut feelings, this software shall be used by at least 10x Engineers compared to the number who may actually help code it. So, there must be a way for those Users to contribute back to the project. Even if it is simply improving the docs. If I use a static site generator such as Hugo to generate the docs (EDIT: user manual in our language), there must be a way for users (not developers) to submit correction/updates to the docs. I can't expect them to create a GitHub issue either, so I have to think about a way to do this. i.e. In this case, non-code contributions are far more important than the actual pull request.
