Confusion with submitting changes

[Kyle Marek]

    I am looking at the pages on winehq for development for wine. I am
noticing that everything is talking about guidelines for making patches
and submitting patches. Can I not make a pull request on my changes? I
also noticed that it said that not everyone can submit patches and i
inferred by the linked pages that it's to prevent legal trouble. How can
I become eligible to submit changes?
