I actually want to try writing technical docs, but I can't seem to find a beginner friendly project/framework that I can pick up a small task and work on it. Do you have any suggestions? Shall I try approaching people in Mozilla etc where they always have some work or wait until I find a project that I personally use and lacks some docs so I can try working on it individually? I would rather have some kind of mentorship but I do not think people will invest time in a random person over the internet.
