Ask HN: How do you document your personal projects?

I'm curious if/how people keep records on side projects they create. I do electrical and software engineering and I've found twitter's character limits make it useless because you can't go into much depth. I've also found setting up (and driving traffic to) a blog to be a very time consuming and inefficient process. Is there an easier way?

Hey you can document your process in markdown files files locally or you can create a github repo with that markdown file

That’s what I do and it has worked pretty well for me
