I believe that on GitHub there are also visual examples.

For me, ultimately, Git is best understood when there are visuals. The command line is cool, but if there's a tool that begs for a UI it's Git.

Yeah, I know there are Git UI tools, so many the article should have suggested some of those as well?

I have yet to find a Git GUI that really feels right. Recommendations?

I've been using GitKraken which is paid (@ a fair $60 p/y). But I also see FOSS options mentioned on HN from time to time and intend to explore one of those. Perhaps I'll do an Ask HN later today?
