Trouble teaching Git? New tool to try!

I discovered this interactive, online Git training tool: https://www.katacoda.com/courses/git and thought it might be of interest. The advantage (IMHO) is that students do not have to have anything other than a browser with an internet connection on their machine at all: no need for a CLI (or for everyone to be using the same CLI), etc. — you can even run this on a tablet or phone! (This isn’t the best of the katacoda courses I’ve tried — it still assumes more CLI knowledge than I’d like), but if you want students to be able to experiment and have everyone using the same setup, this might be an option.
