From my experience with Git, I've learned that GitHub's UI definitely makes the management of merge conflicts much easier. Most of my experience with git is through a cmd/terminal, so taking this course has definitely opened my eyes to the ease of use a GUI might provide. Additionally, I was able to get a nice refresher on markdown - something I need having no experience with using a "preview" option for markdown.
All in all, I think these are great tutorials, but I also wish there were parallel git bash tutorials. Maybe in the future!
