Show HN: Crash Course in IT

I keep being asked by the IT-adjacent folks at my job about stuff like "What is the cloud" and "Where should I start learning about IT?"

They usually come with the Google IT Fundamentals course or something like that, and while that stuff is good and all, it's a lot of time spent to learn some basic stuff that they don't really care about. They want to know an overview of stuff, so I'm trying to curate a list of videos, articles, games, activities, etc, that I can send to them and they can pick and choose what they're interested in.

If you have suggestions about what to add, please let me know! I've just got it hosted on a Github site because I don't want to pay for hosting on anything, and it's basic HTML for now.
