I tried to follow tutorials that use the command line. In hindsight that is terrible way to teach Git, which is fundamentally quite a visual thing.
It's like trying to teach people about filesystems only using cd, ls and pwd instead of just showing them a file tree.
Actually it's even worse because Git's CLI is so notoriously awful.
Eventually I tried Sourcetree which made it all make sense. Though Sourcetree isn't a very good GUI, mainly due to being hella slow. I eventually switched to GitX which is probably the best GUI I've used so far and makes everything extremely clear and easy. Unfortunately Mac only.
I now mostly use the Git Graph VSCode extension which is excellent and integrates pretty well with VSCode. Unfortunately it has been abandoned by its author and they frustratingly included a license clause saying only they could release versions of it, so it's basically abandonware. But it still works so I'll figure out a replacement when I have to.
