I find that I just don't really know what I'm doing half the time, and find it difficult to find help at a genuinely practical level. It's either total beginner "This is called the terminal" or assumes you already know exactly what you're doing. Like the installation instructions for something I was looking at was literally "usual cmake build" with absolutely zero elaboration what that means. The other thing I don't like is when you look up how to do something and the answers are always "copy and paste this code" without explaining what any of it is or what it does.

Something else I'm still not at all sure about is where you're supposed to install things. Like at least on Windows I know you just bang everything in "Program files", but now there's bin, etc, home, usr, and whatever else and don't know where you're supposed to actually put things.
