Yeah, I was aware of why you may have left things out, which is why I originally wasn't going to add more, but since you are aiming at beginners, I worry that they might not consider the consequence of just adding sudo to all of their commands.
But then it occurred to me, hey, this place is great for discussion, so I'd add it anyway as a sort of discussion point.
Also, the markdown on your edit is a bit off.
hahaha yeah I noticed that about the markdown when I was reading it over. But yes pleas feel free to bring up something that might not be clear as I go through this. We both know how deep this can be.
