alt Hacker NewsStrongly agree with the sentiment, but I'd say if you're familiar with the terminal you may as well just install it and truly 'learn by doing'!
I could see this being great for true beginners, but for them it might be nice to have even some more basics to start (how do I open the terminal, what is a command, etc).
I feel that the tricky part now is you can “learn by doing” without ever knowing if you’re doing it right. You get something working, but your mental model can be completely off.
