As someone very unfamiliar with a Unix, it's an interesting learning experience. But I would have prefer to know earlier the existence of the on-hover command documentation: perhaps add a button next to each commands that would show the same documentation; that would help people unfamiliar with Unix to know what they can do. Also perhaps a canonical/best practice answer for each question could be educational, perhaps with comments explaining why, again to help the newcomers: there's a bunch of valid answers, but I feel like there should be a better (or at least more elegant) solution.
