Thanks for making this guide! I teach beginners how to use the command-line and I completely agree with your approach of mentioning its relation to Finder at the very start. Most students treat the shell as an entirely separate system with no relation to the GUI they're used to. Since your guide seems Mac focused (I didn't know about the trick with dragging the folder to get the path), I was surprised to see you not mention `open`. I tell students if they completely forget where they are in the system, run `open .` to get back to a friendly Finder.

One advantage of using illustrations is that they are more or less timeless as symbolic representations of the GUI. Novices can get distracted by screenshots that have minor differences from the OS versions between the author's and the readers'.
