A terminal needs every letter exactly right: the space between cd and the folder, the dot in notes.txt, the backslash in a path. Racing with the same commands, against the clock, makes them stick, so in the next lesson your fingers already know them. Fixing a bug's broken command trains your eye for the one wrong letter, and a round of memory makes sure you know what a command does before you run it.
Each game uses only commands from the lessons, level by level, so a beginner who has finished Level 1 races with dir and cd, Level 3 adds copy, move and rm, and Command Memory's last deck is Git's save points. New to the terminal? Start with the free lessons, or try any command on the practice terminal.
