Linux Desktop on Apple Silicon in Practice

NOTE: Time flies, and it's been almost five years(!) since I wrote this. Beaware the text below is now outdated (e.g., now Asahi Linux has graphics acceleration even better than this). The commands listed are up-to-date.

mkdir && cd

mkdir my_dir
cd my_dir
