This guide will use either a macOS or an ArchLinux base system, to prepare a microSD card with Arch Linux for Raspberry Pi.
If someone managed to do the initial setup using Windows, please let me know, so I can add to this guide.
This guide will be verbose at times for some simple tasks. This is intended to help people just starting out, so it's not confusing. If something confuses you, let me know and I'll try my best to answer it.
