My notes with the steps to install Arch Linux with encrypted BTRFS (LUKS2) and GRUB.
If you stumbled upon this document looking for a guide to install Arch Linux, I recommend checking the official installation guide on the Arch Linux Wiki: https://wiki.archlinux.org/title/Installation_guide. This is not a guide, just some notes that I'm taking while trying this setup and getting fragments of information from the internet.
