 This installation script aims for a simple (read minimal) Arch Linux installation, which is modern in the way that it uses UEFI, systemd-boot and Wayland, secure in the way that it uses full-disk encryption using LUKS as well as flexibility by using Btrfs subvolumes for the root and home partition.  
 
-Tested and working as of **July 2026**.
