This is my personal installation routine, which I continously expand and redefine. It aims for a simple (read minimal) Arch Linux installation, which is modern in the way that it uses UEFI and systemd-boot, secure in the way that it uses full-disk encryption using LUKS as well as flexibility by using LVM volumes for the root and home partition.

This installation process also aims for booting into the GUI as $user after the first reboot from the installation medium.

If you won't run into any issues, this should take you under an hour from nothing to a graphical interface. Good luck!
