Not technically a distribution per se but rather a better guided installer for Arch than its default one I think. I use it when I want to create a new, fresh ArchLinux install and it’s pretty damn effective! You can even run archdi from it to preinstall some packages you might find useful, such as a Window Manager (a WM such as Openbox) or a Desktop Environment (a DE, such as GNOME, KDE, or Cinnamon).
