Using Arch Linux, there are many benifits. The fast speed, the amazing package manager, but one of the most cited reasons for using Arch is the AUR. The AUR is a repo that is maintained by the community, that anyone can add to. It has a lot of software that you can’t get using Pacman. However, there is no AUR helper on a default installation of Arch. The most popular is “yay”. I am going to explain how you can install, and use the yay AUR helper on a default installation of Arch Linux.
Oh ok. Isn’t that what pacman -Syyu does though?
Pacman does not update or install AUR packages. That’s probably the main difference between pacman and yay (or similar AUR helper)
