Arch User Repository (AUR)
For packages not provided in the official repositories, the Arch User Repository (AUR) provides user-made PKGBUILD bash scripts which retrieve and build source code or binaries from non-Arch Linux sources. PKGBUILD scripts cannot be downloaded or run by pacman, but they contain all the necessary instructions and metadata to build packages which pacman can install. Unofficial AUR helper programs, like Yay or Paru, can automate installation from the AUR.
