# Add Chaotic-AUR repo + keyring to pacman, then install paru from there.
# Reference: https://aur.chaotic.cx/docs

# Steps from chaotic docs:
# 1. Get and sign the key
# 2. Install chaotic-keyring + chaotic-mirrorlist
# 3. Append repo to /etc/pacman.conf
#
# Body is wrapped in an os_family conditional: this script is a no-op on
# debian (or anything non-arch).
