pacman commands

[ncmprhnsbl]

some inaccuracies in the package manager section for pacman:
install from file: pacman -U [ package.tar.gz ]
while not completely incorrect, it should be:
pacman -U package.pkg.tar.zst ( or to a lesser extent: .pkg.tar.xz )

update package lists:
pacman -S
should be: pacman -Sy
