what the repositories are for - what gets put in world vs extra or even galaxy
I have checked the wiki and also searched this forum and read the FAQ but cannot figure out what the different repositorys are and when to choose one over another. For example
❯ sudo pacman -Ss pulseaudio-alsa
world/pulseaudio-alsa 2-5
ALSA Configuration for PulseAudio
extra/pulseaudio-alsa 2-5
ALSA Configuration for PulseAudio
do I pick the world or extra? I am also confused as to what galaxy is for. I understand to eliminate systemd artix needs its own repositories, I just don't understand the meanings of each, and when given an option which one to pick. If someone could guide me as to what these mean or where I can find more information on the subject that would be appreciated.
