How do I install discord and other applications?

I’m new to Linux and heard many great things about it so I installed it. I tried installing discord but I cant seem to open it. Help?

Hi and welcome.
You may wish to look at the wiki in general, including the introductions.
But the section you are looking for specifically is here:

TLDR: Use your graphical package manager - probably “Pamac” or labeled “Add/Remove Software”


This should be most relevant.
