SoulseekQT LINUX

So i just downloaded the new soulseekqt from the right side bar
i opened it an extracted the file to my desktop from there i double clicked and it opened fine
i was wondering does that mean its installed? or am i missing a step? i dont remember it being this easy to install something lol i havent used linux in forever.
thanks in advance!

It's a fixed binary, just like the Windows version as well: the executable includes everything!
in the forum there's a pinned how to if U prefer a start button
