first, download the game here
when you open the game for the first time, you'll have to download the Mineclonia pack.
once you're in Luanti, go to the "join game" tab, then type mc.cult9.xyz in the address bar.
if it's your first time playing, you'll have to register an account. then you can login.
that's it, have fun :)
