It was suggested by the sign up process at the top of which domain I should join. I don’t remember how, it’s already a blur, but afterwards I saw people saying the registration process needed to add a way of directing users to smaller instances as a thing to lighten the load and stop everyone going to lemmy.world and it confused me because that’s literally what happened to me.
Anyway I also noticed it had a steam deck community and that was good enough for me.
