Reading only gets you so far. I learn best from hands on experience. I never read the toy instructions as a kid. Sorry.
Why does it say optional if it's needed?
Because whether a homeserver requires an invite code is independent.
Our homeserver does require invites because it provides hosting services at scale, and we have to manage resources.
It is like how some relays are paid.
Pubky Ring is just a keychain, it doesnt care which pubky app or homeserver you use.
