Sharing Plex with family, simple?

I've build up a smaller library on my "server" now. So far i've only used Plex locally to stream from my livingroom tv, but i wanna start sharing it with family and friends now. When i look into the settings on Plex, i looks like i can just set remote access to active, and the start inviting users. Is it really that simple? (I get that i need to setup permissions for users ofc, but is everything else that simple to do?)
