Nothing manual required, you can federate with any other instance as long as you’re not on their ban list.
You basically use your instance’s search to search for a community on the remote instance, then your instance requests the top (5?) posts from the community on the remote instance. Once a user subscribes, all new posts going forward will be sent to your server via the federation.
At least I think that’s how it works, haha.
