You log in to your home instance (kbin or Lemmy, doesn't matter which) and you can follow and participate in communities hosted on other servers, which can be kbin or Lemmy, doesn't matter which, because they support a common protocol (ActivityPub).

In fact, you can even interact with communities hosted on a Lemmy instance from a Mastodon instance, or Misskey. Heck, probably Pixelfed, though I haven't checked. Such is the beauty of the fediverse and protocols over platforms.
