An instance is just a way to access Lemmy. Lemmy.world, lemm.ee, sh.itjust.works, feddit.uk, etc - you can use any of these to access Lemmy and interact with, and see, all the same content.
It’s a problem because most communities are hosted on lemmy.world at the moment, but if lemmy.world ever dies they’ll die with it.
It does come preinstalled with them, that’s the whole point of Jackett. You just need to enable them in the dashboard.
