I would like to better understand:
1. My Client to relay relationships.
2. Relay to relay relationships.
3. Follower client to my relay relations.
4. Private vs public relay in this mix.
5. And caching/archiving my own content to not solely lean on others for storage.
Is there a plain English explanation of these concepts somewhere, so I can familiarize myself with how to set up my relays optimally?
