I'm thinking of hosting my own instance on my synology. Are there any guides to do it? I see documentation on how to set up the docker but i'm not sure how to set up an url for it.

When an instance is down, I am wondering what to do in regards to accessing my communities. Sure I can make accounts on various instances and just sub to the same stuff on all of them for backups, but is there a less grindy way to manage that?
