For being decentralized, dolt is really not good at getting the message across, I don't find anything in the documentation how I can get the collaboration/repository stuff to work without DoltHub, which seems to be their centralized service.

One of the neat things with Git and others is that it doesn't really care about what type of endpoint you're fetching data from, you can `git clone` from a unix directory, NFS shared directory, over ssh, via Keybase and so on. Dolt doesn't seem to support anything else than using DoltHub (if it does, they really need to update the documentation).
