I think it would be nice if the page started with an architecture overview. First something that explains what it's for for someone for whom "multi-master replicated opaque key-value data store" isn't entirely sufficient. Then something to give an indication how multi-master replication is implemented. Also a few words to indicate if any authentication is needed (or planned), and if there's any searching planned.
I'd be happy to help draft this, if someone who knows the software can chat with me so I can learn the things I need. I'm afraid reading the Go source is currently beyond me.
