Sync two machines/two instances of Millumin

I can see this question has been asked before, but I can't seem to find a clear answer.

I am trying to build a slave of my Millumin main setup on a back up computer.  Do I have to write an OSC command for each of the things I'm doing?  Or is there a way to just slave the two easily?  Any tutorials on how to set this up?

Thanks!
