You definitely should learn - it's a lovely domain for geeking out -- but you first need to acquaint yourself with the technical domain. I honestly don't see how an example would get you from 0 to nodes up and running with understanding.
That first link has what you want: examples. But note how many pieces are involved and that it is not a 5 minute read :)
Top level, a project like this needs to communicate to the intended audiance -- here, people who are building F/T distributed actor systems -- what the project brings to the table, and imo they did a good job in that regard.
But maybe I should? Maybe that example would help? :)
