So about 3 months after #dddeu, I introduced a decider in #dikdikdik, my score app for the #wiezen card game. Thank you again @thinkb4coding, for the inspiring talk!

For processes manager, the code is here, and I explain it in the talk.
You can integrate with a classic message passing infrastructure (message broker, or in memory queues if you don't need persistence) or by composition of aggregates ans processes.
