Quickstart
Quickstart Guide Quickstart Guide
The Quickstart guide walks you through example code that introduces how to define actor systems, actors, and messages as well as how to use the test module and logging.
FSM
FSM example project FSM example project
This project contains a Dining Hakkers sample illustrating how to model a Finite State Machine (FSM) with actors.
Cluster
