In the Hierarchy of the Scene you can see three core Prefabs:
Core Scene Setup and Coherence Setup are present in all scenes and described in detail on Start Tutorial page.
Coherence Entity is the prefab that will change per Scene with different functionality. It has a standard CharacterControllerand Rigidbody as well as an Agent script which will handle movement functionality through the Input Manager in the Core Scene Setup prefab.
You can build this Scene via the Build Settings. Run the local Replication Server through the Window -> coherence -> Settings window and see how it works. You can try running multiple clients rather than just two and see replicating for each.
