testGame Worker Demo from 1.4 Plugin

Trying to figure out how this works. Still not clear where to assign the photon scripts and such to... The player prefab seems to have some script assigned - Photon View has an Observe field set to assign Player, but where is this pointing to?

Would be nice if there is a more hello-world based tutorial that outlines which components are needed for an object to be tracked for movement, or for presence etc.
