Photon / Multiplayer

Anyone know a good tutorial I can use for Photon? I wanna make my game multiplayer able with photon but can't find any good tutorial... so please let me know if u know anyone.

Photon Exitgames

I really have basic question:
As I understand the Photon server is hosted on Photon cloud and that server will manage connections and messages/packets between clients and all clients are interacting as alone unity application?
I use unity3d. SO there is no need to save unity standalone or webplayer game to webhost or game server, becaouse if first client run the game, the photon, on cloud, will know that and wait for others to join the first player/room. right?
