Suggestions for learning how to implement Multiplayer

I found this link at the Unity site. I've also noticed a lot of frameworks are thrown around, what would you experienced Unity users recommend for a multiplayer fps? Should I go with the tutorials in the link provided? If any of you have any useful youtube tutorials, that's also greatly appreciated.

Thanks!

 

Quill has a series showing how to create one using Photon. It's positively ancient though having been made for Unity 4.

Brackeys has a newer series using UNET (Unity's Networking API), but despite being newer it's still very much out of date now having been made for Unity 5. Furthermore UNET is basically deprecated at this point and will soon be replaced by Unity.

Thanks Ryiah, Sounds like I should go with Quill's series.
