How i do a multiplayer game with Unity?

I have to do a multiplayer game with Unity, the question is how I do it, I would be grateful if you explain

  1. Learn how to use Unity.
  2. Learn how to make a game.
  3. Learn about networking.
  4. Learn about how to make a networking game in Unity.

But seriously, learn to use Google, so you come across things like M2H Unity Networking Tutorial | PDF | Lag | Computer Network.
