uNet Spawning Objects

I have got everything working in my game, u can join match making, get in a game, run around and see other clients. Everything is working however i dont have a way to spawn the objects on the network.

I was hoping someone could help me in regards to spawning objects. I want the player to be able to 'pick up, 'drop and 'spawn objects / prefabs. Below is a link from unity wiki and an exert that explains what i need.

"With the server authoritative system of the Unity Network System, networked objects with NetworkIdentities must be “spawned” by the server using NetworkServer.Spawn(). This causes them to be assigned a NetworkInstanceId and be created on clients that are connected to the server"
