uNet like photon

in photon i can do

 [PunRpc]
 public void RpcDoSomething(string example){
           print(example);
 }
 
 public void CallDoSomething(string example){
        photonview.RPC("RpcDoSomething", photontarget.others, example);
 }
 
 void Start()
 {
       CallDoSomthing("RpcDosomething will be called from all clients");
 }

but in uNet I'm not sure but, guess we need syncvar, Rpc, Command.....

am i right??

how do i do stuff like above in uNet??
