On npc spawn make a sound play?

Hi, i’m making a simple npc, using this


local NPC = { Name = "Namehere",
Class = "npc_manhack",
Model = "Modelhere",
Health = "1000",
KeyValues = { },
Category = category }


list.Set( "NPC", "npc_enemy", NPC )
	

I doubt thats right but also, what do i put in key values?
