In the general sense, what one does in a WSM or BGE or whatever is you decide how many chunks you want, and you place them through your charcoal in the ring. Then you light it up Minion style, and the charcoal, as it's heating, preheats the chunks, and when it comes up to temp it's burning sweet blue all the way.
Once you get used to how many chunks you like, typical advice is "a few fist sized chunks" but obviously your tastes may vary, you'll never have to add in more chunks through the cook, but if you do! Simply preheat.
