Then buy normal kingsford charcoal (do not buy auto light shit or use lighter fluid). Buy some fire starters (weber or whatever brand). And some like mesquite or pecan or whatever floats your boat.
Take top off grill, remove grilling surface, put charcoal in chimney, stuff fire starter in bottom (or newspaper in a pinch), light, set chimney on grill where charcoal goes, go masturbate for 15 minutes, when you come back coals should be white on the top and hot, dump the coals onto the charcoal grill area (wear grilling gloves it will be hot as fuck or an oven mitt works in a pinch), use a metal spade of some sort to push all the loose coals to the center. Then toss on a couple chunks of the wood and close the lid. Wait about 5-7 minutes and you are ready to grill. (obv if you want to grill something without smoky flavor skip the step with the wood)
ProTip: While grilling you want to open the grill as little as possible.
