To properly light a charcoal BBQ grill or smoker, stack the charcoal in a very tight, high pile or use a charcoal starter tube. Don't make the pile too tight or you will cut down on the supply of air to the charcoal and thus slow the combustion or burning of the coals.
When stacked in a high pile the charcoal retains more heat and that heat is transferred to the other coals making them light much faster. Remember that heat rises and therefore the heat radiated from the lower coals will be captured and used to help the coals or briquettes above them to catch on fire. With enough space between the coals for the oxygen to flow, each charcoal briquette will help the ones above and beside it to ignite. 
After the coals are lit and glowing well, spread them as desired in the grill or smoker. Typically, you would spread the charcoals around the outside of the grill to give a uniform heat over the entire barbecue grill. However, sometimes you don't want the heat to be uniform and instead want to have a hot spot and a warm spot, like when grilling steaks or chops. In that case, stack the charcoal to one side of the grill and cook the steaks right over the charcoal. Make sure your GrillKicker™ is placed on the cool side of the grill so that the heat of the charcoal does not speed up the burning wood inside it.
