After compost pile is created and you have started adding carbon rich, wood chips, leaves and other nitrogen rich "green" materials (kitchen scraps, grass, clippings from the garden) in layers you should occasionally aerate the pile with shovel or fork so that it receives oxygen to help in the decomp. The bigger your compost pile the better. Heat is higher in a larger pile.
In the garden we add whatever we have into the pile.
