Me and my mom are making a compost pile how do i start and what are all the things i can put in it?

The simplest would be to take 10 feet of chicken wire, form it into a circle and wire it together, then stake it to the ground. A step up would be to put 4 posts in the ground, a 3' x 3' square. Staple or wire chicken wire to 3 or 4 sides of it. 3 sides makes it easier to turn the compost. The more sun it gets, the faster it will compost. You can add leaves, gr clippings, plant clippings that are not diseased, preferably not weeds, coffee grounds and the filter, tea bags, egg shells, nut shells, sawdust, all vegetable matter from your kitchen, cooked or raw. Try not to add leftover veges that have er or sauce on them, unless you rinse them off. Do not put in any meat, eggs, cheese or other dairy products. You can add cow and chicken manure. It helps heat it up. Avoid horse manure, it is too full of seed. I add all my old potting soil. Try to break everything down into small pieces, especially the egg shells to help them compost faster. Try to use a ratio of 2 parts dry waste to 1 part wet waste when you start your pile so it doesn't turn into mush. Keep the pile moist but not wet and turn it twice a week during the summer. If you turn it too often it doesn't get a chance to heat up inside. And last but not least, you can dissolve a packet or block of yeast in water and pour it over the pile in the beginning to help get the microbes going. Worms are helpful too. Good Luck!
