Step 1; Either build your own, or buy yourself a compost bin (refer to Off Campus Composting for examples)
Step 2; Collect your household food scraps from egg shells to banana peels, coffee grinds, shredded newspaper, yard trimmings (such as grass clippings, dead leaves, wood chips), etc. However, it may be a good idea to leave out meat, dairy and fish products as they can attract pests and take longer to breakdown
Step 3; Toss all of these scraps into your compost pit and mix it up
Step 4; After mixing, water it down a bit, but just to get it a bit moist! You don't want it too wet or it'll be a gross and muddy mess
Step 5; Remember to add fresh material to keep those bacteria happy! Also, mix it and water it at least once a week. A good way to check if your compost pile needs watering is to grab a handful of the material and feel if it is moist, if it is, your good!!
Step 6; After attending to your compost pile for a few months, your resulting product should be rich, dark soil that smells of fresh earth!
Step 7; Feed your garden and let your fruits and veggies know that you love them
