Throw stuff in bin.
Keep throwing stuff in bin.
Dump used cooking water on top here and there, rinse compost bucket (aka sludge bucket) out and dump water on top here and there.
Allow strange and fantastic things to sprout out of the top. See how many strange and fantastic things show up. (That's a tomato plant sprouting out of the pile in the picture.)
Next spring sift the whole pile through 1/2-inch hardware cloth sifter, throw chunks back in bin, spread sifted compost on garden.
Tah-da. Composting made easy.
