First, you line each shelf with wet newspaper.
Next, you add some red worms (about 200 here) with wet paper strips for bedding.
Then, put some food scraps on top...
And put down another layer of moist bedding.
Finally, place the lid on top. Continue adding layers of food scraps and moist, shredded paper. Spray with water to keep scraps and paper wet.
Since we're here in Arizona, the trick is to prevent the worms from getting too hot and dried out. So, even though the instructions say to keep the bin outside in the summer, I keep it in my kitchen. The next upgrade will be to get a stand with wheels so that I can move the bin outside easily when it comes time to empty the compost.
I'll let you know how it goes!
