How to start a new bin

I was gifted my first worm bin. My brother was moving out of state and his worms were not. I was excited to try it, but had no idea how to keep my new roommates alive.
There are many amazing ways to get your worm bin started. These are merely some of the basics I've learned and will provide you a framework to help you start your own.
Container - I repurpose old rubbermaid totes, 50L in size, not too big, not too small and don't get too heavy down the road. Drill a bunch of holes in the bottom and lid to help provide some air movement and allow excess moisture to drain. I use a 3/16 inch drill bit.

Bedding - use a high carbon material. I typically use shredded newspaper, but there are many good ones and combinations of them can help bring more diversity. Peat moss, coco coir, shredded cardboard, newspaper, leaf mold, compost, etc. Moisture is key here. Worms breathe through their skin. Take a handful of your bedding and give it a squeeze. We're aiming for a drop or two to come out of our hand.
Adding Worms - Once you feel good about moisture, it is time to add the worms. You don't have to worry much about feeding them immediately (the worms can eat the bedding). Add the worms and let them get used to their new home. The first night or two, I'd put a light on them to keep them in the bin.
Feeding - start slowly. Add a small handful the first time and bury it into the bedding. Give it a few days and check back. If the food is gone or nearly gone you can add more, if not check again in a couple days. Don't be discouraged. It is perfectly normal for a new bin to start slowly as the microbial population begins to establish itself those first few weeks, those microbes help break down the food.
