Can somebody share some co-sleeping basics?

I'm a first time mom of a 9 day old boy. While he starts off the night snuggled in a basket next to the bed he seems to be happiest when he gets to stay by my side skin-to-skin after the first night feeding. I was originally going to have a sidecar crib so that he can sleep safely, but now I love having him next to me at night. I would love to hear some co-sleeping basics and advice. I am a very light sleeper, and use a receiving blanket (not my down comforter) to cover him and my chest, and I'm beginning to feel more confident about not squishing him at night. What should I know before I embark on this journey?
