I'm a beginner at Docker but thought this could be useful to others looking to get started with Docker but are intimidated or unsure where to go. I distilled it down to the bare essentials. Being a beginner I'm sure I missed something so please post here or file a bug if something isn't clear or you see a better way of doing things. Cheers!

Also, I didn't do anything drastically different than the official example so feel free to check it out instead: https://github.com/enokd/docker-node-hello/
