This is probably the quickest and the easiest ways to get Docker and Docker Compose running on the Raspberry Pi. (Tested with Raspberry Pi B+ Rev 1.2)
After searching the Inter-Webs for hours and having several things not work for me, I decided something needed to be done about it.
curl -sSL https://get.docker.com | sh
Install Dockersudo usermod -aG docker pi
Add permission to Pi User to run Docker Commands
