Notes on using Docker [Step by Step]
#Docker Installation:
First, add the GPG key for the official Docker repository to the system:
`curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -`
`sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"`
`sudo apt-get update`
Make sure you are about to install from the Docker repo instead of the default Ubuntu 16.04 repo:
