## What *is* Docker?
- "Installing Docker" really means "Installing the Docker Engine and CLI".
- The Docker Engine is a daemon (a service running in the background).
- This daemon manages containers, the same way that an hypervisor manages VMs.
- We interact with the Docker Engine by using the Docker CLI.
- The Docker CLI and the Docker Engine communicate through an API.
- There are many other programs, and many client libraries, to use that API.

## Why don't we run Docker locally?
- We are going to download container images and distribution packages.
