A brief introduction
This was initially written to support in-person, instructor-led workshops and tutorials
You can also follow along on your own, at your own pace
We recommend having a mentor to help you ...
... Or be comfortable spending some time reading the Docker documentation ...
... And looking for answers in the Docker forums, StackOverflow, and other outlets
Nobody ever became a Jedi by spending their lives reading Wookieepedia
