+## 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 included as much information as possible in these slides
+
+- We recommend having a mentor to help you ...
+
+- ... Or be comfortable spending some time reading the Docker
+ [documentation](https://docs.docker.com/) ...
+
+- ... And looking for answers in the [Docker forums](forums.docker.com),
+  [StackOverflow](http://stackoverflow.com/questions/tagged/docker),
+  and other outlets
+
+---
+
+## Hands on, you shall practice
+
+- Nobody ever became a Jedi by spending their lives reading Wookiepedia
+
+- Likewise, it will take more than merely *reading* these slides
+  to make you an expert
+
+- These slides include *tons* of exercises
+
+- They assume that you have access to a cluster of Docker nodes
+
+- If you are attending a workshop or tutorial:
+  <br/>you will be given specific instructions to access your cluster
+
+- If you are doing this on your own:
+  <br/>you can use
+  [Play-With-Docker](http://www.play-with-docker.com/) and
+  read [these instructions](https://github.com/jpetazzo/orchestration-workshop#using-play-with-docker) for extra
+  details
