add instructions to learning activity

[brettdimond]

The Learning activities page contains excellent context and background information for the proposed activity, which appears to take place during a live session of the workshop. However, if the intent is for this to also serve as a standalone Open Educational Resource, it would benefit from explicit instructions a participant could follow to perform the activity. As it stands, after reading the page and navigating to the Jekyll Images on Docker Hub, I'm not sure what to do next.

I'm a bit stuck on how to do this one properly- might even be best for me and the "guest speaker" who walked us through the activity (and my boss at my day job) to record a 5 minute video of the activity, as it can't really be written down in a traditional sense (we go line by line to explain the meaning of a basic Dockerfile). I'll touch base with Eka at our first Winter 1 WorkLearn meeting to see what she thinks, thanks for flagging!

After much reflection, and rolling out the prototype of my second workshop, I think the best way to meet the needs addressed here will be to record a short screencast (5-10 min) walking through a Dockerfile and the Docker Hub registry, bringing the viewer's attention to the most useful facets of available information there.

Of the activities we've trialed, this seems the most supportive of general learning, across platforms, for "what's going on" with Docker containerization :-) Going to focus on polishing the blockchain skills workshop enough to get it "live" first, but will address this before December!
