Once the recording is available, we should include the 101 video with @hamdiallam's demo in our docs as it covers a lot of useful info.

+100 to this. What would could help going from good to great would be to mark the video in relationship to different topic, so that folks can go fast/back to specific sections and would make it even more powerful / useable
