I made a video showing how I use Jekyll to build our website for our lab - ProLabPrints.com. It came out a little long at 35 minutes, I was hoping for something a little more watchable around 15 minutes but that didn’t happen.
It isn’t meant to be a tutorial, just a way to show some of the ways we use liquid, includes, layouts and what not. I would have loved to see a few videos like this when I was learning Jekyll - even now I would still love to see how other people do things.
