Introduction to Pelican

…and static site generators more generally. This is a summary of a presentation on Pelican I presented on May 9, 2016. It covers some of the building blocks of Pelican, and then provides several examples of Pelican in use. As a personal note, this presentation follows my own path of learning and growth with these technologies. I should note that I’m not a programmer or a web developer by trade; that everything I’ve done with Pelican has been as a part of another job or for personal projects. I hope to show you very practical applications of Pelican, rather than theoretical projects.
