Jekyll is an open source static site generator useful as a blog publishing system.
Jekyll is great for people who aren't intimidated by editing HTML, CSS, and Markdown files, people who are on a shoestring budget, and people who want a blazing fast website. Jekyll may not be the best option for people who aren't interested in editing their websites in a text file and would rather have a WordPress-esque back-end from the beginning.
Jekyll is integrated into GitHub Pages, which made it an easy choice. Using Jekyll was also easier as there's not really a server or a database to configure and you can just get things started from day one. Running and verifying content changes locally for developers is super efficient as Jekyll runs locally, too.
