No more databases, comment moderation, or pesky updates to install, just your content. Markdown, Liquid, HTML & CSS go in. Static sites come out ready for deployment. Permalinks, categories, pages, posts, and custom layouts are all first-class citizens here. Sick of dealing with hosting companies? GitHub Pages are powered by Jekyll, so you can easily deploy your site using GitHub for free, custom domain name and all. Jekyll is a static site generator. It takes text written in your favorite markup language and uses layouts to create a static website. You can tweak the site’s look and feel, URLs, the data displayed on the page, and more.

Typically you’ll use jekyll serve while developing locally and jekyll build when you need to generate the site for production.
