This guide is awesome. I couldn't help myself and I fixed a few
errors I found (and clarified a few parts). Hope you don't mind!

 <h3>What's the Deal With Jekyll?</h3>
 <p>Jekyll is a Ruby static site generator; it's code that takes input data like what layout you want to use, what page title to use, and the actual page content you're trying to publish, and it generates an HTML page.  In particular, Jekyll is useful for writing blog posts.  Once you establish the structure of your posts (i.e. the layout), you can concentrate on just writing the actual content of your post.  What you're left with is just static content that you can post on any webserver without having to worry about things like setting up a database to store your posts, because your posts are just files.</p>

Jekyll was create by <a href="http://tom.preston-werner.com">Tom Preston-Werner</a> of GitHub fame, and it is also used by GitHub for <a href="http://pages.github.com/">GitHub Pages</a>.  GitHub Pages can be used for both a blog and project pages on GitHub, and we'll be using it publish a blog to the web using git and GitHub.  This setup allows you to quickly and easily setup and publish a blog or website.</p>
