You’ll find this post in your _posts directory. Go ahead and edit it and re-build the site to see your changes. You can rebuild the site in many different ways, but the most common way is to run jekyll serve, which launches a web server and auto-regenerates your site when a file is updated.

Adding New Posts

To add new posts, simply add a file in the _posts directory that follows the convention YYYY-MM-DD-name-of-post.ext and includes the necessary front matter. Take a look at the source for this post to get an idea about how it works.

Tags and Categories

If you list one or more categories or tags in the front matter of your post, they will be included with the post on the page as links. Clicking the link will bring you to an auto-generated archive page for the category or tag, created using the jekyll-archive gem.

Cover Images

To add a cover image to your post, set the “cover” property in the front matter with the relative URL of the image (i.e. cover: "/assets/cover_image.jpg").

Code Snippets

You can use highlight.js to add syntax highlight code snippets:

Use the Liquid {% highlight <language> %} tag to add syntax highlighting to code snippets.

For instance, this template…

{% highlight javascript %}    
function demo(string, times) {
for (var i = 0; i < times; i++) {
console.log(string);
}
}
demo("hello, world!", 10);
{% endhighlight %}

…will come out looking like this:

function demo(string, times) {
for (var i = 0; i < times; i++) {
console.log(string);
}
}
demo("hello, world!", 10);

Syntax highlighting is done using highlight.js. You can change the active theme in head.html.

Images

Lightbox has been enabled for images. To create the link that’ll launch the lightbox, add data-lightbox and data-title attributes to an <a> tag around your <img> tag. The result is:
