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.

To add1 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.

Jekyll also offers powerful support for code snippets:

1 def print_hi(name)
2   puts "Hi, #{name}"
3 end
4 print_hi('Tom')
5 #=> prints 'Hi, Tom' to STDOUT.
