With the backtick_codeblock filter you can use Github’s lovely back tick syntax highlighting blocks. Simply start a line with three back ticks followed by a space and the language you’re using. Tab in four spaces for your code snippets, and then finish your code block with three more back ticks.

Note: Back tick code blocks are only supported in HTML and Markdown. With the Textile markup language, use the codeblocks instead.

Syntax

``` language
    code snippet
```

Example

``` ruby
    class Fixnum
      def prime?
        ('1' * self) !~ /^1?$|^(11+?)\1+$/
      end
    end
```

class Fixnum
  def prime?
    ('1' * self) !~ /^1?$|^(11+?)\1+$/
  end
end

This is a nice, lightweight way to add a highlighted code snippet. For features like titles and links you’ll want to look at the codeblock or include_code liquid tags.
