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.

#### Syntax


    ``` [language] [title] [url] [link text]
    code snippet
    ```


#### Example (plain)

    ```
    $ sudo make me a sandwich
    ```

```
$ sudo make me a sandwich
```

#### Example With Syntax Highlighting a Caption and Link

    ``` ruby Discover if a number is prime http://www.noulakaz.net/weblog/2007/03/18/a-regular-expression-to-check-for-prime-numbers/ Source Article
    class Fixnum
      def prime?
        ('1' * self) !~ /^1?$|^(11+?)\1+$/
      end
    end
    ```

``` ruby Discover if a number is prime http://www.noulakaz.net/weblog/2007/03/18/a-regular-expression-to-check-for-prime-numbers/ Source Article
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](/docs/plugins/codeblock/) or [include_code](/docs/plugins/include-code/) liquid tags.
