### Code Examples in Markdown

Syntax highlighting with GFM

    ```javascript
    function fancyAlert(arg) {
      if(arg) {
        $.facebox({div:'#foo'})
      }
    }
    ```

Or, indent your code 4 spaces

    Here is a Python code example
    without syntax highlighting:

        def foo:
          if not bar:
            return true

Inline code for comments

    I think you should use an
    `<addr>` element here instead.
