+By default, all comments are stripped from the content. To preserve them, use the `preserve_comments` option, like this:
+
+```php
+$converter = new HtmlConverter(array('preserve_comments' => true));

+$html = '<span>Turnips!</span><!-- Monkeys! -->';
+$markdown = $converter->convert($html); // $markdown now contains "Turnips!<!-- Monkeys! -->"

 ### Style options
 
 By default bold tags are converted using the asterisk syntax, and italic tags are converted using the underlined syntax. Change these by using the `bold_style` and `italic_style` options.
