Please note that this only works for PHP >= 5.3 and WP-Comment Rating >= 1.3.
Please also note that comments_template() will only work if the shortcode is placed in a page or a post. It will not work in a sidebar for example.
You have to copy & paste the source-code into a file maybe called 'my-shortcode-ranking-filter-comment-template.php' and upload it to your /wp-contents/plugins/ folder. Then activate it right from the "Plugin" menu in your WordPress installation.
After that you can access the shortcode by using this in the editor (example):
[my_shortcode_ranking do="best-rated" limit="7"]
You can use the same attributes as described in the FAQ (question 6): http://wp-buddy.com/documentation/plugins/wordpress-comment-rating-plugin/faq/
