Universal Star Rating provides shortcodes to give the author the opportunity to add ratings/reviews for desired data, products and services with the aid of a classic star rating system. You can make use of these shortcodes to embed a single inline star rating or a tabular list of star ratings.
To insert a single inline star rating inside a post just type <code>[usr 5]</code> where 5 is the rating/amount of stars.
To insert a tabular list of star ratings inside a post just type <code>[usrlist "Pizza:3" "Ice Cream:3.5" (...)]</code> where the first value is what you want to rate and the second value is the rating/amount of stars. Your list should consist of more than 1 key:value pairs.
