+## Details
+
+The `ratingType` string currently has two possible options, "likes"
+and "fiveStar". When the "likes" scheme is used, the result of
+`getRating` and the `vote` parameter of `postRating` are boolean
+values. When "fiveStar" is used, the value is an integer representing
+the number of stars out of five.
+
