 ## API
@@ -45,17 +34,21 @@ hdr-histogram-percentiles-obj has two utility functions to use
 
 ### histAsObj(histogram, total)
 
-* `histogram`: A native-hdr-histogram object you want to get some values from in a js object
+* `histogram`: A hdr-histogram-js object you want to get some values from in a js object
 * `total`: the total amount recorded by the histogram, optional
 
 Returns a json object with the `min`, `max`, `average` (mean) and `stddev`
 
 ### addPercentiles(histogram, histAsObjResult)
 
-* `histogram`: A native-hdr-histogram object you want to retrieve the percentiles from
-* `histAsObjResult`: the result returned when `histAsObj` is called on some native-hdr-histogram object
+* `histogram`: A hdr-histogram-js object you want to retrieve the percentiles from
+* `histAsObjResult`: the result returned when `histAsObj` is called on some hdr-histogram-js object
+
+Returns the histAsObjResult with the percentiles properties added. Percentile properties are named `pNN_DD`, for the `NN.DD%` percentile. Eg., the 99th percentile is `p99`, while the 99.99th percentile is `p99_99`.
+
+### percentiles
 
-Returns the histAsObjResult with the percentiles properties added
+An array listing the percentiles that hdr-histogram-percentiles-obj adds, as numbers.
