-### pProps(map, [mapper], [options])
+### pProps(map, mapper?, options?)
 
 Returns a `Promise` that is fulfilled when all promises in `map` and ones returned from `mapper` are fulfilled, or rejects if any of the promises reject. The fulfilled value is the same as `map`, but with a fulfilled version of each entry value, or the fulfilled value returned from `mapper`, if defined.
