 ## API
 
-### iteratorStream(iterator[, options])
-
-  Create a readable stream from `iterator`. `options` are passed down to the
-  `require('readable-stream').Readable` constructor, with `objectMode` forced
-  to `true`.
+### `stream = iteratorStream(iterator[, options])`
 
-  Set `options.keys` or `options.values` to `false` to only get values / keys. Otherwise receive `{ key, value }` objects.
