   `require('readable-stream').Readable` constructor, with `objectMode` forced
   to `true`.
 
-  If `options.decoder` is passed, each key/value pair will be transformed by it.
-  Otherwise, an object with `{ key, value }` will be emitted.
+  Set `options.keys` or `options.values` to `false` to only get values / keys. Otherwise receive `{ key, value }` objects.
 
   When the stream ends, the `iterator` will be closed and afterwards a
   `"close"` event emitted.
