 The constructor accepts following arguments:
 
 * `fns` is an array of functions or stream instances.
-  * If a value is a function, a `Transform` stream is created, which calls this function with two parameters: `chunk` (an object), and an optional `encoding`. See [documentation](https://nodejs.org/api/stream.html#stream_transform_transform_chunk_encoding_callback) for more details on those parameters. The function will be called in context of the created stream.
