+## Overview
+
+This is a reimplementation of [duplexer](https://www.npmjs.com/package/duplexer) using the
+Streams3 API which is standard in Node as of v4. Everything largely
+works the same.
+
+## Install
+
+```sh
+npm install duplexer3
+```
+
+## API
+
+### duplexer3
+
+Creates a new `DuplexWrapper` object, which is the actual class that implements
+most of the fun stuff. All that fun stuff is hidden. DON'T LOOK.
+
+```js
+duplexer3([options], writable, readable)
+```
+
+```js
+const duplex = duplexer3(new stream.Writable(), new stream.Readable());
+```
+
+Arguments
+
+* __options__ - an object specifying the regular `stream.Duplex` options, as
+	well as the properties described below.
+* __writable__ - a writable stream
+* __readable__ - a readable stream
+
+Options
+
+* __bubbleErrors__ - a boolean value that specifies whether to bubble errors
+	from the underlying readable/writable streams. Default is `true`.
