-### pify(input, [options])
+### pify(input, [promiseModule], [options])
 
-Returns a `Promise` wrapped version of the supplied function or module.
+Returns a promise wrapped version of the supplied function or module.
 
 #### input
 
-Type: `Function` `Object`
+Type: `function`, `object`
 
 Callback-style function or module whose methods you want to promisify.
 
+#### promiseModule
+
+Type: `function`
+
+Custom promise module to use instead of the native one.
+
+Check out [`pinkie-promise`](https://github.com/floatdrop/pinkie-promise) if you need a tiny promise polyfill.

 #### options
 
 ##### multiArgs
 
-Type: `boolean`<br>
+Type: `boolean`  
 Default: `false`
 
-By default, the promisified function will only return the second argument from the callback, which works fine for most APIs. This option can be useful for modules like `request` that return multiple arguments. Turning this on will make it return an array of all arguments from the callback, excluding the error argument, instead of just the second argument. This also applies to rejections, where it returns an array of all the callback arguments, including the error.
