-Async is a utility module which provides straight-forward, powerful functions for working with [asynchronous JavaScript](http://caolan.github.io/async/global.html).

+Async is a utility module which provides straight-forward, powerful functions for working with [asynchronous JavaScript](http://caolan.github.io/async/global.html). Although originally designed for use with [Node.js](https://nodejs.org/) and installable via `npm install async`, it can also be used directly in the browser.  A ESM version is included in the main `async` package that should automatically be used with compatible bundlers such as Webpack and Rollup.
 
-This version of the package is optimized for the Node.js environment. If you use Async with webpack, install [`async-es`](https://www.npmjs.com/package/async-es) instead.
+A pure ESM version of Async is available as [`async-es`](https://www.npmjs.com/package/async-es).
