-Browserify
+Browser
 ===========
-Use [Browserify](browserify.org) to build a version of library that can run client-side:
+The package has been build with a [Browserify](browserify.org) version (`npm run browserify`) and you can use the browser version by including in your code:
+
 ```
-$ browserify lib/png.js --standalone png > bundle.js
+import { PNG } from 'pngjs/browser';
 ```
-Then depending on your module system you can either `require('bundle.js')` or if you're not using module loader you can use plain old `<script src="bundle.js"></script>` tag and the library will be available under `window.PNG` or just `PNG`.
