-## Polyfills #
 Angular is built on the latest standards of the web platform.
 Targeting such a wide range of browsers is challenging because they do not support all features of modern browsers.
 
-You can compensate by loading polyfill scripts ("polyfills") on the host web page (`index.html`)
-that implement missing features in JavaScript.

 The suggested polyfills are the ones that run full Angular applications.
 You may need additional polyfills to support features not covered by this list.
 Note that polyfills cannot magically transform an old, slow browser into a modern, fast one.

+## Enabling polyfills
 
+[Angular CLI](https://github.com/angular/angular-cli/wiki) users enable polyfills through the `src/polyfills.ts` file that
+the CLI created with your project.
 
-### Mandatory polyfills ##
+This file incorporates the mandatory and many of the optional polyfills as JavaScript `import` statements.
+
+The npm packages for the _mandatory_ polyfills (such as `zone.js`) were installed automatically for you when you created your project and 
+their corresponding `import` statements are ready to go.
+You probably won't touch these.
+
+But if you need an optional polyfill, you'll have to install its npm package with `npm` or `yarn`.
+For example, [if you need the web animations polyfill](http://caniuse.com/#feat=web-animation),
+you could install it with either of the following commands:
+
+<code-example language="sh" class="code-shell">
+  npm install --save web-animations-js
+  yarn add web-animations-js
+</code-example>
+
+Then open the `polyfills.ts` file and un-comment the corresponding `import` statement
+as in the following example:
+
+<code-example title="src/polyfills.ts">
+  /**
+  * Required to support Web Animations `@angular/platform-browser/animations`.
+  * Needed for: All but Chrome, Firefox and Opera. http://caniuse.com/#feat=web-animation
+  **/
+  import 'web-animations-js';  // Run `npm install --save web-animations-js`.
+</code-example>
+
+If you can't find the polyfill you want in `polyfills.ts`, 
+add it yourself, following the same pattern:
+
+1. install the npm package
+1. `import` the file in `polyfills.ts`
