 Running `grunt serve` enhances your workflow by allowing you to rapidly build Ionic apps without having to constantly re-run your platform simulator. Since we spin up a `connect` server with `watch` and `livereload` tasks, you can freely edit your CSS (or SCSS/SASS files if you chose to use Compass), HTML, and JavaScript files and changes will be quickly reflected in your browser.
 
 ### Building assets for Cordova
-Once you're ready to test your application in a simulator, `grunt build` will concatenate, obfuscate, and minify your JavaScript, HTML, and CSS files and copy over the resulting assets into your app's `www/` directory so they are ready to be served by Cordova.
+Once you're ready to test your application in a simulator or device, run `grunt cordova` to copy all of your `app/` assets into `www/` and build updated `platform/` files so they are ready to be emulated / run by Cordova.

+To compress and optimize your application, run `grunt build`. It will concatenate, obfuscate, and minify your JavaScript, HTML, and CSS files and copy over the resulting assets into the `www/` directory so the compressed version can be used with Cordova.
 
 ### Cordova commands
 To make our lives a bit simpler, the `cordova` library has been packaged as a part of this generator and delegated via Grunt tasks. To invoke Cordova, simply run the command you would normally have, but replace `cordova` with `grunt` and `spaces` with `:` (the way Grunt chains task arguments).
