 Chrome options are nested in the `chromeOptions` object. A full list of options is at [the chromedriver site](https://sites.google.com/a/chromium.org/chromedriver/capabilities). For example, to show an FPS counter in the upper right, your configuration would look like this:

+PhantomJS
+-------------------------------------
+In order to test locally with [PhantomJS](http://phantomjs.org/), you'll need to either have it installed globally, or relative to your project. For global install see the [PhantomJS download page](http://phantomjs.org/download.html). For relative install run: `npm install --save-dev phantomjs`.
+
+Add phantomjs to the driver capabilities, and include a path to the binary if using local installation:
+```javascript
+capabilities: {
+  'browserName': 'phantomjs',
+
+  // should be able to omit this property if phantomjs installed globally
+  'phantomjs.binary.path':'./node_modules/phantomjs/bin/phantomjs'
+}
+```
+
+Jasmine tests should work without further customization. If you are using Mocha, or another framework, the driver will need to be adjusted accordingly:
+```javascript
+driver = new webdriver.Builder().
+	usingServer('http://localhost:4444/wd/hub').withCapabilities(webdriver.Capabilities.phantomjs()).build();
+```
