+Running with WebDriver
+----------------------
+
+`run()` method detects when PhantomJS gets ready. It's handy to use with WebDriver (Selenium).

+```javascript
+var phantomjs = require('phantomjs-prebuilt')
+var webdriverio = require('webdriverio')
+var wdOpts = { desiredCapabilities: { browserName: 'phantomjs' } }
