 If you wish, you can also run it headlessly on top of phantomjs and node:
 
-* Install [phantomjs 2](http://phantomjs.org/) (yes, it has to be 2 and above). Differs from platform to platform.
-* Install nightmare: `npm install nightmare`

+2. Install webdriverio: `npm install webdriverio@3.4.0` (4.x is broken)
+3. Copy `run-headless.config.json.SAMPLE` into `run-headless.config.json` (update if necessary), and edit your credentials into it.
+4. Hit the road:

+ ```sh
