+Newsflash: [Vitaly Slobodin, the PhantomJS maintainer, is stepping down](https://groups.google.com/forum/#!topic/phantomjs/9aI5d-LDuNE),
+since [Google Chrome version 59 will ship with its own headless option](https://news.ycombinator.com/item?id=14101233).
+This means you're going to have to move all your capybara tests from PhantomJS into ChromeDriver.
+
+If you're coming from [poltergeist](https://github.com/teampoltergeist/poltergeist),
+which runs PhantomJS, you'lll have to install [selenium-webdriver](https://github.com/seleniumhq/selenium),
+
+{% highlight bash %}
+#!/bin/sh
+count=0
+while ./runtest; do
+  ((count++));
+  echo "Retry Count: $count"
+done
+{% endhighlight %}
+
+{% highlight bash %}
+{% endhighlight %}
+
+For more `chromeOptions`: check the [headless chrome documentation](https://developers.google.com/web/updates/2017/04/headless-chrome#cli).
+`disable-gpu` is temporarily required to run headless, but it may not be necessary in the future.
