title: getting a capybara session for a remote browser
body: <p>I cannot find anything that shows the right way to pass in capabilities and create a remote session. something like the below</p>
  
  <pre><code>Capybara.default_driver = :Selenium
  @session = Capybara::Session.new :selenium
  </code></pre>
  
  <p>Could anyone point me in the right direction on how to do this? I have seen numerous examples of how to register a remote like this <a href="https://blog.testingbot.com/2012/02/19/selenium-cucumber-capybara" rel="nofollow">https://blog.testingbot.com/2012/02/19/selenium-cucumber-capybara</a>, but nothing to get the instance of it so that I can act on it in the code.</p>
