title: deploying to heroku -- can't get rid of the "welcome to rails" default page
body: <p>I made a very simple rails app on local host and deleted public/index.html and changed the :root route to another page. It worked fine, but when I deployed to heroku, that index.html page shows up "Welcome Aboard, you're riding ruby on rails"</p>
  
  <p>How can I get rid of that in Heroku? Why is it there?</p>
