title: Basic Rails 404 Error Page
body: <p>I have been looking for a simple answer to this for a ridiculously long time and it seems like this has to be so plainly obvious and simple because no one has an easy, idiot proof tutorial.</p>
  
  <p>Anyway, all I want to do is to have a single 404.html static page that loads whenever ANY error is thrown.  Ideally this should only happen in production and staging.</p>
  
  <p>I feel like this should be the easiest thing to do...  but I can't figure it out.</p>
  
  <p>Any help is much appreciated.</p>
