  <!-- font awesome css -->
  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css/font-awesome.min.css">
  <link href='https://fonts.googleapis.com/css?family=Lobster' rel='stylesheet' type='text/css'>
  <!-- this app's own css -->
  <link rel="stylesheet" type="text/css" href="/css/main.css"/>


<!-- Next import js files -->
  <!-- jquery -->
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
  <!-- then bootstrap -->
  <script type="text/javascript" src="//maxcdn.bootstrapcdn.com/bootstrap/3.3.4/js/bootstrap.min.js"></script>

  <script src="https://www.gstatic.com/firebasejs/5.5.0/firebase.js"></script>

  <script type="text/javascript">
  
    //replace this with the config in the code snippet provided from Firebase.
    var config = {
      apiKey: '<%= process.env.API_KEY %>', // this references the API_KEY environemnt variable!
      authDomain: "databaseexample-5d86a.firebaseapp.com",
