Initialize bootstrap modal in javascript

I am trying to use bootstrap front end library to automatically open a pop up page with instructions on how to use my site. I can make the modal show on page load but that’s all it shows. I want to show it over my regular page and then users can then dismiss it after they read the instructions. I don’t know how to make it happen. I am not using regular HTML pages on my site. I am using Omeka CMS. What I understand I need to do is the following but I don’t know how to actually do it. I need to:

  1. put the markup for the modal in a custom show.php file
  2. put the code to initialize the modal in script.js file (does it have to be script.js? I’m already using script.js for something else)

Right now I have all the code in show.php which shows the modal but not over my actual page and once you dismiss the dialog nothing happens. So somehow I need alter the show.php and create script.js file to make it work as intended. I don’t know what code to put in script.js and I don’t know how/where to call the script.js file.

This is the php that shows my modal but not in the way I want to use it

<!DOCTYPE html>
<html>
<head>
  <link rel="stylesheet" type="text/css" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap.min.css">
  <script src="http://code.jquery.com/jquery.js"></script>
  <script type="text/javascript"     src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/js/bootstrap.min.js"></script>


 <script type="text/javascript">
    $(window).load(function() {
      $('#myModal').modal('show');
    });
 </script>

</head>

<body>
  <!-- Modal -->

  <div id="myModal" class="modal fade">
  <div class="modal-dialog">
    <div class="modal-content">
       <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title">Modal title</h4>
      </div>
      <div class="modal-body">
        <p>One fine body&hellip;</p>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div><!-- /.modal-content -->
  </div><!-- /.modal-dialog -->
  </div><!-- /.modal -->
</body>
</html>

I would appreciate any help anyone can provide.

Thank you
