Having trouble setting this up

Hey - I found out abut jasmine-given from a frontend masters tutorial. I'm trying to do the setup now for a different project, but using jasmine 2.4 instead of 1.3. Here's my SpecRunner.html

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>Jasmine Spec Runner v2.4.1</title>

  <link rel="shortcut icon" type="image/png" href="lib/jasmine-2.4.1/jasmine_favicon.png">
  <link rel="stylesheet" href="lib/jasmine-2.4.1/jasmine.css">

  <script src="lib/jasmine-2.4.1/jasmine.js"></script>
  <script src="lib/jasmine-2.4.1/jasmine-html.js"></script>
  <script src="lib/jasmine-2.4.1/boot.js"></script>

  <script type="text/javascript" src="spec/helpers/jasmine-given.js"></script>

   <!-- include vendor files here... -->
   <script type="text/javascript" src="vendor/coffee-script.js"></script>
   <script type="text/javascript" src="number-shortening-filter.js"></script>
   <script type="text/coffeescript" src="spec/number-shortening-filter-spec.coffee"></script>

</head>

<body>

  <script type="text/javascript">

</body>
</html>

My test file is spec/number-shortening-filter-spec.coffee. Just to try and get it to do something, I made it

describe "Testing describe", ->
  Given -> @subject = Array 1,2,3
  Then -> @subject == null

When I serve the SpecRunner.html though, I get the jasmine test-runner page that says "No specs found".

Here's what my filestructure looks like: selection_001

searls / jasmine-given
