title: How to build a module in playframework 2
body: <p>It seems I can't find an instruction on <a href="http://www.playframework.org/">http://www.playframework.org/</a> about building a module for playframework 2.</p>
  
  <p>Anyone know if there are documentations for this or the steps require to build a module? </p>
  
  <p>Thanks.</p>
