title: understand how opsworks and custom cookbooks work together
body: <p>I have my stack on opsworks and app is deploying fine (cake php).</p>
  
  <p>Now I have to configure some things like chmod, php versions, etc etc... I'm reading about this but don't know exactly whats the best way to do this.</p>
  
  <p>Question 1 - Should I do this with custom deploy JSON or via custom cookbooks?</p>
  
  <p>Question 2 - Whats the correctly way to work with custom cookbooks? Fork original AWS repositories, update recipes and then use it in my stack?</p>
