title: Add custom Javascript to Prestashop
body: <p>After asking on the Prestashop forum and receiving no reply I wanted to ask you guys and hope for an answer.</p>
  
  <p>I am trying to add an animated snow plugin to my shop but after looking at the header.tpl file which instructs you to not edit - how do I add my own Javascript to the head of my template?</p>
  
  <p>I duplicated the default-theme and I am working from that.</p>
