XF 1.4 Installing a Live Chat Service Like Zopim


I have been trying to figure this our for a while. I want to install Zopim live chat service in my forum website, which requires me to paste the script code before the </body> tag in the html of the website.

I haven't figured out in which specific area I have to do this.

Could someone please assist?

The scrip would look something like:

<!--Start of Zopim Script-->
<script type="text/javascript">
Script would be here
<!--End of Zopim Script-->

Thanks guys.
