Zen Cart - Thwate certificate

I need a Word document with a step-by-step description how to install a Thwate security script to display in all my Zen Cart shop pages I have the script and it needs to be pasted into the body somewhere to display at the bottom of my footer (right in the same line as my banner) [login to view URL] I need the doc for future reference in case I change templates. Once I have followed your instructions and it works - I will release payment Thanks
