Code Mouseflow

Hi ,
i dont know where i have to put the code of mouse flow into the enfold theme.
This is the procedure:
After you create an account, you’ll receive a snippet of tracking code (JavaScript). If you already have an account, you can retrieve the code from the dashboard and under Websites > Edit.To install Mouseflow, simply copy/paste the entire snippet (for your account) to any page(s) you want to track before the closing body tag.

I’m not an expert and i’m learning about wordpress etc.
I have to

Please help me thank you
