Cosmick Aggregate Rating Help

I’ve added the rating form, the review page but I’m stuck on Showing the Aggregate Rating. The directions say:
Aggregate Rating
Place <?php csr_get_overall_rating(); ?> in your templates for getting aggregate rating.

I don’t know php nor do I know where to “Place” this in my template or how.

Can anyone help.

Here’s the two pages I’d like to add it to:

https://www.vegan-bites.com/ above the feedback form

https://www.vegan-bites.com/reviews/ at the top of my review page.

Thank you.
