I'm a doctor so I'm little unaware of how to work with plugins
Hello Dr. Kanu, thank you for reaching out.
You'll need to install the Woocommerce plugin in order to install our plugin too.
Once installed, in your case we think that you could be installing an All Reviews Page in order to collect shop level (or service level) reviews, instead of product level reviews.
If you need further advise please contact our support at firstname.lastname@example.org
