question about suiteport plugin

Hi,
We just purchased the suiteport plugin for SuiteCRM which you can read about here:
https://store.suitecrm.com/addons/wordpress-customer-portal-pro

Documentation is here:
https://www.appjetty.com/media/ExtensionDocument/Userguide/SuitePortSuiteCRMCustomerPortalforWordPress.pdf

My question is do I also have to have this installed?
