 ### DiscussionEmbed with SSO
 
-This is an example for setting up the DiscussionEmbed component with SSO.  This example config is also used on the Disqus React SSO example found here: https://disqus-sso-react-demo.glitch.me/.
+This is an example for setting up the DiscussionEmbed component with SSO.  Access to SSO is currently available as an add-on for users with a Business level subscription.  This example config is also used on the [Disqus React SSO example](https://disqus-sso-react-demo.glitch.me/), and more information about SSO can be found in [our SSO documentation](https://help.disqus.com/customer/en/articles/1717160-integrating-single-sign-on).
+
+Note: The `config.sso` object is not required for publishers integrating SSO only because `config.sso` is only used when the SSO login is present alongside the Disqus login.
