 # NodeBB OAuth2 Multiple Client SSO
 
-This NodeBB plugin allows you to configure logins to multiple configurable OAuth2 endpoints, via the admin backend.
\ No newline at end of file
+This NodeBB plugin allows you to configure logins to multiple configurable OAuth2 endpoints, via the admin backend.
+
+## Caveat
+
+Different OAuth2 providers adhere to the standard differently.
+This plugin is tested primarily against the following providers:
+
+* [Auth0 by Okta](//auth0.com)
+* [Okta](//www.okta.com/)
+
+Support for other OAuth2 providers is _explicitly not guaranteed_.
+If you'd like to help this plugin play nice with other providers, please
+[open an issue](https://github.com/NodeBB/nodebb-plugin-sso-oauth2-multiple/issues).
