+## Important notice about the state of this project from the maintainers
+
+This project started at one time as a utility wrapper for keycloak.js as a simpler way to instantiate keycloak
+in the projects developed by [@dsb-norge](https://github.com/dsb-norge) , and our usage is tied to whatever 
+version of keycloak is supplied by RedHat SSO. This again means that later versions of keycloak will not be
+available for testing by the maintainers, and thus will not likely be supported or implemented by this project.
+
+Since this project has gained some traction out there in the OSS landscape, we feel like we are doing the community a disservice by
+letting the project go stale without communicating clearly what the initial goals were, and the current state of maintenance.
