-## PREVIEW
+Most users will be best served starting at [`cryostat.io`](https://cryostat.io), the documentation website for Cryostat.
+Here you will find instructions on how to install Cryostat using the [Cryostat Operator](https://github.com/cryostatio/cryostat-operator),
+how to configure your applications to enable connectivity, and how to use the Cryostat application.
 
-This repository is in an active development, early preview state, and will eventually be used for `3.x` release
