 . Log in into the Openshift console as `kubeadmin` user (or any cluster administrator).
-. Navigate to `Operators` -> `OperatorHub`.
-. Search for `AMQ Streams` - click on the 'AMQ Streams' operator.

 Install it with the default values and wait for the message telling you it has been installed and is ready for use.
