 The cert-manager for Red Hat OpenShift (cert-manager) Operator must be pre-installed before creating an instance of {Project} ({ProjectShort}). For more information about cert-manager, see link:https://docs.openshift.com/container-platform/{NextSupportedOpenShiftVersion}/security/cert_manager_operator/index.html[cert-manager for Red Hat OpenShift overview].
 
-In previous versions of {ProjectShort}, the only available cert-manager channel was `tech-preview` which continues to work and is available until OpenShift v4.12. Installations of cert-manager on versions of {OpenShift} v4.14 and later must be installed from the `stable-v1` channel. For new installations of {ProjectShort} it is recommended to install cert-manager from the `stable-v1` channel.
