-# Strimzi: Kafka as a Service
+# Strimzi: Apache Kafka on Kubernetes
 
 Strimzi provides a way to run an [Apache Kafka®](https://kafka.apache.org) cluster on 
 [Kubernetes](https://kubernetes.io/) or [OpenShift](https://www.openshift.com/) in various deployment configurations.
 See our [website](https://strimzi.io) for more details about the project.
 
+## CRD Upgrades
+
+**!!! IMPORTANT !!!** 
+Strimzi 0.23 and newer supports only the API version `v1beta2` of all Strimzi custom resources. 
+This is a required as part of the migration to `apiextensionsk8s.io/v1` which is needed because Kubernetes 1.22 will remove support for `apiextensions.k8s.io/v1beta1`. 
+Migration to `v1beta2` needs to be completed for all Strimzi CRDs and CRs before the upgrade to 0.23 or newer.
+For more details about the CRD upgrades, see the [documentation](https://strimzi.io/docs/operators/0.22.1/deploying.html#assembly-upgrade-resources-str).

 ### Upgrading your Clusters
 
+To upgrade the Strimzi operator, you can use the `helm upgrade` command.
+The `helm upgrade` command does not upgrade the [Custom Resource Definitions](https://helm.sh/docs/chart_best_practices/custom_resource_definitions/).
+Install the new CRDs manually after upgrading the Cluster Operator.
+You can access the CRDs from our [GitHub release page](https://github.com/strimzi/strimzi-kafka-operator/releases) or find them in the `crd` subdirectory inside the Helm Chart.
+
 The Strimzi Operator understands how to run and upgrade between a set of Kafka versions.
 When specifying a new version in your config, check to make sure you aren't using any features that may have been removed.
 See [the upgrade guide](https://strimzi.io/docs/latest/#assembly-upgrading-kafka-versions-str) for more information.
