+Strimzi Apache Kafka Operator
+=============================
+
+Strimzi provides a way to run an Apache Kafka cluster on Kubernetes
+in various deployment configurations by using kubernetes operators.
+Operators are a method of packaging, deploying, and managing a
+Kubernetes application.
+Strimzi Operators extend Kubernetes functionality, automating common
+and complex tasks related to a Kafka deployment. By implementing
+knowledge of Kafka operations in code, Kafka administration
+tasks are simplified and require less manual intervention.
+
+Installation steps
+------------------
+
+The recommended version of Strimzi for Kubernetes 1.19 is v0.28.0.
+The Strimzi cluster operator is deployed using helm to install the parent chart
+containing all of the required custom resource definitions. This should be done
+by a kubernetes administrator to allow for deployment of custom resources in to
+any kubernetes namespace within the cluster.
+
+Full installation instructions can be found in the
+`Strimzi Apache Kafka Operator helm Installation documentation`_.
+
+Installation can be as simple as:
+
+- Add the helm repo::
+
+    > helm repo add strimzi https://strimzi.io/charts/
+
+- Install the operator::
+
+    > helm install strimzi-kafka-operator strimzi/strimzi-kafka-operator --namespace strimzi-system --version 0.28.0 --set watchAnyNamespace=true --create-namespace
