+# Sample to deploy Elasticsearch and Kibana
+
+
+When a user installs the WebLogic operator Helm chart, the user can set
+`elkIntegrationEnabled` to `true` in their `values.yaml` to tell the operator to send the
+contents of the operator's logs to Elasticsearch.
+
+Typically, a user would have already configured Elasticsearch and Kibana in the
+Kubernetes cluster, and also would specify `elasticSearchHost` and `elasticSearchPort`
+in their `values.yaml` file to point to where Elasticsearch is already running.
+
+This sample configures the Elasticsearch and Kibana deployments and services.
+It's useful for trying out the operator in a Kubernetes cluster that doesn't already
+have them configured.
+
+It runs Elasticstack on the same host and port that the operator's Helm chart defaults
+to, therefore, the customer only needs to set elkIntegrationEnabled to true in their
+`values.yaml` file.
+
+To install ElasticSearch and Kibana, use:
+```
+  kubectl apply -f kubernetes/samples/scripts/elasticsearch_and_kibana.yaml
+```
+
+To remove them, use:
+```
+  kubectl apply -f kubernetes/samples/scripts/elasticsearch_and_kibana.yaml
+```
