+# Kubernetes OpenTelemetry Assets
+
+Kubernetes OpenTelemetry Assets must be used with OpenTelemetry data. With this package will be installed assets to monitor [Kubernetes clusters](https://kubernetes.io/).
+
+## Requirements
+
+You need Elasticsearch for storing and searching your data and Kibana for visualizing and managing it.
+You can use our hosted Elasticsearch Service on Elastic Cloud, which is recommended, or self-manage the Elastic Stack on your own hardware.
+
+## Setup
+
+TODO: Add how to install opentelemetry-collector
+
+For step-by-step instructions on how to set up an integration, see the
+[Getting started](https://www.elastic.co/guide/en/welcome-to-elastic/current/getting-started-observability.html) guide.
