+In this page, we provide a way to monitor your OCM environment using OpenTelemetry Collector Addon and Prometheus-Operator.
 
+## Overview
+The OpenTelemetry Collector Addon is a pluggable addon for Open Cluster Management (OCM) that automates the deployment and management of OpenTelemetry collector on managed clusters. Built on the addon-framework, it provides observability and metrics collection capabilities across your multi-cluster environment.

-kubectl create -f manifests/setup
+# Clone the repository
+git clone https://github.com/open-cluster-management-io/addon-contrib.git
+cd addon-contrib/open-telemetry-addon
 
-# Wait until the "servicemonitors" CRD is created. The message "No resources found" means success in this context.
-until kubectl get servicemonitors --all-namespaces ; do date; sleep 1; echo ""; done
