+# 1. Install Kepler using Helm from OCI registry
+helm install kepler oci://quay.io/sustainable_computing_io/charts/kepler \
+  --namespace kepler \
+  --create-namespace
+
+# Wait for Kepler pods to be running
+kubectl wait --for=condition=ready --timeout=120s pod -n kepler --all
+
+# 2. Verify installation
+kubectl get pods -n kepler
+
+# 3. Access metrics (port-forward)
+kubectl port-forward -n kepler svc/kepler 28282:28282
+
+# Test metrics endpoint
+curl http://localhost:28282/metrics | grep kepler_node_cpu_watts
+```
+
+> **📋 For Production Deployments:** Consider using the [Kepler Operator](https://github.com/sustainable-computing-io/kepler-operator#-getting-started) for advanced lifecycle management and operational capabilities.
