 ### Install Karpenter Helm Chart
 
 Use Helm to deploy Karpenter to the cluster.
 
 Before the chart can be installed the repo needs to be added to Helm, run the following commands to add the repo.

 #### Deploy a temporary Prometheus and Grafana stack (optional)
 
 The following commands will deploy a Prometheus and Grafana stack that is suitable for this guide but does not include persistent storage or other configurations that would be necessary for monitoring a production deployment of Karpenter. This deployment includes two Karpenter dashboards that are automatically onboaraded to Grafana. They provide a variety of visualization examples on Karpenter metrices.
 
-```bash
-helm repo add grafana-charts https://grafana.github.io/helm-charts
-helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
-helm repo update

-kubectl create namespace monitoring

 The new stack has only one user, `admin`, and the password is stored in a secret. The following command will retrieve the password.
