-You need to modify some settings. To do this, inspect the chart to retrieve these values ​​in a file:
+To install the Prometheus Operator Helm chart in your OVHcloud Managed Kubernetes cluster, you need to customize some values.
+To do this, you can set parameters on the command line (`--set param.name=value`) or create a local file based on the values from the chart and pass it on the command line (`--values /tmp/kube-prometheus-stack.values`).
+For this tutorial we choosed the first method.
 
-```bash
-helm inspect values prometheus-community/kube-prometheus-stack > /tmp/kube-prometheus-stack.values
-```
-
-Open the `/tmp/kube-prometheus-stack.values` file in your favorite editor.
-
-Then search into it for `adminPassword` and replace it with the password you want to use for Grafana.
-
-By default, the Grafana password should be like this:
-
-```yaml
-  adminPassword: prom-operator
-```
-
-Copy and save the Grafana admin password, you will use it later in this tutorial.
-
-You are now ready to install Prometheus and Grafana.
+To install Prometheus and Grafana:
 
 ```bash
 helm install prometheus-community/kube-prometheus-stack \
 --create-namespace --namespace prometheus \
 --generate-name \
---values /tmp/kube-prometheus-stack.values \
 --set prometheus.service.type=LoadBalancer \
 --set prometheus.prometheusSpec.serviceMonitorSelectorNilUsesHelmValues=false \
 --set grafana.service.type=LoadBalancer
+--set grafana.adminpassword=<my cool password>

 As you can see, a new `prometheus` namespace will be created and we specified that we want to deploy a LoadBalancer in order to access externally to Prometheus and Grafana easily.
