 Install Qovery on your Kubernetes cluster.

-helm upgrade --install -n qovery -f values-demo.yaml qovery qovery/qovery
+helm upgrade --install --wait --atomic --create-namespace -n qovery -f <your-values-file.yaml> \

 * `-n qovery`: the namespace where Qovery and its dependencies will be installed
+* `--set...`: override (only for the first deployment time, if you want to use Cert-Manager) to let cert-manager install its CRDs
 * `-f your-values-file.yaml`: the values file you've downloaded, overrided with the Qovery config and your custom config
 * `qovery/qovery`: name of the chart to deploy
 * `qovery`: name of the release
 
+If you want to use Cert-Manager, you can remove the `--set...` for the future updates (or if already installed):
+```bash
+helm upgrade --install --create-namespace -n qovery -f <your-values-file.yaml> qovery qovery/qovery
+```
+
 That's it, you can now use Qovery on your own Kubernetes cluster!
