+This is the way to go if you want to use the packaged chart as is. If you'd like to make changes before installing, refer to the next section.

 Add our helm repository[^1]:
 
 ```console
 helm repo add nextcloud-onlyoffice https://open.greenhost.net/api/v4/projects/1/packages/helm/stable
 ```
 
+Then install the chart:
+
+```console
+helm install --wait -f values-local.yaml my-nextcloud nextcloud-onlyoffice/nextcloud-onlyoffice
+```
+
+**The `--wait` is important!** We need that because of how [helm chart
+hooks](https://helm.sh/docs/topics/charts_hooks/) work:
+
+> Note that if the --wait flag is set, the library will wait until all resources
+> are in a ready state and will not run the post-install hook until they are
+> ready.
+
+The job in this chart needs the Nextcloud pod to be in a ready state before
+being executed.
+
+### Install from a local repo
