+### Changing Parameters After Deployment
+Some parameters in `values.yaml`, such as `nextcloud.trustedDomains`, are only templated into the container environment during the initial installation.  
+Changes after deployment must be made by redeploying the Helm chart or manually inside the pod using the `occ` command. Example of a manual change:
+
+```bash
+# Add a new trusted domain after deployment
+kubectl exec -it <your-nextcloud-pod> -- /bin/sh -c "php occ config:system:set trusted_domains 2 --value=nextcloud.mydomain2.com"
+```
+
 ## Injecting Additional Manifests (`extraManifests`)
 
 You can inject additional Kubernetes manifests (such as Traefik IngressRoutes, Middlewares, or any custom resources) directly via `values.yaml` using the `extraManifests` value.
