+# WARNING: New location storage for the helm chart - How to use
+
+All the helm chart are now stored inside the GitHub Docker registry.
+
+Please use it like so:
+
+## For helmfile.yaml
+
+```
+chart: oci://ghcr.io/geonetwork/geonetwork-helm-charts/myhelmchart
+version: X.X.X
+```
+
+You don't need to include this anymore:
+```
+repositories:
+  - name: geonetwork-helm-charts
+    url: https://helm-charts.geonetwork-opensource.org
+```
+
+Make sure to migrate to this new way of working.
