+## Migrate From Codeberg
+
+For all users who come from the Codeberg repository (no longer maintained by the original author) 
+it is possible to migrate to this new version of the kube-downscaler by installing the Helm chart in this way:
+
+```bash
+$ helm install kube-downscaler py-kube-downscaler/py-kube-downscaler --set nameOverride=kube-downscaler --set configMapName=kube-downscaler
+```
+
+or extracting and applying the template manually:
+
+```bash
+$ helm template kube-downscaler py-kube-downscaler/py-kube-downscaler --set nameOverride=kube-downscaler --set configMapName=kube-downscaler
+```
+
+Installing the chart in this way will preserve the old nomenclature already present in your cluster
