+You can update the Backend by following those steps:
+
+1. Merge the Pull-Request

+4. Open a Pull-Request to adjust the kustomization config to the new tag from step 3. https://github.com/opentelekomcloud-infra/system-config/blob/main/kubernetes/circle-partner-navigator/base/kustomization.yaml#L14

+Updating the Frontend
+---------------------
+
+You can update the Frontend by following those steps:
+
+1. Merge the Pull-Request
+2. Tag the desired commit and push the tag to Github. It should be visible afterwards on this page: https://github.com/opentelekomcloud-infra/circle-partner-navigator-frontend/tags
+3. Wait at least 10 minutes
+4. Open a Pull-Request to adjust the kustomization config to the new tag. https://github.com/opentelekomcloud-infra/system-config/blob/main/kubernetes/circle-partner-navigator/base/kustomization.yaml#L16
+5. Merge this Pull-Request and wait 10 minutes.
+
+Be aware that updating the Frontend will also pull the data from the Backend again and as a result will also update the partner data on the website.
