+## Deploy CRAB
+
+At the moment CRAB team is transitioning to using helm. However, we do noy like
+to use helm for deployment. See this 
+[comment](https://github.com/dmwm/CRABServer/issues/7843#issuecomment-2025085120)
+for some context.
+
+We like to use helm for templating, using the helm charts to generate the 
+manifest file, then applying it with `kubectl apply`.
+
+We therefore ask cmsweb operators to deploy crab with the following procedure:
+
+Generate the manifest with
+
+```bash
+# testbed
+helm template crabserver . -f values.yaml -f values-testbed.yaml > ../../kubernetes/cmsweb/services/crabserver.yaml
+
+# prod
+helm template crabserver . -f values.yaml -f values-prod.yaml > ../../kubernetes/cmsweb/services/crabserver.yaml
+```
+
+Then to deploy it with the usual `deploy-srv.sh` script
+
+```bash
+# testbed
+./scripts/deploy-srv.sh crabserver v3.231006 preprod
+
+# prod
+./scripts/deploy-srv.sh crabserver v3.231006 prod
+```
+
+Changes to `../../kubernetes/cmsweb/services/crabserver.yaml` should not be committed.
