+This repository manages two Helm charts (e.g., `code-server-chart`, `vllm-serve`) and automates packaging and publishing on every `git push` (local pre-push hook only; no CI runner required).
 
 ## How it works
 
 - Local pre-push hook runs `scripts/helm_publish.sh` to `helm package` and `helm push` all charts found under this folder (directories containing a `Chart.yaml`).
-- A Gitea Actions workflow at `.gitea/workflows/helm-publish.yml` does the same on the server side for each push.
+  - If any chart fails to package/push, the Git push is aborted.
