+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Repository Overview
+
+This is the **Grafana Community Helm Charts** repository — a collection of Helm charts for Grafana ecosystem components. Charts are published to both a Helm repository (`grafana-community`) and as OCI artifacts on `ghcr.io`.
+
+## Charts
+
+All charts live under `charts/` with a subfolder for each chart.  The subfolder names must match the chart name as described in the Chart.yaml file `.name`.
+
+Each chart follows standard Helm structure (`Chart.yaml`, `values.yaml`, `templates/`). Some charts will organize components into subdirectories (e.g., `templates/compactor/`, `templates/ingester/`).
+
+## pre-commit testing
+
+### helm-unittests
+
+Pull Requests against this repository require that all charts which implement helm-unittests(https://github.com/norwoodj/helm-docs) must pass all of their unittests.  This can be done via a single command run from the repository root:
+
+```bash
+make helm-unittest
+```
+
+### helm-docs
+
+Pull Requests against this repository require that all charts which implement helm-docs(https://github.com/norwoodj/helm-docs) must re-generate their README.md files after modifying `values.yaml` or `README.gotmpl`.  This can be done via a single command run from the repository root:
+
+```bash
+make helm-docs
+```
+
+## Contributing Conventions
+
+- **One chart per PR**: CI enforces that PRs only change a single chart.
+- **PR title format**: Must start with `[chart-name] ` (e.g., `[grafana] Add new feature`).
+- **Version bumps**: Every chart change (excluding files listed in `.helmignore`) requires a semver version bump in `Chart.yaml`. Major bumps for breaking changes.
+- **DCO sign-off**: Commits must include `Signed-off-by` line (`git commit -s`).
+- **Squash merge only**: The repo only allows squash merges.
+- **CODEOWNERS/MAINTAINERS**: Auto-generated from `Chart.yaml` maintainer entries by `scripts/check-codeowners.sh` and `scripts/check-maintainers.sh`. Do not edit `.github/CODEOWNERS` or `MAINTAINERS.md` directly.
+- **Minimum Kubernetes version**: Charts target `^1.25.0-0` (`kubeVersion` in `Chart.yaml`).
+
+## Dependency Management
+
+Renovate manages automated dependency updates. Charts with subchart dependencies (e.g., `tempo-distributed` depends on `minio`, `grafana-agent-operator`, `rollout-operator`) declare them in `Chart.yaml`. Dependency repos used in CI/release:
+
+```
+bitnami, grafana, grafana-community, prometheus-community, minio
+```
