+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+This repository packages [nelm](https://github.com/werf/nelm) (a Helm 3 alternative Kubernetes deployment tool) into multi-architecture Docker images. It does not contain nelm source code—only a Dockerfile and CI/CD workflows to automate building and publishing images.
+
+## Repository Structure
+
+- `Dockerfile` - Multi-stage build that downloads nelm and kubectl binaries with GPG verification
+- `.github/workflows/build-and-publish.yml` - Builds and publishes multi-arch images (amd64/arm64) to GHCR and Docker Hub
+- `.github/workflows/update-nelm.yml` - Daily cron job that discovers new nelm releases and triggers builds
+
+## Building Locally
+
+```bash
+# Build for current architecture
+docker build -t nelm .
+
+# Build with specific nelm version
+docker build --build-arg NELM_VERSION=1.12.2 -t nelm .
+```
+
+## Image Publishing
+
+Images are published to:
+- `ghcr.io/hsw/nelm`
+- `hsww/nelm` (Docker Hub)
+
+Tags follow semver: `1.12.2`, `1.12`, `1`, plus quality labels from upstream (`ea`, `stable`, `rock-solid`).
+
+## Workflow Behavior
+
+The `update-nelm.yml` workflow:
+1. Fetches all stable releases from werf/nelm
+2. Checks which versions already exist in the container registry
+3. Triggers `build-and-publish.yml` for missing versions (max 10 per run)
+4. Only builds versions newer than or equal to the newest stable/rock-solid release
