 ### GitHub Actions Workflow

-`.github/workflows/docker-publish.yml` builds and publishes Docker images for `linux/amd64`, `linux/arm64`, and `linux/arm/v7`:
+Container workflows (amd64 + arm64 only):

-| Trigger | Tags Created |
-|---------|--------------|
-| Release | `X.Y.Z`, `X.Y`, `latest` |
-| Nightly (4 AM UTC) | Rebuilds all version tags + `nightly`, `nightly-YYYYMMDD` |
-| Manual | `sha-xxxxxx` |
-| Pull request | Builds image (linux/amd64) without pushing and runs a smoke test |
-
-**Nightly rebuilds** ensure version tags always include the latest OS security patches. This is a common pattern used by official Docker images (nginx, postgres, node). Users needing reproducibility should pin by SHA digest or use dated nightly tags.
+- `pr.yml`: pull_request lint (actionlint/hadolint), container-relevant path filter, multi-arch build (no push), native image build for report-only Trivy scan.
+- `release.yml`: tag push `vMAJOR.MINOR.PATCH` → push `MAJOR`, `MAJOR.MINOR`, `MAJOR.MINOR.PATCH`, `latest` with SBOM + provenance attestations, Trivy report artifact, cosign keyless signing, and manifest platform verification.
+- `nightly.yml`: scheduled + workflow_dispatch → push `nightly` with SBOM + provenance attestations, Trivy report artifact, cosign keyless signing, and manifest platform verification.

 GitHub Actions use version tags in workflows, and Renovate is configured in `renovate.json` to pin action digests, maintain lockfiles, and auto-merge patch + digest updates once required checks pass (with automatic rebases when behind `main`).

+## Container Images & CI
+
+### Tags and Platforms
+
+- **Release tags** (on `vMAJOR.MINOR.PATCH`): `MAJOR`, `MAJOR.MINOR`, `MAJOR.MINOR.PATCH`, `latest`
+- **Nightly tag**: `nightly`
+- **Platforms**: `linux/amd64`, `linux/arm64`
+
+### Security Artifacts
+
+- **SBOM and provenance** are attached to the pushed images in GHCR (view in the image details/attestations UI).
+- **Vulnerability reports** are uploaded as GitHub Actions artifacts for each release/nightly build.
+
+Example cosign verification (release tag):
+
+```bash
+cosign verify \
+  --certificate-oidc-issuer https://token.actions.githubusercontent.com \
+  --certificate-identity-regexp 'https://github.com/jorijn/meshcore-stats/.github/workflows/release.yml@refs/tags/v1.2.3' \
+  ghcr.io/jorijn/meshcore-stats:1.2.3
+```
+
+### Local Workflow Testing
+
+Prerequisites:
+- Docker Desktop (or Docker Engine) with Buildx enabled
+- QEMU/binfmt installed for multi-arch builds
+
+Commands:
+
+```bash
+# Native-arch build (loads into local Docker)
+make docker-build
+
+# Multi-arch build validation (amd64 + arm64, no push)
+make docker-buildx-all
+```
+
+Use `make docker-buildx-all` for full multi-arch validation.
+
 ### Manual Installation (Alternative)
