+## About this repository
+
+This repository builds the official **ownCloud base** Docker image
+([`owncloud/base`](https://hub.docker.com/r/owncloud/base)). It is not an
+application codebase — it layers ownCloud runtime defaults and an optional
+root-filesystem overlay on top of the
+[`owncloud/php`](https://github.com/owncloud-docker/php) image. See the
+[README](README.md) for build details, supported tags and usage.
+
+## Pull requests
+
+- **Rebase Early, Rebase Often!** We use a rebase workflow. Rebase on the target
+ branch before submitting a PR; do not create merge commits.
+- **Signed commits**: All commits **must** be PGP/GPG signed. See
+ [GitHub's signing guide](https://docs.github.com/en/authentication/managing-commit-signature-verification).
+- **DCO Sign-off**: Every commit must carry a `Signed-off-by` line:
+ ```
+ git commit -S -s -m "your commit message"
+ ```
+- **Conventional Commits**: PR titles must follow the
+ [Conventional Commits](https://www.conventionalcommits.org/) format — this is
+ enforced by CI, and the PR title becomes the squash-merge commit message.
+- **GitHub Actions Policy**: Workflows may only use actions that are (a) owned by
+ `owncloud`, (b) created by GitHub (`actions/*`), or (c) verified in the GitHub
+ Marketplace. Pin all actions to their full commit SHA.

+
+## Repository Overview
+
+This repository builds the official **ownCloud base** Docker image
+(`owncloud/base` on Docker Hub). It is the ownCloud-specific foundation layer:
+it sits on top of [`owncloud/php`](https://github.com/owncloud-docker/php) and
+adds ownCloud runtime defaults, environment-variable handling and an optional
+root-filesystem overlay. Higher-level images such as
+[`owncloud/server`](https://github.com/owncloud-docker/server) build `FROM` it.
+Images are multi-architecture and built via GitHub Actions.
+
+- **Classification:** Docker image build (base layer)
+- **Activity Status:** Active
+- **License:** MIT
+- **Language:** Dockerfile, Shell
+
+## Architecture & Key Paths
+
+- `v20.04/`, `v22.04/`, `v24.04/` — one directory per Ubuntu base release
+ - `/Dockerfile.multiarch` — image definition (`FROM owncloud/php:`)
+ - `/overlay/` — files copied into the image root (`ADD overlay /`)
+- `ENVIRONMENT.md` — full reference of the environment variables this image
+ consumes (the README links here for the complete list)
+- `CLAUDE.md` — repository overview / instructions for Claude Code
+- `.github/workflows/main.yml` — **active** CI (build, smoke test, scan, publish)
+- `.github/workflows/lint-pr-title.yml` — Conventional-Commit PR-title enforcement
+- `.github/dependabot.yml` — weekly GitHub Actions dependency updates
+- `.renovaterc.json` — Renovate preset for Docker digest updates
+- `.editorconfig` — formatting rules (2-space indent, LF, trailing newline)
+- `.trivyignore` — accepted-CVE exclusions for the Trivy scan
+- `CHANGELOG.md` — flat, date-based changelog at repo root
+- `LICENSE` — MIT
+
+## Build & CI
+
+There is no local application build (no Node/pnpm/Make toolchain). The image is
+built by `.github/workflows/main.yml`, which calls reusable workflows hosted in
+[`owncloud-docker/ubuntu`](https://github.com/owncloud-docker/ubuntu):
+
+- Matrix builds the supported Ubuntu releases (`22.04`, `24.04`), each via
+ `v/Dockerfile.multiarch`.
+- Smoke test: `php -r "echo 'OK';" | grep -q OK`.
+- Trivy vulnerability scan (`.trivyignore`).
+- On `master`: push to Docker Hub and sync the README as the image description.
+
+To build locally:
+
+```bash
+docker build -f v22.04/Dockerfile.multiarch v22.04
+```
+
+The image exposes port `8080` and declares volume `/mnt/data`.
+
+## Development Conventions
+
+- Date-based `CHANGELOG.md` at repo root — **not** a `changelog/unreleased/`
+ directory. Prepend a new `## YYYY-MM-DD` section for notable changes.
+- Conventional-Commit PR titles, enforced by `lint-pr-title.yml`.
+- `.editorconfig` governs formatting.
+- GitHub Actions are pinned to full commit SHAs.
+
+## OSPO Policy Constraints
+
+### GitHub Actions
+- **Only** use actions owned by `owncloud`, created by GitHub (`actions/*`),
+ verified on the GitHub Marketplace, or verified by the ownCloud Maintainers.
+- Pin all actions to their full commit SHA (not tags): `uses: actions/checkout@ # vX.Y.Z`.
+- Never introduce actions from unverified third parties.
+
+### Dependency Management
+- Dependabot is configured for GitHub Actions updates; Renovate handles Docker
+ base-image digest updates.
+- Review and merge dependency PRs as part of regular maintenance.
+
+### Git Workflow
+- **Rebase policy**: Always rebase; never create merge commits.
+- **Signed commits**: All commits **must** be PGP/GPG signed (`git commit -S`).
+- **DCO sign-off**: Every commit needs a `Signed-off-by` line (`git commit -s`).
+- **Conventional Commits & Squash Merge**: PR titles must follow
+ [Conventional Commits](https://www.conventionalcommits.org/); the PR title
+ becomes the squash-merge commit message and is enforced by CI.
+
+## Context for AI Agents
+
+- This is a small Docker-image packaging repo, not an application codebase.
+- The `v*/` directories are near-identical; changes usually apply to all of them.
+- The `overlay/` directories are the image root filesystem — add files there to
+ ship them in the image.
+- The active build system is GitHub Actions (`main.yml`).
+- The README is published verbatim as the Docker Hub image description — keep it
+ accurate and self-contained.
+- License is **MIT** (permissive, already compatible with Apache-2.0); no
+ copyleft dependency audit is required for relicensing.
