+## About this repository
+
+This repository builds the official **ownCloud Ubuntu** Docker image
+([`owncloud/ubuntu`](https://hub.docker.com/r/owncloud/ubuntu)) on top of the
+[official Ubuntu](https://hub.docker.com/_/ubuntu) image. It is the foundation
+layer for the rest of the ownCloud Docker image stack. It also **hosts the
+shared reusable GitHub Actions workflows** (`docker-build.yml`,
+`docker-build-native.yml`, `docker-hub-desc.yml`, `lint-editorconfig.yml`,
+`lint-pr-title.yml`) that the other `owncloud-docker` repositories call. 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 Ubuntu** Docker image
+(`owncloud/ubuntu` on Docker Hub) on top of the
+[official Ubuntu](https://hub.docker.com/_/ubuntu) image. It is the base of the
+ownCloud Docker image stack — [`owncloud/php`](https://github.com/owncloud-docker/php)
+builds `FROM` it. It **also hosts the shared reusable GitHub Actions workflows**
+that every other `owncloud-docker` image repository calls. Images are
+multi-architecture and built via GitHub Actions.
+
+- **Classification:** Docker image build (base layer) + shared CI workflows
+- **Activity Status:** Active
+- **License:** MIT
+- **Language:** Dockerfile, Shell, GitHub Actions YAML
+
+## Architecture & Key Paths
+
+- `v22.04/`, `v24.04/` — one directory per Ubuntu release
+  - `<version>/Dockerfile.multiarch` — image definition (`FROM ubuntu:<version>`)
+  - `<version>/overlay/` — files copied into the image root (`ADD overlay /`)
+- `.github/workflows/` — **the shared reusable workflows for the whole org:**
+  - `docker-build.yml` — cross-compiled multi-arch build, smoke test, Trivy scan,
+    publish (called by `base`, `php`, `server`)
+  - `docker-build-native.yml` — native per-arch build variant (called by `ocis`)
+  - `docker-hub-desc.yml` — sync README to the Docker Hub image description
+    (runs `markdown-link-check` on `README.md`)
+  - `lint-editorconfig.yml` — editorconfig-checker lint
+  - `lint-pr-title.yml` — Conventional-Commit PR-title enforcement
+  - `main.yml` — this repo's own CI, which also self-tests the reusable workflows
+- `.github/dependabot.yml` — weekly GitHub Actions dependency updates
+- `.github/settings.yml` — repository settings management
+- `.renovaterc.json` — Renovate preset for Docker digest updates (Ubuntu major/
+  minor bumps disabled)
+- `.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. `main.yml` builds the `owncloud/ubuntu`
+image via its own reusable workflows and additionally self-tests the native
+multi-arch workflow (`build-native`, which never publishes):
+
+- Matrix builds `22.04` and `24.04`, each via `v<version>/Dockerfile.multiarch`.
+- Smoke test asserts `/etc/os-release`'s `VERSION_ID` matches the tag.
+- Trivy vulnerability scan (`.trivyignore`).
+- On `master`: push to Docker Hub and sync the README as the image description.
+
+**All GitHub Actions inside the reusable workflows are pinned to full commit
+SHAs** (e.g. `actions/checkout@<SHA> # v7.0.0`). When updating an action, keep
+the `# vX.Y.Z` comment in sync with the pinned SHA.
+
+To build locally:
+
+```bash
+docker build -f v24.04/Dockerfile.multiarch v24.04
+```
+
+## 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@<SHA> # vX.Y.Z`.
+- Never introduce actions from unverified third parties.
+- Because this repo hosts the shared reusable workflows, changes here affect
+  every downstream image repository — review action bumps carefully.
+
+### 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 that **also owns the org's shared
+  CI workflows** — treat `.github/workflows/*.yml` as a public interface.
+- The two `v*/` directories are near-identical; changes usually apply to both.
+- 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.
