# ownCloud Documentation
-**IMPORTANT**
+
-Since April 2026, this repository requires [Commit Signing](https://docs.github.com/articles/about-gpg) and uses [Conventional Commits](https://www.conventionalcommits.org) for commits and the Pull Request title.
+[](LICENSE) [](https://kiteworks.com/opensource)
-**Overview**
+The central Antora-based documentation site for all ownCloud products. This repository contains the site playbook (`site.yml`), Antora and AsciiDoc extensions, shared resources, fonts, and build scripts that aggregate content from all `docs-*` component repositories into a single published documentation site at [doc.owncloud.com](https://doc.owncloud.com).
-1. The platform and tools used to build the documentation is [Antora](./docs/what-is-antora.md).
-2. The file format that the documentation is written in is [AsciiDoc](./docs/what-is-asciidoc.md).
-3. The UI & UX of the documentation can be found at [docs-ui](https://github.com/owncloud/docs-ui)

+We welcome contributions! Please read the [Contributing Guidelines](CONTRIBUTING.md)
+and our [Code of Conduct](CODE_OF_CONDUCT.md) before getting started.
-## Generating the Documentation
+### Workflow
-**IMPORTANT**
-We use `node 22 LTS`. In case you used a lower node version for your local doc repos, you must upgrade them **all**. See the link below for details.
+- **Rebase Early, Rebase Often!** We use a rebase workflow. Always rebase on the target branch before submitting a PR.
+- **Dependabot**: Automated dependency updates are managed via Dependabot. Review and merge dependency PRs promptly.
+- **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"
+ ```
+- **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.
-**IMPORTANT**
-We use `Antora 3.1.14` and npm instead of yarn. In case you used a lower Antora version for your local doc repos, you must upgrade them **all** by syncing them and running `npm install` in each doc repo.
+## Security
-To generate and view the documentation locally or planning major changes, refer to the [Building the Documentation guide](./docs/build-the-docs.md).
+**Do not open a public GitHub issue for security vulnerabilities.**
-## Common Content and Styling the Documentation
+Report vulnerabilities at **** -- see [SECURITY.md](SECURITY.md).
-If you want to suggest an improvement to the ownCloud documentation theme, such as the layout, the header or the footer text, or if you find a bug, all the information that you need is in the `docs-ui` repository. Changes made in `docs-ui` are valid for the whole documentation.
+Bug bounty: [YesWeHack ownCloud Program](https://yeswehack.com/programs/owncloud-bug-bounty-program)
-Please read how to test un-merged [docs-ui](./docs/test-ui-bundle.md) changes with content from the ownCloud documentation.
+## License
-## Best Practices and Tips
+This project is licensed under the [AGPL-3.0](LICENSE).
-Refer to [Best Practices and Tips for writing in AsciiDoc](./docs/best-practices.md) for more information.
+## About the ownCloud OSPO
-To check for broken links manually, see [install and use a broken-link-checker](./docs/checking-broken-links.md).
+The [Kiteworks Open Source Program Office](https://kiteworks.com/opensource), operating under
+the [ownCloud](https://owncloud.com) brand, launched on May 5, 2026, to steward the open source
+ecosystem around ownCloud's products. The OSPO ensures transparent governance, license compliance,
+community health, and sustainable collaboration between the open source community and
+[Kiteworks](https://www.kiteworks.com), which acquired ownCloud in 2023.
-## Target Branch and Backporting
+- **OSPO Home**:
+- **GitHub**:
+- **ownCloud**:
-Please always do your changes in `master` and backport them to the relevant branches.
-The **ONLY** reason for doing a PR in a branch directly is, to fix an issue which is
-_only_ present in that particular branch! When creating a PR and it is necessary to backport,
-document in the PR to which branches a backport is needed.
+For questions about the OSPO or licensing, contact ospo@kiteworks.com.
-When backporting, consider using the [backport script](./docs/getting-started.md#backporting)
-which eases life a lot and speeds up the process. It is also very beneficial when using the
-extended code provided, because a clear naming structure of the backport PR is generated automatically.
+### License Migration to Apache 2.0
-## When Does a Change Get Published to the Docs Web Site?
+The OSPO is driving a strategic relicensing of ownCloud repositories toward the
+[Apache License 2.0](https://www.apache.org/licenses/LICENSE-2.0), following
+the [Apache Software Foundation's third-party license policy](https://www.apache.org/legal/resolved.html).
-Changes made will get published to the web under the following conditions:
+Individual repositories will migrate as their audit is completed. The LICENSE file
+in each repo reflects its **current** license status (not the target).
-1. A merge in a component to one of the defined version branches triggers as a last step a master branch build.
-2. A merge to master triggers a site build which then pushes all versions defined in site.yml.
+**Current license: AGPL-3.0** (Category X per Apache policy -- cannot be included in Apache-2.0 works).
-## Create a New Version Branch for Docs
+Migration prerequisites for this repository:
-Please refer to [Create a New Version Branch for Docs](./docs/new-version-branch.md) for more information.
-
-## HTML to PDF
-
-At the moment, creating a pdf is dropped from the build process but can be re-implemented if required.
+- **CLA/DCO coverage**: All past contributors must have signed agreements permitting relicensing
+- **Copyleft dependency audit**: All AGPL/GPL dependencies must be replaced or isolated
+- **KDE heritage review**: Any code with KDE-era copyrights requires legal analysis
+- **Complete relicensing**: AGPL-3.0 is a strong copyleft license; migration requires full relicensing of all files, not just a header change

+# AI Agent Guidelines for ownCloud Documentation
+
+This file provides context for AI coding agents (Claude Code, GitHub Copilot, Cursor, etc.) working in this repository.
+
+## Repository Overview
+- **Product family:** Documentation
+- **Primary language(s):** JavaScript
+- **Build system:** npm (Antora)
+- **Test framework:** broken-link-checker
+- **CI system:** GitHub Actions
+
+## Architecture & Key Paths
+
+- `site.yml` -- Antora playbook defining all content sources
+- `package.json` -- npm scripts for building and serving
+- `ext-antora/` -- Custom Antora extensions
+- `ext-asciidoc/` -- Custom AsciiDoc extensions
+- `docs/` -- Documentation about the docs build system itself
+- `resources/` -- Shared resources
+- `fonts/` -- Custom fonts
+- `supplemental/` -- Supplemental UI files
+- `book_templates/` -- PDF book templates
+
+## Development Conventions
+- **Branching:** master
+- **Commit messages:** DCO sign-off required (`git commit -s`)
+- **Code style:** Prettier (`.prettierrc` or similar config present)
+- **PR process:** Open a PR against `master`. All CI checks must pass.
+
+## Build & Test Commands
+```bash
+# Build
+npm run antora
+
+# Test
+npm run linkcheck
+
+# Lint
+Not detected (Prettier config present for formatting)
+```
+
+## Important Constraints
+- All code contributions must be compatible with the **AGPL-3.0** license
+- Do not introduce new **copyleft-licensed dependencies** (GPL, AGPL, LGPL, MPL) without explicit discussion in an issue first. This is especially important for repos migrating to Apache 2.0.
+- Do not introduce new dependencies without discussion in an issue first
+
+
+## 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 automated dependency updates.
+- Review and merge Dependabot PRs as part of regular maintenance.
+- Do not introduce new dependencies without discussion in an issue first.
+
+### Git Workflow
+- **Rebase policy**: Always rebase; never create merge commits. Use `git pull --rebase` and `git rebase` before pushing.
+- **Signed commits**: All commits **must** be PGP/GPG signed (`git commit -S -s`).
+- **DCO sign-off**: Every commit needs a `Signed-off-by` line (`git commit -s`).
+- **Conventional Commits & Squash Merge**: Use the [Conventional Commits](https://www.conventionalcommits.org/) format where the repository enforces it. Many repos use squash merge, where the PR title becomes the commit message on the default branch — apply Conventional Commits format to PR titles as well. A reusable GitHub Actions workflow enforces this.
+
+## Context for AI Agents
+- Match existing code style
+- Do not refactor unrelated code in the same PR
+- Write tests for new functionality
+- Keep PRs focused and atomic
