+# ownCloud Docs Main Page
-**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)
-**Table of Contents**
+Antora-based documentation component for the ownCloud documentation landing page. This repository provides the top-level navigation and main page content that serves as the entry point for the published documentation site at [doc.owncloud.com](https://doc.owncloud.com).
-* [Building the Main Page Docs](#building-the-main-page-docs)
-* [General Notes](#general-notes)
-* [Generating the Documentation](#generating-the-documentation)
-* [Target Branch and Backporting](#target-branch-and-backporting)
-* [Branching Workflow](#branching-workflow)
-* [Create a New Version Branch for the docs Main Page](#create-a-new-version-branch-for-the-docs-main-page)
+## Getting Started
-## Building the Main Page Docs
+To preview changes locally:
-The ownCloud Main Page documentation is not built independently. Instead, it is built together with the [documentation](https://github.com/owncloud/docs/). However, you can build a local copy of the ownCloud Server documentation to preview changes you are making.
+```bash
+npm install
+npm run antora-local
+npm run serve
+```
-Whenever a Pull Request of this repo gets merged, it automatically triggers a full docs build.
+This generates a standalone preview at `http://localhost:8080`. For the full site build, merge your changes and the [docs](https://github.com/owncloud/docs) repository will automatically rebuild.
-## General Notes
+## Documentation
-To make life easier, most of the content written in [docs](https://github.com/owncloud/docs#readme) applies also here. For ease of reading, the most important steps are documented here too. For more information see the link provided. Only a few topics of this repo are unique like the branching.

-## Generating the Documentation
+## Part of ownCloud Documentation
-See the [Generating the Documentation](https://github.com/owncloud/docs#generating-the-documentation) in the docs repo for more details as it applies to all documentation repositories.
+This is a content component for the [ownCloud docs](https://github.com/owncloud/docs) Antora build. It provides the main landing page and cross-product navigation. Published documentation is available at [doc.owncloud.com](https://doc.owncloud.com).
-## Target Branch and Backporting
+## Community & Support

+### Workflow
+
+- **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.
+
+## Security
+
+**Do not open a public GitHub issue for security vulnerabilities.**
+
+Report vulnerabilities at **** -- see [SECURITY.md](SECURITY.md).

+## About the ownCloud OSPO
+
+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.

+- **GitHub**:
+- **ownCloud**:
+
+For questions about the OSPO or licensing, contact ospo@kiteworks.com.
+
+### License Migration to Apache 2.0
+
+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).
+
+Individual repositories will migrate as their audit is completed. The LICENSE file
+in each repo reflects its **current** license status (not the target).
+
+**Current license: AGPL-3.0** (Category X per Apache policy -- cannot be included in Apache-2.0 works).
+
+Migration prerequisites for this repository:
+
+- **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 Docs Main Page
+
+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
+
+- `antora.yml` -- Antora component descriptor
+- `modules/` -- AsciiDoc documentation content modules
+- `site.yml` -- Standalone site playbook for local preview
+- `package.json` -- npm scripts
+- `docs/` -- Documentation about branching and versioning
+- `ext-antora/` -- Custom Antora extensions
+- `ext-asciidoc/` -- Custom AsciiDoc extensions
+
+## Development Conventions
+- **Branching:** master
+- **Commit messages:** DCO sign-off required (`git commit -s`)
+- **Code style:** Prettier (for formatting)
+- **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
