-## Info
-
-Note that in directory `preview-site-src`, the `404.html` file is on purpose but `index.html` file is for internal testing purposes only. The file is recreated in the `public/` directory on each `preview` build and served from there. There is no need to change or copy it.
+
-## Contributing
-
-If you want to make changes, create a "_feature_" branch off of master, make the required changes, and then create a Pull Request (PR) against the _master_ branch.
-If the PR is accepted and merged, a new `ui-bundle.zip` package file will be created and published to `https://minio.owncloud.com/documentation/ui-bundle.zip` as part of the build pipeline.
+[](LICENSE) [](https://kiteworks.com/opensource)
-## Prerequisites
+A custom Antora UI theme for the official ownCloud documentation. This repository is based on the [Antora Default UI](https://gitlab.com/antora/antora-ui-default) and provides the HTML templates, CSS styles, JavaScript behavior, and assets that define the look and feel of the published documentation at [doc.owncloud.com](https://doc.owncloud.com).
-To preview the UI changes or to create a local version of a `ui-bundle.zip`, you need to install the following software on your computer.
+## Getting Started
-- [git][link-git] (command: `git`)
-- [Node][link-node] (command: `node`)
-- [Gulp CLI][link-gulp-cli] (command: `gulp`)
+Install dependencies and preview the UI:
-### git
+```bash
+npm install
+npm run preview
+```
-First, make sure you have git installed.
+To build the UI bundle for production:
-```Shell
-git --version
+```bash
+npm run bundle
```
-If git is not installed, download and install the [git package][link-git-package] for your system.
+The generated `ui-bundle.zip` in `build/` is consumed by the Antora documentation build.
-### Node
+## Documentation
-Next, make sure that you have Node installed.
+- [Main Documentation Build](https://github.com/owncloud/docs)
+- [Antora UI Documentation](https://docs.antora.org/antora-ui-default/)
-```Shell
-node --version
-```
+## Part of ownCloud Documentation
-If this command fails with an error, you don't have Node installed.
-While you can install Node from the official packages, we strongly recommend that you use [NVM][link-nvm] (Node Version Manager) to install and manage Node.
+This repository provides the UI bundle consumed by the [ownCloud docs](https://github.com/owncloud/docs) Antora build. The output `ui-bundle.zip` is referenced in the docs site playbook. Published documentation is available at [doc.owncloud.com](https://doc.owncloud.com).
-Follow the [NVM installation instructions][link-nvm-installation-instructions] to set up NVM on your machine.
-Once you've installed NVM, open a new terminal and install Node using the following command:
+## Development Reference
-```Shell
-nvm ls-remote | grep "Latest LTS"
+Development workflow and build tooling for the UI bundle:
- ...
- v18.20.4 (Latest LTS: Hydrogen)
- v20.18.1 (Latest LTS: Iron)
- v22.22.0 (Latest LTS: Jod)
- v24.14.0 (Latest LTS: Krypton)
-```
+### Prerequisites
-Then install a suitable LTS version, preferrable > v20. You can install as many versions as you like or need, see example below.
+- [Git](https://git-scm.com/)
+- [Node.js](https://nodejs.org/) (v22 LTS recommended; use [NVM](https://github.com/creationix/nvm) to manage versions)
+- npm >= 11.11.0
-```Shell
-nvm install 22.22.0
-```
+### Available npm Commands
-List the installed versions
+| Command | Description |
+|---|---|
+| `npm run lint` | Lint the UI bundle definition |
+| `npm run bundle` | Generate a `ui-bundle.zip` for local use |
+| `npm run preview` | Preview the bundle using a demo Antora build at `http://localhost:5252` |
-```Shell
-nvm ls
--> v22.22.0
-default -> 22.22.0 (-> v22.22.0)
+### Preview with ownCloud Documentation
-...
-```
+To preview UI changes using the actual ownCloud documentation instead of demo content:
-**Info:** The backend to push to the web also uses node v22, see the `.drone.star` file. It is recommended to stay with the same release if possible.
+1. Build a local `ui-bundle.zip` with `npm run bundle`
+2. Switch to the target documentation repository
+3. Run `npm run antora-dev-bundle` in the docs repo
-Switch to a specific installed version of Node at any time, use the following command:
+See the [Generating the Documentation](https://github.com/owncloud/docs#generating-the-documentation) guide for details.
-```Shell
-nvm use 22.22.0
-```
+### Contributing Workflow
-**Important:** If you have additional concurrent terminals open, you must close these terminals first and reopen them to use the new setup.
+Create a feature branch off `master`, make changes, and submit a PR. When merged, the CI pipeline automatically builds and publishes a new `ui-bundle.zip` to `https://minio.owncloud.com/documentation/ui-bundle.zip`.
-To make a particular Node version default in new terminals, type:
+## Community & Support
-```Shell
-nvm alias default 22.22.0
-```
+**[Star](https://github.com/owncloud/docs-ui)** this repo and **Watch** for release notifications!
-Now that you have Node installed, you can proceed with installing the Gulp CLI and npm.

-### Update npm
+## Contributing
-`npm` should be at minimum version 11.11.0\
-You can check this with `npm -v`. If an update is needed, simply run teh following command. Replace `latest` with a version if you want to lock it.
+We welcome contributions! Please read the [Contributing Guidelines](CONTRIBUTING.md)
+and our [Code of Conduct](CODE_OF_CONDUCT.md) before getting started.
-```Shell
-npm install -g npm@latest
-```
+### Workflow
-### Install Dependencies
+- **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.
-Finally, run the following command to install all dependencies:
+## Security
-```Shell
-npm install
-```
+**Do not open a public GitHub issue for security vulnerabilities.**
-### Add Packages
+Report vulnerabilities at **** -- see [SECURITY.md](SECURITY.md).
-If a new package needs to be added, type the following:
+Bug bounty: [YesWeHack ownCloud Program](https://yeswehack.com/programs/owncloud-bug-bounty-program)
-```Shell
-npm -i
-```
-
-## Prepared npm Commands
+## License
-To see all prepared npm commands, run the following command `npm run`. This will output all commands with their settings, though this makes readability not easy. See the [npm documentation](https://docs.npmjs.com/cli/v11/using-npm/scripts) for more information.
+This project is licensed under the [AGPL-3.0](LICENSE).
-Here is the list of commands and when to use them:
+## About the ownCloud OSPO
-* `npm run lint`
-Lint the UI bundle definition
-* `npm run bundle`
-Generate a new `ui-bundle.zip` file for local use
-* `npm run preview`
-Preview the bundle using the gulp. This previews a demo Antora build.
+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.
-## Preview
+- **OSPO Home**:
+- **GitHub**:
+- **ownCloud**:
-### Preview Changes Using the ownCloud Documentation
+For questions about the OSPO or licensing, contact ospo@kiteworks.com.
-If you want to preview your changes to the UI using the ownCloud documentation instead of demo content then you need to build a local copy of `ui-bundle.zip` and use it when generating the ownCloud documentation in your local development machine.
+### License Migration to Apache 2.0
-* First create a local `ui-bundle.zip` with the command described above.
-* Then change into the respective documentation repository and run `npm run antora-dev-bundle`.
-See the [Generating the Documentation](https://github.com/owncloud/docs#generating-the-documentation) description for more details.
+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).
-### Previewing Changes using a Demo Antora Build
+Individual repositories will migrate as their audit is completed. The LICENSE file
+in each repo reflects its **current** license status (not the target).
-The following example runs a demo Antora **build** (_not ownCloud_) for the documentation site which can be **accessed** on your local development machine at `http://localhost:5252`.
+**Current license: AGPL-3.0** (Category X per Apache policy -- cannot be included in Apache-2.0 works).
-To view your changes as you are working on them, run the following command:
+Migration prerequisites for this repository:
-```Shell
-npm run preview
-```
+- **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 UI
+
+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):** CSS
+- **Build system:** npm (Gulp)
+- **Test framework:** Gulp lint task
+- **CI system:** GitHub Actions
+
+## Architecture & Key Paths
+
+- `src/` -- UI source files (Handlebars templates, CSS, JS)
+- `tasks/` -- Gulp task definitions
+- `gulpfile.js` -- Gulp build configuration
+- `preview-site-src/` -- Preview site source for local testing
+- `package.json` -- npm scripts
+- `docs/` -- Documentation about the UI
+
+## Development Conventions
+- **Branching:** master
+- **Commit messages:** DCO sign-off required (`git commit -s`)
+- **Code style:** Not detected
+- **PR process:** Open a PR against `master`. All CI checks must pass.
+
+## Build & Test Commands
+```bash
+# Build
+npm run bundle
+
+# Test
+npm run lint
+
+# Lint
+npm run lint
+```
+
+## 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
