+The Announcement Center is an ownCloud Server app that allows administrators to publish announcements visible to all users. Announcements appear on a dedicated front page accessible from the app launcher, and users are automatically notified via the activity stream. The app depends on the [notifications](https://github.com/owncloud/notifications) backend for delivering notifications.
 
----
+## Part of Classic (OC10)
 
-## Screenshots
+Announcement Center is an app for [ownCloud Server (Classic)](https://github.com/owncloud/core). It is available on [Docker Hub as part of the ownCloud Server image](https://hub.docker.com/r/owncloud/server).
 
-### Announcements front page (the "Add announcement" form is admin only)
+## Getting Started
 
-![Announcement Center Frontpage](docs/AnnouncementCenterFrontpage.png)

+  ```
+  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.

+## 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.

+
+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 Announcement Center
+
+This file provides context for AI coding agents (Claude Code, GitHub Copilot, Cursor, etc.) working in this repository.
+
+## Repository Overview
+- **Product family:** Classic (OC10)
+- **Primary language(s):** PHP, JavaScript
+- **Build system:** Composer, Make
+- **Test framework:** PHPUnit
+- **CI system:** GitHub Actions
+
+## Architecture & Key Paths
+- `lib/` - PHP application logic
+- `appinfo/` - ownCloud app metadata and registration
+- `templates/` - Server-side templates
+- `js/` - Frontend JavaScript
+- `css/` - Stylesheets
+- `l10n/` - Translations
+- `img/` - App icons
+- `tests/` - PHPUnit test suite
+- `docs/` - Screenshots and documentation
+- `Makefile` - Build and test automation
+- `composer.json` - PHP dependencies
+- `phpstan.neon` - PHPStan configuration
+- `phpunit.xml` - PHPUnit configuration
+- `CONTRIBUTING.md` - Contribution guidelines
+
+## Development Conventions
+- **Branching:** master
+- **Commit messages:** DCO sign-off required (`git commit -s`)
+- **Code style:** PHP_CodeSniffer, ownCloud coding standard
+- **PR process:** Open a PR against master. All CI checks must pass.
+
+## Build & Test Commands
+```bash
+# Build
+make
+
+# Test
+make test-php-unit
+
+# Lint
+make test-php-style
+
+# Fix code style
+make test-php-style-fix
+
+# Static analysis
+make test-php-phpstan
+```
+
+## 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
+- This app depends on the `notifications` app backend
+
+
+## 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.
+
+### 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
