-Furthermore, the administrator has to whitelist the applications that guests can use.
-By default settings, avatar, files_external, files_trashbin, files_versions, files_sharing, files_texteditor, activity, firstrunwizard, gallery, notifications, password_policy and oauth2 are allowed.
+An ownCloud Classic (OC10) app that enables sharing files with external users via email address. When a file is shared with a guest, they receive an email invitation with a link to create an account. Guest users have access only to files shared with them and can use a configurable whitelist of allowed apps (such as file viewers, text editors, and activity tracking).
+
+## Getting Started
+
+Enable the app in the ownCloud admin panel:
+
+```bash
+sudo -u www-data php occ app:enable guests
+```
+
+To invite a guest, type their email address in the sharing dialog. The guest receives an email with instructions to create an account. Administrators can configure the allowed apps for guest users in the admin settings.

+### 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.

+## 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: GPL-2.0** (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 GPL dependencies must be replaced or isolated
+- **KDE heritage review**: Any code with KDE-era copyrights requires legal analysis
+- **Complete relicensing**: GPL-2.0 is a strong copyleft license; migration requires full relicensing of all files

+# AI Agent Guidelines for ownCloud Guests
+
+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):** JavaScript
+- **Build system:** Make + Composer + Yarn
+- **Test framework:** PHPUnit
+- **CI system:** GitHub Actions
+
+## Architecture & Key Paths
+
+- `appinfo/` -- App metadata and registration
+- `lib/` -- PHP application logic (guest user management)
+- `js/` -- Frontend JavaScript
+- `css/` -- Stylesheets
+- `templates/` -- PHP templates
+- `l10n/` -- Translations
+- `tests/` -- PHPUnit and acceptance tests
+- `Makefile` -- Build and test targets
+
+## Development Conventions
+- **Branching:** master
+- **Commit messages:** DCO sign-off required (`git commit -s`)
+- **Code style:** PHP-CS-Fixer and PHP_CodeSniffer (`phpcs.xml`, `vendor-bin/owncloud-codestyle`)
+- **PR process:** Open a PR against `master`. All CI checks must pass.
+
+## Build & Test Commands
+```bash
+# Build
+make dist
+
+# Test
+make test
+
+# Lint
+make test-php-style
+```
+
+## Important Constraints
+- All code contributions must be compatible with the **GPL-2.0** 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@<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
