-The original text editor app for ownCloud, based on [Ace](http://ace.c9.io/).
+The original text editor app for ownCloud Classic (OC10), built on the [Ace](http://ace.c9.io/) code editor. It provides syntax highlighting, syntax checking, autosave, and a responsive design optimized for both desktop and mobile. Users can edit supported text file types directly in the browser by clicking on them in the Files app.
-Features:
- - Syntax highlighting
- - Autosave
- - Syntax checking
- - Responsive design (optimised on mobile and desktop)
+## Getting Started
-## Install
-Simply copy the `files_texteditor` folder into the `apps` directory and enable the app within the ownCloud settings.
+Copy the `files_texteditor` folder into the ownCloud `apps` directory and enable it:
-## Usage
-To use the editor, click on a [supported file](https://github.com/owncloud/files_texteditor/blob/master/js/editor.js#L6) within the Files app and the file will be loaded into the editor. Saving is automatic, but can also be triggered manually with `Ctrl+S` or `Cmd+S`.

+- **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.
+
+- **OSPO Home**:
+- **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).
-For styling of the preview, the preview element will have the id `preview` and the className will be set to the mimetype of the file being edited with any slash replaced by dashes.
+Migration prerequisites for this repository:
-e.g. when editing a markdown file the preview element can be styled using the `#preview.text-markdown` css query.
+- **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 Text Editor
+
+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
+- **Test framework:** PHPUnit
+- **CI system:** GitHub Actions
+
+## Architecture & Key Paths
+
+- `appinfo/` -- App metadata and registration
+- `controller/` -- PHP controllers
+- `js/` -- Frontend JavaScript (Ace editor integration)
+- `css/` -- Stylesheets
+- `l10n/` -- Translations
+- `tests/` -- PHPUnit tests
+- `CONTRIBUTING.md` -- Contribution guidelines
+- `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-php-unit
+
+# Lint
+make test-php-style
+```
+
+## 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
