+
+## Reporting Bugs
+
+1. Check if the issue already exists in [Issues](https://github.com/wcmendes/MdBundle-for-Zotero/issues)
+2. Open a new issue with:
+   - Your Zotero version (e.g., 9.0.6)

+   - Steps to reproduce the bug
+   - Expected vs actual behavior

+
+## Suggesting Features
+
+Open an issue with the `enhancement` label describing your use case and proposed feature.
+
+## Translations
+
+We welcome translations! To add a new language:
+
+1. Copy `src/locale/en-US/mdbundle.ftl` to `src/locale/<your-locale>/mdbundle.ftl`
+2. Translate all values (keep the keys unchanged)
+3. Add your locale to the `supported` array in `src/mdbundle.js` → `loadStrings()`
+4. Submit a Pull Request
+
+## Code Contributions
+
+1. Fork the repository
+2. Create a feature branch (`git checkout -b feature/my-feature`)
+3. Make your changes in `src/`
+4. Test by building the XPI: `cd src && zip -r ../mdbundle.xpi .`
+5. Install and test in Zotero
+6. Commit and push
+7. Open a Pull Request
+
+## Building
+
+```bash
+cd src
+zip -r ../mdbundle.xpi .
+```
+
+Then install the XPI in Zotero: Tools → Add-ons → ⚙️ → Install Add-on From File.
+
+## Code Style
+
+- Use tabs for indentation
+- Use `async/await` for asynchronous code
+- All user-facing strings must use the `this.s('key')` i18n system
+- Add corresponding entries to all locale `.ftl` files (at minimum `en-US`)
