+## Code Standards
+
+- **TypeScript**: All code should be written in TypeScript with proper type definitions
+- **Linting**: Run `yarn lint` before committing. Use `yarn fix` to auto-fix formatting issues
+- **Testing**: Add tests for new features and bug fixes
+- **Documentation**: Update relevant documentation (README.md, MANIFEST.md, etc.) when adding or changing functionality
+
+## Commit Signing
+
+**All commits must be signed.** This helps verify the authenticity of contributions.
+
+To set up commit signing, see [GitHub's documentation on commit signature verification](https://docs.github.com/en/authentication/managing-commit-signature-verification).
