+# Contributing
+
+Thanks for contributing to WebUI Zig.
+
+## Development Setup
+
+- Zig `0.15.2+` (see `build.zig.zon`)
+- Linux, macOS, or Windows
+
+Core commands:
+
+```bash
+zig build
+zig build test
+zig build examples
+zig build parity-local
+```
+
+## Branching and PRs
+
+- Create focused PRs with one clear goal.
+- Include tests for behavior changes.
+- Keep public API changes documented in `MIGRATION.md` and `DOCUMENTATION.md`.
+- Do not commit binaries or cache outputs.
+
+## Code Quality Rules
+
+- Run `zig fmt` on changed Zig files.
+- Keep active runtime pure Zig.
+- Do not add `@cImport`, `translate-c`, or active C/C++ runtime source paths.
+- Prefer explicit, deterministic behavior over implicit fallbacks.
+
+Static guards are enforced by build steps; keep them green.
+
+## Testing Expectations
+
+Before opening a PR, run:
+
+```bash
+zig build test
+zig build examples
+zig build parity-local
+```
+
+If your change affects launch/runtime behavior, also test at least one real GUI run:
+
+```bash
+zig build run -Dexample=minimal -Drun-mode=webview,browser,web-url
+```
+
+## Commit Guidance
+
+- Use clear commit messages describing behavior changes.
+- Mention platform-specific impact (Linux/macOS/Windows) when relevant.
+- If a breaking API change is intentional, call it out explicitly.
+
+## Reporting Regressions
+
+Include:
+
+- exact command used
+- OS + Zig version
+- expected behavior vs actual behavior
+- logs or stack trace
