+# Contributing to NomiFun
+
+NomiFun is a Rust + Tauri + React monorepo. This file is the open-source entry
+point for contributors; the detailed engineering docs live under `docs/`.
+
+## Start Here
+
+- [Project structure](docs/contributing/project-structure.md)
+- [Development workflow](docs/contributing/development.md)
+- [Building and packaging](docs/contributing/building-and-packaging.md)
+- [Architecture overview](docs/architecture/overview.md)
+- [Code of conduct](CODE_OF_CONDUCT.md)
+- [Security policy](SECURITY.md)
+
+## Local Setup
+
+```bash
+bun install
+bun run dev
+```
+
+Use `bun run dev:web` for the browser-only development loop and
+`bun run serve:web` to run the headless server after building the SPA.
+
+## Checks
+
+Run the narrowest check that covers your change:
+
+```bash
+bun run help --check
+bun run typecheck
+bun run check
+cargo test
+```
+
+For UI-only work, prefer package-relative Bun commands from `ui/` or
+`bun run --filter=./ui ...` from the repo root. For Rust-only work, use the
+specific crate or test target where possible before running the full suite.
+
+## Documentation Changes
+
+- Keep current docs under `docs/getting-started`, `docs/guides`,
+  `docs/architecture`, `docs/reference`, and `docs/contributing`.
+- Design and audit history is not kept in the repo; consult git history for past
+  decisions rather than re-adding dated design docs.
+- Do not document redirected legacy routes as primary navigation.
+- Keep English and Simplified Chinese siblings in sync when both exist.
+
+## Pull Request Expectations
+
+- Keep changes scoped and explain user-visible behavior.
+- Include screenshots for visible UI changes when practical.
+- Update docs and screenshot manifest rows when routes, setup steps, or
+  feature names change.
+- Do not commit local data directories, generated build output, credentials, or
+  machine-specific configuration.
+- Do not add third-party assets or vendored skills unless their redistribution
+  license is compatible with this repository.
+
+## Releases
+
+Maintainer release steps live in [RELEASING.md](RELEASING.md). User-facing
+changes should be summarized in [CHANGELOG.md](CHANGELOG.md).
