+# Contributing
+
+Thanks for helping improve simplenotes. The goal of this project is a simple, local-first, open-source notes app with a strong mobile ink foundation.
+
+Small, focused contributions are welcome: bug reports, reproducible crashes, device-specific PDF import/export issues, documentation fixes, UI polish, and careful fixes to local storage or native integration all help.
+
+## Development Setup
+
+```sh
+npm ci --legacy-peer-deps
+npm run typecheck
+```
+
+Run the app with an Expo dev client:
+
+```sh
+npx expo run:ios
+npx expo run:android
+```
+
+Expo Go is not supported because the app depends on native code from `@mathnotes/mobile-ink`.
+
+## Pull Request Expectations
+
+- Keep changes focused and easy to review.
+- Run `npm run typecheck` before opening a PR.
+- Rebuild and manually test on a real device when touching native code, PDF import/export, file handling, or Mobile Ink integration.
+- Do not include private notes, imported PDFs, screenshots with personal information, credentials, signing files, generated build outputs, or local caches.
+- Preserve the local-first privacy model. Do not add analytics, tracking, account systems, sync services, or network calls without a clear public discussion first.
+
+## App And Engine Boundaries
+
+Use this repo for the simplenotes app: library UX, note storage, PDF import/export behavior, app chrome, and platform submission work.
+
+Use [`mathnotes-app/mobile-ink`](https://github.com/mathnotes-app/mobile-ink) for reusable ink-engine bugs, canvas primitives, native rendering, selection behavior, stroke serialization, and engine-level PDF/page handling.
+
+If a bug crosses both repos, open the app issue here and link the Mobile Ink issue or PR.
