+# Contributing to draw
+
+Thanks for your interest. draw is a small project; contributions that keep it small are welcome.
+
+## Dev setup
+
+```bash
+bin/setup    # install toolchains + wasm-pack + Python deps
+bin/build    # build everything (Rust + Python + WASM)
+bin/install  # install the CLI
+```
+
+macOS or Linux. The desktop app depends on system GTK/WebKit on Linux; on macOS it uses the built-in WebView.
+
+## Workflow
+
+```bash
+bin/check    # fmt, clippy, tests — Rust and Python. Run before you push.
+bin/format   # apply formatting
+bin/test     # tests only
+```
+
+CI runs `bin/check` on every PR. Narrower scripts (`bin/check-rs`, `bin/check-py`) exist for iteration but the full `bin/check` is the gate.
+
+## Running it
+
+```bash
+draw --webapp    # web UI at http://localhost:1213
+draw --app       # desktop window
+```
+
+## Layout
+
+See `AGENTS.md` for the crate map. Short version:
+
+- `crates/draw-core`: document model, serialization, SVG/PNG export, renderer
+- `crates/draw-cli`: the `draw` binary
+- `crates/draw-webapp`: Axum server + embedded vanilla-JS frontend
+- `crates/draw-app`: desktop webview wrapper
+- `crates/draw-wasm`: renderer compiled to WASM for the browser
+- `crates/draw-py`: PyO3 Python bindings
+- `py/dkdc_draw`: Python package + type stubs
+
+## PRs
+
+- One logical change per PR. Small and focused beats big and sweeping.
+- Commit style: [Conventional Commits](https://www.conventionalcommits.org/) (`feat:`, `fix:`, `refactor:`, `docs:`, `chore:`, `ci:`).
+- Keep `bin/check` green.
+- New features should come with tests. Bug fixes should come with a regression test when practical.
+- User-visible changes warrant a line in `README.md` (feature list or keyboard table) or `CHANGELOG.md`.
+
+## Reporting bugs
+
+Open an issue at https://github.com/dkdc-io/draw/issues. Include:
+
+- What you did
+- What you expected
+- What actually happened
+- `draw --version`, OS, and whether you hit it in `--webapp` or `--app`
+
+A minimal `.draw.json` reproducing the bug is gold.
+
