 ## Contribute
 Checkout the organization [CONTRIBUTING.md](https://github.com/react-dropzone/.github/blob/main/CONTRIBUTING.md).
 
+### Development
+
+Development requires [Node.js](https://nodejs.org) >= 20. Install the dependencies with:
+```bash
+npm install
+```
+
+The project is built with [tsdown](https://tsdown.dev) (Rolldown), type-checked with [TypeScript](https://www.typescriptlang.org), tested with [Vitest](https://vitest.dev) and linted/formatted with [oxlint](https://oxc.rs) and [oxfmt](https://oxc.rs).
+
+| Command | Description |
+| --- | --- |
+| `npm test` | Run the test suite in watch mode. |
+| `npm run test:cov` | Run the tests once with coverage (runs type-check, lint and format check first). |
+| `npm run type-check` | Type-check the sources without emitting. |
+| `npm run lint` | Lint the sources (oxlint). |
+| `npm run lint:fix` | Apply safe lint fixes. |
+| `npm run lint:type-aware` | Type-aware lint via tsgolint (alpha). |
+| `npm run format` | Format the sources (oxfmt). |
+| `npm run format:check` | Check formatting without writing. |
+| `npm run build` | Build the outputs into `dist/`. |
+| `npm run dev` | Build in watch mode. |
+
+The build emits into `dist/`:
+- `dist/index.js` — ES module
+- `dist/index.cjs` — CommonJS module
+- `dist/index.d.ts` — TypeScript declarations
