+# Contributing
+
+Thanks for contributing to the Bright Data CLI. This is a TypeScript project that
+compiles to a Node CLI (`brightdata` / `bdata`).
+
+## Prerequisites
+
+- **Node.js 20+** (CI builds on Node 24 — matching the current LTS avoids surprises).
+- **pnpm** — pinned via the `packageManager` field. Let Corepack provide it:
+  ```bash
+  corepack enable
+  ```
+
+## Setup
+
+```bash
+pnpm install
+pnpm run build           # compile src/ → dist/
+node dist/index.js --help   # run your build (or: pnpm start)
+```
+
+## Common commands
+
+| Command | What it does |
+|---|---|
+| `pnpm run build` | Compile TypeScript to `dist/` |
+| `pnpm run dev` | Compile in watch mode |
+| `pnpm run type-check` | Type-check only, no emit (`tsc --noEmit`) |
+| `pnpm test` | Run the test suite once (Vitest) |
+| `pnpm run test:watch` | Run tests in watch mode |
+| `pnpm start` | Run the built CLI (`node dist/index.js`) |
+| `pnpm run clean` | Remove `dist/` |
+
+## Project layout
+
+```
+src/
+  index.ts        # entry point / bin (wires up all commands)
+  commands/       # one file per CLI command (scrape, search, browser, …)
+  browser/        # local browser-daemon: lifecycle, ipc, connection, interaction
+  utils/          # shared helpers (client, config, auth, output, polling, …)
+  types/          # shared type definitions
+  __tests__/      # Vitest tests, mirroring the src/ layout
+install.sh        # curl | sh installer
+```
+
+## Testing
+
+- Tests live in `src/__tests__/**/*.test.ts`, mirroring the source tree, and run on
+  **Vitest** (`pnpm test`). Add a test alongside any behavior change.
+- **CI does not run the suite** — `release.yml` only builds and publishes on release
+  tags. Please run `pnpm run type-check` **and** `pnpm test` locally before opening a
+  PR; that's the only safety net.
+- A few browser/daemon tests depend on a real browser environment and may not pass on
+  every machine — note in your PR if a failure is pre-existing/environmental rather
+  than caused by your change.
+
+## Code style
+
+Match the surrounding file. The house style is:
+
+- **`snake_case`** for functions and variables (`handle_scrape`, `ensure_authenticated`).
+- **Allman braces** — opening brace on its own line for blocks:
+  ```ts
+  if (!zone)
+  {
+      fail('...');
+      return;
+  }
+  ```
+- 4-space indentation, single quotes, arrow functions assigned to `const`, and
+  **named exports** grouped at the bottom of the file.
+- Keep diffs minimal and consistent with the file you're editing.
+
+## Commits & pull requests
+
+- Use **Conventional Commits**: `feat(scraper): …`, `fix(browser): …`,
+  `docs(readme): …`, `refactor: …`, `chore: …`.
+- Branch off `main` and open your PR against `main`.
+- Before pushing: `pnpm run type-check && pnpm test && pnpm run build` should all pass.
+- Keep PRs focused; describe what changed and how you verified it.
+
+## Releases
+
+Maintainers cut releases by bumping the version and pushing a `v*` tag, which triggers
+the `release.yml` workflow to build and `npm publish`.
