+# Contributing to agent-browser
+
+Thanks for your interest in contributing! This guide covers everything you need to get started.
+
+## Prerequisites
+
+- **Node.js** >= 20
+- **pnpm** (install via `corepack enable` or `npm i -g pnpm`)
+- **Rust** (optional, only needed for native CLI builds — install via [rustup](https://rustup.rs))
+
+## Dev Environment Setup
+
+1. **Fork and clone:**
+
+```bash
+git clone https://github.com/<your-username>/agent-browser.git
+cd agent-browser
+```
+
+2. **Install dependencies:**
+
+```bash
+pnpm install
+```
+
+3. **Install Chromium (for running tests):**
+
+```bash
+npx agent-browser install
+```
+
+4. **Verify everything works:**
+
+```bash
+pnpm test
+pnpm typecheck
+```
+
+## Project Structure
+
+```
+agent-browser/
+├── src/              # TypeScript source (daemon, actions, protocol, etc.)
+├── cli/              # Rust CLI (optional native binary)
+├── dist/             # Compiled output (gitignored)
+├── scripts/          # Build & version sync helpers
+├── docker/           # Cross-compilation Docker configs
+├── test/             # Test utilities
+├── bin/              # Pre-built native binaries
+└── docs/             # Additional documentation
+```
+
+## Coding Style
+
+- **TypeScript** with strict mode (`"strict": true` in tsconfig)
+- **Formatting:** Prettier — run `pnpm format` before committing
+- **Lint check:** `pnpm format:check` ensures your code matches the style
+- **Naming:**
+  - `camelCase` for variables and functions
+  - `PascalCase` for classes and types
+  - `kebab-case` for filenames
+- **Imports:** Use `import` (ESM), not `require`
+
+## Running Tests
+
+```bash
+pnpm test           # Run all tests once
+pnpm test:watch     # Run tests in watch mode
+pnpm typecheck      # TypeScript type checking
+```
+
+Tests use [Vitest](https://vitest.dev/). Test files live alongside source files as `*.test.ts`.
+
+## Making Changes
+
+1. **Create a branch:**
+
+```bash
+git checkout -b feat/my-feature
+# or fix/my-bug
+```
+
+2. **Make your changes** following the coding style above.
+
+3. **Run checks before committing:**
+
+```bash
+pnpm format         # Auto-format
+pnpm typecheck      # Verify types
+pnpm test           # Run tests
+```
+
+4. **Commit with a clear message:**
+
+```bash
+git commit -m "feat: add support for X"
+# or "fix: resolve issue with Y"
+```
+
+We follow [Conventional Commits](https://www.conventionalcommits.org/) (`feat:`, `fix:`, `docs:`, `chore:`, etc.).
+
+## Submitting a PR
+
+1. Push your branch to your fork.
+2. Open a Pull Request against `main`.
+3. Fill in the PR description — explain **what** and **why**.
+4. Ensure CI passes (lint, typecheck, tests).
+5. Wait for review. Be responsive to feedback.
+
+## Adding CLI Commands
+
+If you're adding a new subcommand:
+
+1. Add the action handler in `src/actions.ts`
+2. Register it in the Rust CLI under `cli/src/main.rs` (if targeting native)
+3. Add tests in `src/actions.test.ts`
+4. Update `README.md` with usage examples
+
+## Reporting Issues

+- Include: OS, Node.js version, steps to reproduce, expected vs actual behavior
+- For security issues, email security@dextonhub.com instead of opening a public issue
