+# Puaros
+
+A TypeScript monorepo for Puaros project.
+
+## Prerequisites
+
+- Node.js 22.18.0 (use `nvm use` to automatically switch to the correct version)
+- pnpm (package manager)
+
+## Getting Started
+
+### Installation
+
+```bash
+# Install dependencies
+pnpm install
+```
+
+### Development
+
+```bash
+# Build all packages
+pnpm build:all
+
+# Clean all build outputs
+pnpm clean:all
+
+# Run CLI in development mode
+pnpm dev:cli
+```
+
+### Testing
+
+```bash
+# Run all tests across packages
+pnpm test
+
+# Run tests with coverage (80% threshold required)
+cd packages/core && pnpm test:coverage
+
+# Run tests with UI
+cd packages/core && pnpm test:ui
+
+# Run tests once (no watch mode)
+cd packages/core && pnpm test:run
+```
+
+The project uses Vitest for testing with coverage thresholds set to 80% for all metrics (lines, functions, branches, statements).
+
+### Code Quality
+
+```bash
+# Format all code (IMPORTANT: uses 4-space indentation)
+pnpm format
+
+# Lint and auto-fix
+pnpm lint
+
+# Check linting without fixing
+pnpm eslint "packages/**/*.ts"
+```

+
+## Code Style
+
+This project follows strict TypeScript and code quality standards:
+
+- **Indentation:** 4 spaces (enforced by Prettier)
+- **Line Length:** 100 characters maximum
+- **Quotes:** Single quotes
+- **Semicolons:** Always required
+- **TypeScript:** Strict type checking enabled
+
+### Key Rules
+
+- No `any` type without explicit reasoning
+- Explicit function return types required
+- No floating promises - always await or handle
+- Use `const` for non-reassigned variables
+- Always use `===` instead of `==`
+- Curly braces required for all control structures
+- No `console.log` (use `console.warn`/`console.error` or proper logger)
+
+See [LINTING.md](./LINTING.md) for detailed code style guidelines.
+
+## Monorepo Structure
+
+This project uses pnpm workspaces for managing multiple packages:
+
+- **Packages** are located in `packages/*`
+- All packages share TypeScript configuration via `tsconfig.base.json`
+- Dependencies are hoisted and shared when possible
+
+### Adding a New Package
+
+1. Create `packages/your-package/` directory
+2. Add `package.json` with name `@puaros/your-package`
+3. Create `tsconfig.json` extending `../../tsconfig.base.json`
+4. The package will be auto-discovered via workspace configuration
+
+## Dependencies
+
+Core package uses:
+
+- `simple-git` - Git operations
+- `tree-sitter`, `tree-sitter-javascript`, `tree-sitter-typescript` - Code parsing
+- `uuid` - UUID generation
+
+Development tools:
+
+- Vitest - Testing framework
+- ESLint + TypeScript ESLint - Strict type checking and linting
+- Prettier - Code formatting
+
+## Contributing
+
+1. Ensure Node.js version matches `.nvmrc` (22.18.0)
+2. Run `pnpm format` before committing to ensure consistent formatting
+3. All tests must pass with 80% coverage
+4. Fix all ESLint warnings - they indicate real type safety issues
