+# Contributing to Docling Studio
+
+Thank you for your interest in contributing to Docling Studio! This guide will help you get started.
+
+## Getting Started
+
+1. **Fork** the repository on GitHub
+2. **Clone** your fork locally:
+   ```bash
+   git clone https://github.com/<your-username>/Docling-Studio.git
+   cd Docling-Studio
+   ```
+3. **Create a branch** for your work:
+   ```bash
+   git checkout -b feature/my-feature
+   ```
+
+## Development Setup
+
+### Backend (Python 3.12+)
+
+```bash
+cd document-parser
+python -m venv .venv && source .venv/bin/activate
+pip install -r requirements.txt
+pip install ruff pytest pytest-asyncio httpx  # dev tools
+uvicorn main:app --reload --port 8000
+```
+
+### Frontend (Node 20+)
+
+```bash
+cd frontend
+npm install
+npm run dev
+```
+
+## Code Quality
+
+### Backend — Ruff
+
+We use [Ruff](https://docs.astral.sh/ruff/) for linting and formatting Python code.
+
+```bash
+cd document-parser
+ruff check .          # lint
+ruff check . --fix    # lint with auto-fix
+ruff format .         # format
+```
+
+### Frontend — ESLint + Prettier
+
+```bash
+cd frontend
+npx eslint src/       # lint
+npx prettier --check src/  # check formatting
+npx prettier --write src/  # auto-format
+```
+
+## Running Tests
+
+```bash
+# Backend (99 tests)
+cd document-parser
+pytest tests/ -v
+
+# Frontend (87 tests)
+cd frontend
+npm run test:run
+```
+
+All tests must pass before submitting a PR.
+
+## Submitting Changes
+
+1. **Commit** with clear, descriptive messages
+2. **Push** your branch to your fork
+3. Open a **Pull Request** against `main`
+4. Describe **what** changed and **why** in the PR description
+5. Ensure CI passes (tests + build)
+
+## Pull Request Guidelines
+
+- Keep PRs focused — one feature or fix per PR
+- Add tests for new functionality
+- Update documentation if behavior changes
+- Follow existing code style and conventions
+
+## Reporting Issues
+
+- Use GitHub Issues to report bugs or request features
+- Include steps to reproduce for bugs
+- Mention your OS, Python/Node version, and Docker version if relevant
+
