+# Installation and Setup Guide
+
+## ✅ Installation Complete!
+
+Your PyDIPLink package has been successfully installed and tested.
+
+## What Was Done
+
+### 1. Virtual Environment Setup
+```bash
+# A fresh virtual environment was created
+python3 -m venv venv
+
+# Activate it (run this command every time you work on the project)
+source venv/bin/activate  # On Linux/Mac
+# OR
+venv\Scripts\activate  # On Windows
+```
+
+### 2. Package Installation
+```bash
+# Installed in editable mode with dev dependencies
+pip install -e ".[dev]"
+```
+
+### 3. Test Results
+✅ **14/14 tests passed!**
+- UART handler: 6/6 tests ✓
+- Image transfer: 8/8 tests ✓
+- Code coverage: 43% (core functionality tested)
+
+## Quick Start
+
+### Activate Virtual Environment (IMPORTANT!)
+Every time you open a new terminal, activate the environment:
+```bash
+cd /home/odurgut/book/PyDIPLink
+source venv/bin/activate
+```
+
+You should see `(venv)` in your prompt:
+```
+(venv) odurgut@odurgut:~/book/PyDIPLink$
+```
+
+### Run the CLI
+```bash
+# Show help
+pydiplink --help
+
+# Run with custom port
+pydiplink --port /dev/ttyUSB0 --baud 500000
+```
+
+### Use in Python
+```python
+import pydiplink
+
+print(pydiplink.__version__)  # 0.2.0
+
+# Import functions
+from pydiplink import send_image_data, IMAGE_FORMAT_RGB888
+```
+
+## Development Commands
+
+### Run Tests
+```bash
+pytest                    # Run all tests
+pytest -v                # Verbose output
+pytest --cov=pydiplink   # With coverage report
+```
+
+### Code Quality
+```bash
+# Format code
+black pydiplink
+
+# Check imports
+isort pydiplink
+
+# Lint
+flake8 pydiplink
+
+# Type check
+mypy pydiplink
+```
+
+### Pre-commit Hooks
+```bash
+# Install hooks (one-time)
+pre-commit install
+
+# Run manually
+pre-commit run --all-files
+```
+
+## Troubleshooting
+
+### "externally-managed-environment" Error
+**Problem:** Trying to install without activating venv
+
+**Solution:** Always activate the virtual environment first:
+```bash
+source venv/bin/activate
+```
+
+### ImportError
+**Problem:** Package not found
+
+**Solution:** Make sure you're in the activated venv and reinstall:
+```bash
+source venv/bin/activate
+pip install -e ".[dev]"
+```
+
+### Serial Port Permission Denied
+**Problem:** Can't access `/dev/ttyUSB0`
+
+**Solution:** Add your user to dialout group (Linux):
+```bash
+sudo usermod -a -G dialout $USER
+# Log out and log back in
+```
+
+## Next Steps
+
+1. **Test with Hardware**: Connect your STM32 and try the examples
+   ```bash
+   cd examples
+   python basic_image_transfer.py
+   ```
+
+2. **Read Documentation**: Check the comprehensive docs
+   - [README.md](README.md) - Overview and quick start
+   - [docs/API.md](docs/API.md) - Complete API reference
+   - [CONTRIBUTING.md](CONTRIBUTING.md) - Development guidelines
+
+3. **Set Up Git**: Prepare for version control
+   ```bash
+   git add .
+   git commit -m "Complete professional refactoring v0.2.0"
+   git tag v0.2.0
+   ```
+
+4. **Publish to PyPI** (when ready):
+   ```bash
+   python -m build
+   twine upload dist/*
+   ```
