+## 🪟 Windows Setup Guide
+
+If you're using Windows, follow these additional steps to set up the required dependencies:
+
+### 1. Install Tesseract OCR
+1. Download the Tesseract installer from [UB Mannheim's GitHub repository](https://github.com/UB-Mannheim/tesseract/wiki)
+2. Choose the appropriate installer:
+   - For 64-bit Windows: `tesseract-ocr-w64-setup-xxx.exe`
+   - For 32-bit Windows: `tesseract-ocr-w32-setup-xxx.exe`
+3. During installation:
+   - Choose the default installation path (`C:\Program Files\Tesseract-OCR`)
+   - **Important**: Check the box for "Add to system PATH"
+   - Complete the installation
+
+### 2. Set Up Environment Variables
+1. Create a `.env` file in your project's root directory (same level as `pyproject.toml`)
+2. Add the following lines to your `.env` file:
+```
+TESSERACT_PATH="C:\Program Files\Tesseract-OCR\tesseract.exe"
+OPENAI_API_KEY="your-openai-api-key-here"
+```
+3. Replace `your-openai-api-key-here` with your actual OpenAI API key
+
+### 3. Verify Installation
+1. Open a new PowerShell window (the PATH changes require a new terminal session)
+2. Verify Tesseract installation:
+```powershell
+where.exe tesseract
+```
+3. You should see the path to your Tesseract executable
+
+### 4. Running Examples
+1. Make sure you're in your project's virtual environment:
+```powershell
+.\.venv\Scripts\Activate.ps1
+```
+2. If you get a security error about running scripts, run:
+```powershell
+Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope Process
+```
+3. Run your example script:
+```powershell
+python examples/extractor_basic.py
+```
+
+### Common Issues and Solutions
+- **Tesseract not found**: Make sure Tesseract is installed and added to PATH. Try restarting your terminal.
+- **Environment variables not loading**: Ensure your `.env` file is in the correct location and has the correct format.
+- **Script execution policy**: If you get a security error, use the `Set-ExecutionPolicy` command shown above.
+- **Virtual environment issues**: Make sure you're using the correct Python version (3.9+) and have activated the virtual environment.
