            1. **Get a Free API Key:**
               - Visit: https://fred.stlouisfed.org/docs/api/api_key.html
               - Sign up for a free account
               - Generate your API key
            
            2. **Set Environment Variable:**
               ```bash
               export FRED_API_KEY='your-api-key-here'
               ```
            
            3. **Or Create .env File:**
               Create a `.env` file in the project root with:
               ```
               FRED_API_KEY=your-api-key-here
               ```
            
            4. **Restart the Application:**
               The app will automatically detect the API key and switch to real data.
