 The SDK uses environment variables for configuration. You can set these up in two ways:
 
 1. Using a `.env` file (recommended):
-   .. code-block:: bash
-
-      # Create a .env file in your project root
-      BT_API_KEY="your-api-key"
-      BT_PANEL_HOST="http://localhost:8888"
-      DEBUG=False

-      VERIFY_SSL=False

 > 注意：`.env` 文件应该添加到 `.gitignore` 中，以保护您的 API 密钥安全。
