 ### Environment Variables
-- `PORT`: Server port (default: 7860)
+
+The server automatically loads environment variables from a `.env` file in the project root. Create a `.env` file with:
+
+- `TURSO_AUTH_TOKEN`: Authentication token for Turso database (required)
+- `TURSO_DATABASE_URL`: Database URL for Turso (libSQL) connection (required)
+- `PORT`: Server port (default: 7860, optional)
+
+**Note**: The `.env` file is automatically ignored by git to keep your credentials secure. You can also set these as system environment variables if preferred.
