+## Usage Examples
+
+Check the `examples/` directory for ready-to-run scripts demonstrating core features:
+
+*   **`examples/01_simple_route.py`**: Basic single-net routing with visualization.
+*   **`examples/02_congestion_resolution.py`**: Multi-net routing resolving bottlenecks using Negotiated Congestion.
+*   **`examples/03_locked_paths.py`**: Incremental workflow using `lock_net()` to route around previously fixed paths.
