 1- Setup Semantic Segmentation Inference Node
------------------------------------------------
+---------------------------------------------
 
 The semantic segmentation node performs real-time inference on camera images using an ONNX model. It subscribes to camera images, runs inference, and publishes segmentation masks, confidence maps, and label information.
 To run the semantic segmentation node, you need to install the dependencies from the `requirements.txt <https://github.com/ros-navigation/navigation2_tutorials/blob/master/nav2_semantic_segmentation_demo/semantic_segmentation_node/requirements.txt>`_ file in the semantic_segmentation_node package:

 The tutorial provides a pre-configured `nav2_params.yaml <https://github.com/ros-navigation/navigation2_tutorials/blob/master/nav2_semantic_segmentation_demo/semantic_segmentation_sim/config/nav2_params.yaml>`_ file in the semantic_segmentation_sim package. You can use it to configure the Nav2 costmaps for your own application.
 
 3- Run everything together
-----------------------------
+--------------------------
 
 The tutorial provides a complete launch file that launches the simulation, the semantic segmentation node, and the Nav2 navigation stack. To run it, simply launch the `segmentation_simulation_launch.py <https://github.com/ros-navigation/navigation2_tutorials/blob/master/nav2_semantic_segmentation_demo/semantic_segmentation_sim/launch/segmentation_simulation_launch.py>`_ file:
