-Using the docker compose file automatically builds the workspace and allows you to choose between running on the CPU or GPU for applications like Rviz2 and Gazebo:
-
-```bash
-  # Run on CPU
-$ docker compose run --rm --name rover-ros2-container cpu
-  # Run on GPU (NVidia only)
-$ docker compose run --rm --name rover-ros2-container gpu
