+    Gazebo does not have an arm64 build target. If using a companion computer with arm64 architecture, run this command instead of the `rosdep install` command above:
 
-    ```rosdep install -i --from-path ./ -y --ignore-src --skip-keys="gazebo_dev gazebo_plugins gazebo_ros gazebo" -r```

-    Also note that Gazebo is currently used only in the ```rosflight_sim``` package, in the ```rosflight_ros_pkgs``` directory. A CMakeLists command in this package will skip compilation of ```rosflight_sim``` if arm64 architecture is detected. If using a companion computer that uses arm64 architecture and you want rosflight_sim, you will need to remove the CMakeLists command and Gazebo.
