+## Current Status of ROS 1 and ROS 2 Packages
+The current CARMA Platform system operates as a hybrid of ROS 1 Noetic and ROS 2 Foxy components. While nearly all components have been upgraded to ROS 2 Foxy, a small amount of ROS 1 Noetic content still exists within the system, including some packages in this repository. For more information, please see the relevant documentation in the [carma-config](https://github.com/usdot-fhwa-stol/carma-config?tab=readme-ov-file#current-status-of-hybrid-ros-1ros-2-system) repository.
