 ## Environment information
 This setup was implemented and tested with the following conditions:
-- Ubuntu 20.04
-- ROS2 Galactic
+- Ubuntu 20.04 | ROS2 Galactic
+- Ubuntu 22.04 (Jammy) | ROS2 Iron
 
 Since it does not really use Galactic-specific code, it should also work with ROS2 Dashing/Foxy and Humble.
 It does **NOT** work on Linux 16.04 in combination with ROS2 Ardent.
