 # Compile from source
 
 Note that `gz_ros2_control` depends on the version of Gazebo that is
 provided by the Gazebo Vendor packages [`gz_plugin_vendor`](https://github.com/gazebo-release/gz_plugin_vendor) and [`gz_sim_vendor`](https://github.com/gazebo-release/gz_sim_vendor).
 Currently, for ROS 2 Jazzy and Rolling, the Gazebo version is Harmonic.
