 # Introduction
-Here are the ROS packages of Unitree robots, namely Laikago, Aliengo and A1. You can load robots and joint controllers in Gazebo. And we also offered a basic standing controller, a position and pose publisher and a tool to generate external force. Besides of these simulation functions, you can also control your real robots in ROS by the `unitree_legged_real`.
+Here are the ROS packages of Unitree robots, namely Laikago, Aliengo and A1. You can load robots and joint controllers in Gazebo, so you can do low-level control on the robot joints. Please watch out that the Gazebo simulation cannot do high-level control, namely walking. Besides of these simulation functions, you can also control your real robots in ROS by the `unitree_legged_real`. For real robots, you can do high-level and low-level control by our ROS packages.
 
 ## Packages:
 Robot description: `a1_description`, `aliengo_description`, `laikago_description`
