-//! Instructions:
-//!
-//! - Source the ROS2 setup files (e.g. `source /opt/ros/iron/setup.bash`)
-//! - Run `ros2 run turtlesim turtlesim_node`
-//! - Open a second terminal and source the ROS2 setup files again.
-//! - Run this example to move the turtle in random directions: `cargo run --example random_turtle`
