Here's some resources I've come across: * [Understanding CLI tools](https://docs.ros.org/en/humble/Tutorials.html) * [ROS2 Humble Tutorial](https://docs.ros.org/en/humble/Tutorials.html) * [ROS2 Publisher / Subscriber Walkthrough](https://docs.ros.org/en/humble/Tutorials/Beginner-Client-Libraries/Writing-A-Simple-Py-Publisher-And-Subscriber.html)
