You can find the rest of his tutorials here: Josh Newman's ROS2 Tutorials
caution
Your computer should be a Linux computer running Ubuntu. The specific version of Ubuntu will match up with the version of ROS2 you are installing. For example, if you are installing ROS2 Foxy Fitzroy, you will need to be running Ubuntu 20.04.
note
ROS2 is available on other operating systems such as Windows and MacOS but the installation process is different. For Windows you can use WSL2 to install ROS2.
