You're reading the documentation for a version of ROS 2 that has reached its EOL (end-of-life), and is no longer officially supported. If you want up-to-date information, please have a look at Iron.
The tutorials are a collection of step-by-step instructions meant to steadily build skills in ROS 2.
The best way to approach the tutorials is to walk through them for the first time in order, as they build off of each other and are not meant to be comprehensive documentation.
For quick solutions to more specific questions, see the Guides.
