You're reading the documentation for an older, but still supported, version of ROS 2. For information on the latest version, please have a look at Humble.
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 How-to Guides.
