(Beginner) Just learning about the topic. Starting on a first project but needs supervision/direction through each of the steps. (Intermediate) Has completed a few significant projects and is generally capable of working unsupervised. Not quite capable of architecting complex solutions but able to modify a project to achieve an objective. (Advanced) Able to plan and execute a novel solution independently.

(Tutorials) are step-by-step narratives meant to walk a user through a project/task for the sake of familiarizing them with the concept and workflow, and accomplishing something arbitrary quickly and easily, but not necessarily comprehensively. (Guides) are step-by-step instructions that answer specific "How do I..." questions without the cushion of context that tutorials provide, but are more comprehensive and applicable to real-world problems. (Quickstarts) are a specific set of instructions combined from various topics that gives you only exactly what you need to start. E.g. a student-geared quickstart might include basic Linux commands, ROS 2 cli tools, and how to use pub-sub. (Concept overviews) are a high-level explanation or "big picture" of a topic.

List topics in priority order (highest priority first), comma separated. Try to be as general as possible (e.g. "more beginner content", "navigation", "RViz"). Requests for exact topics can be submitted as issues to github.com/ros2/ros2_documentation
