Help and documentation assist users in understanding and effectively operating a system. They serve as supplementary resources when functions are not self-explanatory or issues arise. Good help is easy to find, clearly written, and task-oriented. It can take the form of tooltips, FAQs, step-by-step guides, or detailed user manuals. The goal is to reduce uncertainty, prevent errors, and support user independence. Help and documentation are essential components of user-centered design and contribute significantly to a positive user experience.
