Introduce the concept and provide a concise answer to the question "What is this?" and in some cases "Why do I care about this?" If the concept is unfamiliar, you can start with a brief definition. Avoid using the short description to lead in or build up to a topic. The short description paragraph should contain the main point of the conceptual topic. The concept short description should clearly apply to a concept. Avoid turning the concept topic into a task. Do not simply repeat the title
