The description provides an overview over the question, usually defining the context. This makes the question shorter and allows it to be scanned quicker.

For simple questions, where the context is clear, the description is often overkill. Sometimes even the Short Description is more than is needed. But for complex environments, it may come handy. Check if the context may be transcluded from a Module document.

Formulate the question from the reader's view, in the context defined in the Description. Try to make it short and precise. Readers scanning the questions should find it easy to locate the relevant documents.

Make the answer short and precise. Maybe add links for readers to find more information on this topic quickly.

Since questions and answers are usually aggregated on pages to form lists, it may make sense to add links to this section in addition to links in the References and Resources sections.
