Articles can be created with just a name (display title), text (details) and page-title tag (for search engines). It is also suggested to use keywords; as well as populating the meta-keywords tag on the page, these keywords are also searched as part of the knowledgebase search on the front end. It is useful to add alternative spellings or names for certain things, or common misspellings, to ensure that articles have the best chance of being found with the knowledgebase search.
