Wikipedia:WikiProject Outlines/Wish list/Intro
Wikipedia contains outlines as hierarchical presentations of individual articles on a given topic.
An outline is a list of topics associated with a certain broader subject, arranged hierarchically to show the relationships between the topics, thereby showing the structure of the topic. Each outline is intended to help the reader become familiar with the subject it presents, and also serves as a table of contents or site map to that subject's coverage on Wikipedia.
