It is a generally accepted standard that editors should attempt to follow, though it is best treated with common sense, and occasional exceptions may apply. Any substantive edit to this page should reflect consensus. When in doubt, discuss first on the talk page.
This page in a nutshell: An article too short and incomplete to provide more than rudimentary information about a subject should be marked as a stub by adding a stub template from the list here to the end of the article. Anyone can edit a stub article, or remove a stub template from an article which is no longer a stub.
A stub is an article deemed too short and incomplete to provide encyclopedic coverage of a subject. This page provides a general guide for dealing with stubs: the first section, Basic information, contains information that is recommended for most users; and the second section, Creating stub types, contains more specialized material. Existing stub categories can be found at Wikipedia:WikiProject Stub sorting/Stub types.
