From MIKE2 Methodology
Stub Articles are very short articles, generally of one paragraph or less. Creating Stub Articles can provide a good approach when a Contributor to MIKE2.0 has a limited amount of time or feels their knowledge of an area is incomplete. If an article cannot be completed, sometimes a placeholder tables of contents is used to show the key areas to be covered when the article is more mature.
By writing a stub, you can help other Contributors get a better understanding of what you are looking for and it will generally help facillitate the process of getting a completed article.
Key aspects you may to include in a stub include:
To intiate a discussion around known changes to the article, use the article's Talk Pages.
To identify an article as a Stub, the Stub Template should be added to the top of the Article using the following text:
{{MIKE2 Stub}}
You can help also complete articles by looking through the the inventory of stub articles.
Wikipedia also uses the concept of Stub Articles to the same ends and provides a comprehensive description of this approach.
