What is a cleanup?

A cleanup is exactly what the name says. It is a a method of cleaning up an article so that its quality will improve. Pages which look messy, have many grammatical errors, or which are poorly written can be listed as requiring a cleanup. Users will see that these pages are in need of assistance and will work on them to improve them.

Marking articles for cleanup

When you've found a page that requires a cleanup, you can then add the cleanup template. At the top of the page, simply add {{cleanup}}. Doing so will create this template at the top of the page:

Starman (Mario Kart Wii) This article may require a cleanup. Starman (Mario Kart Wii)
You can discuss this issue on the talk page or edit this page to improve it.

You can also add the page to the cleanup category by adding [[Category:Articles in need of cleanup]] at the bottom of the page. If the article is very large, then it might be a good choice to mention of the article's talk page that it is in need of a cleanup and explain why.
