Forum:Short description for the google result

How do you change the description of your wiki on the google results page? For Example, Coaster Wiki says: "Coaster Wiki is a community site that anyone can contribute to. Discover, share and add your knowledge!"
 * Edit MediaWiki:Description. Once again, ensure it contains a lot of keywords. Mark  ( talk ) 22:46, July 9, 2010 (UTC)
