Forum:From where does the Google search pull the "tag lines" for the Wikia?

Questions
Where does Google get the tag lines for the wikia that it shows when you do a Google search on the main Wikia page?

For example, a search for the "Home" wikia, pulls up
 * Home Wiki
 * home.wikia.com/Home Wiki is a community site that anyone can contribute to. Discover, share and add your knowledge!

This generic description doesn't say anything about what this wiki is for, and this text doesn't exist on the Home wikia. (If that text was ever used to describe this wiki, it's been years since it was changed.) So, where is it coming from, and what can I do to get it changed to something useful? -- CocoaZen 19:49, October 1, 2011 (UTC)


 * Probably MediaWiki:Description--Sxerks 21:09, October 1, 2011 (UTC)


 * I think you're correct. I'll try changing that.  Thank you!  (Funny that didn't come up in a search of all the namespaces.)  -- CocoaZen 21:14, October 1, 2011 (UTC)


 * You should read this guide, is really helpful and explain the use of some MediaWiki pages, such as Mediawiki:Description.
