SEO description for the showwiki.php page

Just wondering where the place is to add the wiki description for this page showwiki.php ? My wiki is now indexing but I'm not sure if there is a spot to put the page description where?

Note< I don't have our wiki public and much content) just planning ahead.

Thanks!

Custom descriptions are only possible in VaultWiki for vBulletin 3. To avoid redundant behavior, this was removed in VaultWiki for vB 4. By default, vBulletin 4 constructs the wiki description using the page's introduction.

Thank you!
