The Starter Wiki doesn't seem to have much content, so I'm proposing the obvious: more content! This would be generic stuff, since there are many different wikis with different topics. This would include:
== Templates ==
* Template:Infobox
** Template:Character
** Template:Book
** Template:Place
* Some basic licenses such as:
** Public domain
** Self
** CC-BY-SA-2.0
** CC-BY-SA-2.5
** CC-BY-SA-3.0
** Unknown
** GNU GPL
** GNU FDL
== MediaWiki interface messages ==
* MediaWiki:Licenses, filled out
* Basic category map
== Categories ==
A basic sitemap.
* Category:Sitemap
** Category:Templates
*** Category:Administrator templates
*** Category:Article templates
*** Category:Bot templates (maybe?)
