Thread:Extension talk:Capiunto/Tutorial or instructions?

I am a total newb at MediaWiki and am trying it out on a WIMP stack. MediaWiki 1.23.8 on IIS 7.5 PHP 5.6.5 (cgi-fcgi) MySQL 5.6.22-log Lua 5.1.4

After much frustration trying to get the Wikipedia infoboxe templates to work I decided to look into Capiunto. Got the extension and enabled it, but I am at a total loss for how to use it. I see here that it involves Lua code, but where am I supposed to put this? How do I use it?
