RDoc template customization

how can I change my default RDoc template for my gem environment.

I'd like my gem server to look like this RDoc: http://getcloudkit.com/api/ and I've seen that des开发者_StackOverflow社区ign around so this shouldn't be so difficult.

if you like to have a RDoc template like http://getcloudkit.com/api/ you need to install and use Hanna by Mislav Marohnić to generate your docs. check it out here: http://github.com/mislav/hanna
