Have a look at this example: http://stain.github.io/incubator-taverna-site/
This was generated with the Maven site plugin: from https://github.com/stain/incubator-taverna-site To generate it locally, use mvn clean site and look in target/site or mvn site:run to run a mini-sever on localhost. Note that relative links might be broken here. The biggest change was cleaning up the Markdown files that had invalid HTML in them, and to repeat hte menu in site.xml So there would be quite a downsizing in flexibility her e(unless you make your own skin) - but considerably easier to contribute to - I found it so much easier to edit and test locally.
