Yep (I know). Thanks. I was using grep at first first (while mvn eclipse:eclipse was running)...

Would it be faster/easier to write a small HelloWorld Java example instead of the documentation, as a first step? Something people can just checkout, with all the right dependencies set, something people can just open with their favourite IDE and just run? Then you can add a document eventually. > If you want a 2min > stanbol example use the HTTP endpoint.
