I've been scouring the site for a couple of days trying to figure out what I needed to install and where. I'm not using maven. The website doesn't give any idea of how to setup JBehave when not in a maven environment. So I'm having to do it by reverse engineering the maven pom.
The first problem was to trying and figure out what to download. The linked download file is only of use in a maven world. So I had to start downloaded by surfing the online repos. So I'd suggest that the raw jars and zips should also be linked for download from the main site.
The second issue was what to unzip, etc and suggested directories. Again the documentation takes a "it will just work" approach, which it doesn't. So instructions are needed here to.
