A first documentation is online. Nothing great yet, but at least a lot better than nothing in my opinion: http://isdge.sourceforge.net/doc/
I also adjusted the projects website a bit, but it is still very ugly: http://isdge.sourceforge.net/
I basicly just wanted to put a link to the documentation somewhere wink.
