Unfortunately, most documentation for the moment is for developers.
However, we are happy to discuss the project, its vision and current software with prospective users and developers. You can reach us by sending mail to fenfire-dev@nongnu.org (mailing list fenfire-dev). Our IRC discussion takes place in channel #fenfire on the IRCNet servers (eg. irc.jyu.fi).
The project milestones document gives a summary of where we are at the moment.
