The Debian Project (http://www.debian.org/) provides a number of guides and mailing lists which cater for different audiences. Reference has however only been made to documentation which is complete and up to date. Interested readers should consequently refer to The Debian Documentation Project's web page (http://www.debian.org/doc/ddp/) for details of work in progress.
