Hi, as some of you asked for a PDF MATE manual a MATE desktop documentation was found and added to our /Public folder on FTP server. Soon the booklet (39 pages) will be added to images for cloning.
The manual was taken from http://goinglinux.com/resources/Ubuntu%20MATE%20User%20Guide.pdf (under CC-BY-SA 4.0) and is available here as well http://ftp.labdoo.org/download/Public/manuals-ubuntu/English/Ubuntu%20MA....
Beside that PDF you can of cause use the MATE welcome tour as introduction, pre-installed on each MATE desktop.
