I downloaded a file that is called
Gimp-help-2.8.0.tar.bz2. I put it on my desktop.
I'm running Ubuntu 12.04 I understand that there is something that has to be done to this file before I can use it. It's a manual on how to use the Gimp.
I'm not to familiar on how to work with this file as I'm a newbie with Ubuntu.
Thank you for your help.
