Gnome documentation wouldn't apply as it has its own desktop environment. Linux Deepin 12.12, based on Ubuntu 13.04, it has, Deepin Desktop Environment (DDE). Previously, Linux Deepin has used a highly customized GNOME Shell as the default desktop environment. They didn't update their manual to instruct on the Deepin Desktop Environment.
I want to change the icon in the panel and do advanced customizations.
