Frage zur Installation von FRAMEBUFFER

[Christian72D]

In der CommandRef steht:

You need to have the perl module GD installed. This module is most likely not available for small systems like Fritz!Box.

FRAMEBUFFER uses RSS to create an image that is displayed on the framebuffer.
The binary program fbvs is required to display the image. You can download it from github.

Was genau muß ich bei github runterladen? Und wie installiere ich das?
Und reicht ein "sudo apt-get instatt GD"?
