Where to place the USKCode files in Debian

Good evening,

First, I would like to mention that I am fairly new to linux and brand new to arduino. I have installed the Arduino IDE via apt-get and have downloaded the USKCode examples from Vilros.com. However, I am not sure where I need to place those files so that they actually show up within the IDE under File-->Examples-->USK Guide Code like the booklet indicates. Would anyone be able to assist me with this piece? Unfortunately, I am just not familiar enough with Linux to know where to drop those files.

Thank you for your help!
