Welcome to the wonderful world of the Entirely Generic Administration Derma! (and because E is superfluous, it's mostly just called the GAD)
Have you ever been using admin mods such as ULX or ASSMod and simply were not satisfied by the derma? Ever though there was more to life than an endless labyrinth of scrolldown menus or seas of buttons?
Well now there is! The GAD incorporates a familiar ULX-ish design with new innovations (sorry ASSMod, I hate your menu) to create the best administrating experience you could ask for, while allowing the old schoolers to keep with the times.
This download looks like an addon. You need to extract the downloaded zip and put the addon folder in your Garry's Mod addons folder. You should end up with a directory structure similar to below:
