+Instructions for adding the Gverb library to Interface
+(This is a required library)
+Clément Brisset, Octobre 22nd, 2014
+
+1. Go to https://github.com/highfidelity/gverb
+   Or download the sources directly via this link: 
+   https://github.com/highfidelity/gverb/archive/master.zip
+
+2. Extract the archive
+
+3. Place the directories “include” and “src” in interface/external/gverb 
+   (Normally next to this readme)
+
+4. Clear your build directory, run cmake, build and you should be all set.
