Well, I know what to do with it now, so I don't need instructions. Late 2012 would have been the time to have instructions.
I remember when I first got TrueSpace, it came with at least one textbook sized manual, possibly two. They told you what to do with all of the floppies it came on, including the one with the "extra" (not necessary to run the program) stuff. Lightwave came with three manuals, all in .pdf format and I also bought a book called "Inside Lightwave 3D v10." None of that told me what to do with the Content disc. I Googled it and found no definitive answers, but I was able to find what I was looking for by looking around in the program after I found answers to other questions relating to the content directory on forums. That shouldn't be necessary, because they should tell you what to do with that stuff in the installation instructions.
