Optional System Installation Instructions

[ChristianWilkie]

Not sure if this is helpful for anyone, but I was looking for a way to "install" this so I could use it for multiple classes instead of copy/pasting it places. Using Ubuntu 20.10 groovy with LatTeX workshop/VSCode. Ended up doing the following

1. git clone jdf into /usr/share/texmf/tex/latex/jdf
2. run "texhash"

Thanks for making this available, quite helpful for writing reports for my OMSCS classes
