I tried to follow the instructions on how to get this going on my own but that talked about creating the web fonts from OpenType or something while the Font Awesome package comes with all those types by default. I figured better bring this to the experts over here instead of screwing something up.
I did make a font.ini file for what its worth....
[FontAwesome] version=4.4.1 2015 license=OFL-1.1 licensefile=OFL.txt url=http://fontawesome.io/ request-url=https://phabricator.wikimedia.org/T105630 ttf=fontawesome-webfont.ttf eot=fontawesome-webfont.eot woff=fontawesome-webfont.woff ;Also included in Font Awesome package but not installed ;otf=FontAwesome.otf ;svg=fontawesome-webfont.svg ;woff2=fontawesome-webfont.woff2
... but wasn't sure about the language setting. Since most will easily recognize some of the stuff one can pull from this font-family as it is, it didn't make any sense (to me) not to make it universally available if possible.
