I've had this headache for the last day now trying to install this damn XFBML Facebook Like Button.

I am by no means a master yet but I sort of know my way around building a website yet this whole process has me feeling as dumb as a drunken caveman.\
They say "install" the Javascript SDK.. so I download the files on Github. unzip my files to the desktop.. then I see this folder with files in it... html files, demo
