Initial documentation for the kernel
    
    This documentation is by no means complete, but it's a place to start
    for pretty user-facing documentation for the kernel in Fedora. In
    addition to the basic export from the wiki, this includes various other
    related articles in the wiki which I thought might be good user-facing
    documentation.
