care and feeding of debian

Hans,

    This would have been a great help for me when I was putting Debian in my old 
Winbook laptop!  (Now if only I could get my sound working...)   I think it's 
a good cheat-sheet for the computer-literate.  For total newbies, it could 
probably use a bit of background explanation.
