Making my own Knoppix Distribution

Hi!
I've been fooling around with linux for almost a year now and I tought it would be great to build my own Linux-distribution. I would like to start with something simple: editing knoppix by adding some programs and removing some others. Can anybody help me with an tutorial?

TIA

Have you checked the docs section of this site? You'll find tutorials there. Also a new howto on remastering was recently published here.
