[Amps] QSK for G-Grid amps

[Jibeji]

Hello.
I bought the QSK kit from http://www.somis.org/ but there is no 
explanation to install it in my SB200.
I tried to ask some questions to the author but a beginner like me can't 
understand his "two words" answers... I searched on the net for several 
days but I haven't found.
Could you please help me or tell me where can I find some documentation 
??? I'm totally lost.
Thank you
