homemade soymilk Answered

I looked for an instructable on how to make soymilk but couldnt find one. how do I request one? do I cook the beans before I grind them? how finely do they have to be ground? how much water do I add? how long must it cook? whats the best way to strain it when I'm done. what can I add to sweeten it and give it some flavour?
