How do I use my yoghurt maker?

[Solarjunkie]

I have just dug out my old Bel yoghurt maker, to find I can't remember the proportion, time it takes etc. I remember I used to use evaporated milk, I have both that and a pot of live yoghurt; what happens next?
Also, I don't have any yogurt pots to put in it, what else can I use? Would plastic cups work? Or even poly styrene ones? - as I have some of each kind. I don't want to have to go & buy a six pack of yoghurt just to get the pots, my enthusiasm will cool if I do that!
TIA
