Help! My kids threw away my instructions for wine making and I need to know what the next step is?

My first foray into wine making and my kids managed to throw away my instructions!

The wine has just finished fermenting and I’ve agitated the heck out of it (to release any residual co2). Now I’m supposed to add either:

a) stabilizer
b)keiselsol
c) chitosan

I have packages for all three. But I don’t know in what order I’m supposed to add them or in what intervals.

Can someone please try to walk me through the last stages?
