VB.net addin registry what goes in the Default Value ?

Hi,
I am creating a setup for an addin and i am trying to follow theinstructions for the help but i got stuck at the Default. It saysthat your suppose to type the value set by your add-in'sRegisterFunction function in Value.

I can't find where that is .

Can somebody kick me in the right direction.
