how to use rockwool

Just got some but with no info on how to use it. Can someone help me?

tig,
Check with Brugcrazy....she knows all about rockwool.

Brugcrazy, where are you???
We get lots of rockwool next week and now I can`t decide, whether to plant in it or to isolate the house with it. I will do, what ever favors the brúgs *lol*

she sent me great instructions, I'll send them to you!!
