How to create server instances and then a cluster for JBoss AS 7.1.0 for Windows OS

I am unable to find any information on creating server instances on windows OS for JBoss AS7.1.0.
I have tried the other ways mentioned but nothing.
The admin console doesnot have any function of creating a server instance and I cant find any instruction for doing it through command prompt.
Also after creating the server instances how to you create the cluster and what are the steps for it. Then after that, what is the steps for creating a High Availability clustering

Thankyou in advance

Appreciate your help
