Please refer this :

http://keycloak.github.io/docs/userguide/keycloak-server/pdf/keycloak-reference-guide-en-US.pdf

you will see chapter 
Chapter 3. Installation and Configuration of Keycloak Server

please follow these instructions and also you can verify the folder structure for both the extracted zip file as well as your local Jboss home (if you are using the existing Jboss). hope this helps.
