clustering, origin/edge docs

hi all , where can I find step by step guide for clustering FMS ?

only things I find is here :

http://livedocs.adobe.com/fms/2/docs/wwhelp/wwhimpl/js/html/wwhelp.htm?href=Part_Edge_Server.html

but ,  it is not clear what exactly to do , it just says like :

"

1. Install and configure the first Flash Media Server.

   Use the same serial number and license file each time you install Flash Media Server.

   NOTE

   A special cluster license file is required. For more information, contact your Macromedia representative.

2. Confirm that this Flash Media Server instance is working correctly.
3. Configure the Flash Media Server instance as an origin server.
4. Install and configure the next Flash Media Server in the cluster.
5. Configure this Flash Media Server instance as an edge server.
6. Make sure this edge server points to the origin server.
7. Repeat steps 5 through 7 for each edge server that your license file allows. "
8. .................

is there a step by step guide on how to do those things ?

Thanks
