How do I add Insteon devices?

[JJ]

I am running HG Version 1.1 beta r514. Ii is currently operating with a CM-15a and a few X10 lights. I would like to switch to an Insteon controller and Insteon devices. I installed the 2413U controller and can control the X10 devices with it but have not been able to find a way to add the Insteon devices.
Can someone supply a link to the appropriate docs or tell me how to do it please?

TIA,

[JJ]

Perhaps I asked the question wrong.

Does anyone use Insteon with HG for any purpose other than controlling X10 devices? If so, what devices do you control with it?
