Creating an IRd file

So I have a game that doesn't have an IRD file createed for it yet.  I checked, it wasn't on the library site.  I have a friend with a modded PS3 that can get the files off of it and decrypt the ISO.

A few questions:

-  How do I create an IRD file for the game once it's decrypted?

-  How do I get the IRD file onto the library website?  It would be good for everyone to have access to it.
