QLprism/elo ranks

[*QLuser]

Hi, I had a script for firefox called "QLRanks: In-game Elo Announcer".
Is it possible to use it for QLprism?
I know we can see the elo on people in the server before to join it in QLprism, but I would like to be able to see it when I am in the server.
Can someone explain me how to do that? (A kind of step by step tutorial in a simple english could be great )

follow instructions (step by step) in the readme file :>
just a bind that is needed works same as if used greasemonkey with firefox etc......
