[Freeswitch-users] How to start with js

Hi, I'm experimenting with freeswitch and want to build simple IVR in js, however I don't know how to set up freeswitch for it. I have mod_spidermonkey compiled already. Could anybody tell me what to do next? [I know, there are some examples scripts at http://www.freeswitch.org/eg/js/] Thanks in advance, Tamas
