Native Instruments Guitar Rig 7 LE

stufisher

The above was included free in my recent purchase order to Thomann. I don't know anything about it so I'm after some guidance from the cognoscenti.

I'm rashly assuming that I need to download and activate on my laptop but after that I have no idea. The only music/editing thing I have on my laptop right now is Audacity.

what do I need to connect the laptop to?
do I use Native Instruments Guitar Rig 7 LE in conjunction with Audacity?
what additional kit will I need to make it all jive?
should I even bother with it in the first place?

I seriously haven't a clue so any advice will be mighty useful.

Ta muchly.
