This video is pretty much all you need to get started with it:

You need to download two programs, - the AI Manager (where you choose which airlines you want) and the Traffic Controller (which runs while MSFS is running and injects the traffic). They are here (click the Software tab):

It's a bit fiddly at first but well worth the effort. Now you can have realistic traffic at world airports instead of those awful default planes.
So far I've only tried it in the UK but I'm sure it's fine here in NZ, - my only gripe so far is that it doesn't have Air Chathams yet.
Enjoy!
