Integration? You mean what happens when you click the "Enable iTunes support" option in Limewire?
Well, if all goes well, then Limewire creates a playlist in iTunes and whenever there's a new download, then Limewire will automatically open iTunes and have it import the song. You'll end up with two copies of the song: one in the Shared folder and the other in your Music directory.
You don't have to do anything other than tick the box to enable the function then click Apply for this to happen.
