No, you can't install anything from this link. It's source for developers. But it means in the next day or so the roll out of ND8 KitKat will begin OTA.
If this is anything like KitKat for the Note3 it will be a winner. My Note 3 got way faster when I updated to KitKat. It was the single biggest improvement I have ever seen on a device with an OS update and I started using Android when the Samsung Moment came out on Sprint !
