How to add a new APP in Admob for WP8

[Sun Fremont]

Hi
  I would like to test ads on WP8.
But I can't find where to add a new Site/App for WP8 .
Is Admob still support WP8?
  by the way. I download the latest Admob SDK for WP8 below
https://developers.google.com/mobile-ads-sdk/download
 But I can not add reference lib in my WP8 project .
I use Win Phone 8 SDK with VS 2012 Express on Win 8.1 .
 Is anyone have idea ?
