Which leads me to believe that if you want a steam pre-order, you must get it though the webshop.To activate your game code you must enter it into your Steam Client. If you don't already have Steam installed on your computer please visit http://store.steampowered.com/about/ to download and install the application.
Once installed, open and login to the Steam Application.
