facebook leaderboard for windows phone

Hi, i want to integrate leaderboard from facebook using facebook plugin for windows phone (it's for android,ios and web player but this guy manage to make it work for windows phone but his website not accessible) so is there any tutorial out there? i think it will be pretty much the same with android and ios so maybe someone can point me out a tutorial about making leaderboard? i just want facebook name,profil picture and score point
