how to pick up a patch from a mail

Hi Say I want to pick up a patch https://www.google.co.in/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&ve... how do i apply it directly to my branch without copying it ? I have tried git am and git mail-info, but i am not sure if I am using the correct command. Can you please let me know the correct command ? -- Thanks & Regards ~/asd
