Sage9 beta2, how to add font awesome after theme created

Hi,

I started to use Sage9 yesterday, and it’s so cool!
I know that when I run ‘composer create-project roots/sage theme-name dev-master’ command, there will be an option to let user choose whether use font-awesome , I think I choosed ‘y’. but now I looked into assets/fonts/ folder there is no file. so my question is how can I add font awesome now.

Thanks,
William
