Adding Custom Font to Site Title for Moksha Template

I am having difficulties finding the code to add a custom font for my site title on the Moksha template. Some of the code I've found from other answers (for other templates) don't seem to be working. Help please?

@font-face {
	font-family: Tuan;
	src: url(paste font url here);
}

}
