How do I use this .ttf file as my terminal font?

http://unix.stackexchange.com – I'm using Linux Mint 13, with Cinnamon. I have a .ttf file that I'm trying to use as my terminal font. I figured the directory for terminal fonts is /usr/share/fonts/truetype/msttcorefonts/ so I copied my .ttf file there. However, it doesn't show up in the terminal preferences font list. What am I doing wrong? (HowTos)
