Been setting up my Linux machine and getting everything setup the way I like it. I had to install a few fonts that I like using. Found the following info:

If ~/.fonts does not exist, create it:
$ mkdir ~/.fonts
Copy the font, from the command line, run the following:
$ cp [fontfile] ~/.fonts
From the command line, run the following:
$ fc-cache -f -v ~/.fonts
or alternatively, log out, and log back in.

Works great.. found on this site.
