Once you have your handy collection of True Type fonts, you are going to want to create a directory to hold them. Installing the fonts system-wide will give all users access to them.

If the ~/.fonts directory doesn’t exist, create it with mkdir ~/.fonts (while logged into the specific users’ accounts).
