Step 2 Copy the .ttf, .otf or .fon extension file.
Step 3 Paste them in your computer's font folder.
Windows
C:\Windows\Fonts or C:\WINNT\Fonts
(can be reached as well by the Start Menu > Control Panel > Appearance and Themes > Fonts).
Mac OS X
/Library/Fonts (for all users),
or /Users/Your_username/Library/Fonts (for you only).
If your OS includes the Font Book, you can as well double-click on a font file, then a preview pops with an "Install font" button.
Linux
Copy the font files (.ttf or .otf) to fonts:/// in the File manager.
