The fonts are embedded in the simple Cocoa demo application provided with the kit, but for development of your own projects you will need to copy the fonts to a suitable folder or install them on your system. You can Install them on your system as follows:
For OS-X 10.3
From the Applications list select the Font Book.
The Font Book Window displays 3 columns (Collection , Font and a sample of the font).
Select the All Fonts collection.
Open a second window displaying the contents of the dLSoft Font kit installation folder.
Drag all of the fonts from the Fonts folder in the dLSoft Font kit installation folder into the Fonts column of the Font Book
The fonts are now installed, so you can close the Font Book.
For OS-X 10.1 and 10.2
For the Hard disk folder open the Library folder.
Drag all of the fonts from the Fonts folder in the dLSoft Font kit installation folder into the Fonts folder in the Lbrary folder.
The fonts are now installed, so you can close the Library folder.
