The guys at myTreo.net have done a font Software Installation Guide especially good for anyone new to the Palm community. "There are many different methods you can use to install software to your Palm device. What you choose ends up being a personal preference, or sometimes a matter of convenience. In this article, I will cover the various methods of installing software and the relative pros and cons of each. Before you install any software, it is a good idea to do a backup. That way if anything goes wrong, you have a restore point to go back to. This is particularly true if the application you are about to install is a Beta. Next, you need to decide whether you want to install the software to the device or to your SD card. Many applications can run just fine from the card, and keeping them on your card saves valuable space on your device. Applications that can run from the card include, but are not limited to, e-readers, some multi-media applications (like TCPMP), and most games."
