+ *
+ *  \subsection SSec_LinuxInstallation Linux Installation
+ *  On Linux systems, the programmer should be usable out of the box with no special setup other than (on some systems)
+ *  editing of the system permissions to allow the programmer to be used from a non-elevated (root) context. The programmer
+ *  is compatible with the free open source AVRDude programming software project.
+ *
+ *  \subsection SSec_WindowsInstallation Windows Installation
+ *  On Windows systems, due to an unfortunate limitation of the USB AVR devices and the driver used in the official AVR
+ *  Studio/Atmel Studio platform, the programmer cannot be made compatible with AVRDude and AVR Studio/Atmel Studio at the
+ *  same time. Instead, the programmer will be compatible with the official Atmel software by default, with a recompilation
+ *  with the \c LIBUSB_DRIVER_COMPAT token (see \ref Sec_Options) being required to use the alternative libUSB driver
+ *  compatibility mode that will allow the programmer to work under AVRDude on Windows.
+ *
+ *  If compiled for Atmel Studio/AVR Studio compatibility, install the Jungo device drivers that ship with the Atmel software.
+ *  If compiled in the alternative libUSB compatibility mode for AVRDude use, install the libUSB drivers that are included
+ *  with your compiled copy of AVRDude, or create them using the libUSB-Win32 (http://sourceforge.net/projects/libusb-win32)
+ *  project.
+ *
+ *  For convenience, the programmer will report two different serial numbers depending on the firmware compatibity mode, so
+ *  that the correct driver can be installed for the matching firmware. If the \c RESET_TOGGLES_LIBUSB_COMPAT compile option
+ *  is used (see \ref Sec_Options) this allows for an easy way to automatically switch device drivers along with the firmware
+ *  compatibility mode.
