+ *  microcontrollers to act as a clone of the official Atmel AVRISP-MKII programmer, usable within AVRStudio. In its\r
+ *  most basic form, it allows for the programming of 5V AVRs from within AVRStudio with no special hardware other than\r
+ *  the USB AVR and the parts needed for the USB interface. If the user desires, more advanced circuits incorporating\r
+ *  level conversion can be made to allow for the programming of 3.3V AVR designs.\r
  *\r
  *  This device spoofs Atmel's official AVRISP-MKII device PID so that it remains compatible with Atmel's AVRISP-MKII\r
  *  drivers. When promted, direct your OS to install Atmel's AVRISP-MKII drivers provided with AVRStudio.\r
  *\r
+ *  Note that this design currently has several limitations:\r
+ *    - Minimum target clock speed of 500KHz due to hardware SPI used\r
+ *    - No VTARGET detection and notification\r
+ *    - No reversed/shorted target connector detection and notification\r
+ *\r
  *  \section SSec_Options Project Options\r
  *\r
  *  The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value.\r
