 This is the README file for USBaspLoader.
 
 USBaspLoader is a USB boot loader for AVR microcontrollers. It can be used on
-all AVRs with at least 2 kB of boot loader section, e.g. the popular ATMega8.
-The firmware is flashed into the upper 2 kB of the flash memory and takes
-control immediately after reset. If a certain hardware condition is met
+most AVRs with at least 2 kB of boot loader section, e.g. the popular ATMega8.
+The firmware is flashed into the bootloader-section of the flash memory and
+takes control immediately after reset. If a certain hardware condition is met
 (this condition can be configured, e.g. a jumper), the boot loader waits for
 data on the USB interface and loads it into the remaining part of the flash
 memory. If the condition is not met, control is passed to the loaded firmware.
