Now you understand that what is a bootloader is and what are the benefits of a bootloader. Inspired by many online tutorials, now I am giving you an introduction to install a bootloader into your own ...

AVR microcontrollers without a bootloader must be programmed through the SPI, as described above. All microcontrollers (at least, those with datasheets) have a pinout schematic and pin description.

So [Dean] wrote a parser for the bootloader which could accept the incoming hex code and write it to the chip’s program memory.
