You need your hardware programmer to program the bootloader into the microcontroller You should also decide which communication protocol you want to use with your microcontroller (USB, RS232, etc).

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.
