Blinking led with assembly languague

I have some assignment from my lecture to blinking led using arduino uno with asstembly languague. How to blinking led using assembly languague?

void blink( ) {

asm volatile (
    "sbi    0x05, 0"  "\n\t"  // PORT B.0 high (I/O 8)
    // delay
    "cbi    0x05, 0"  "\n\t"  // PORT B.0 low
    // delay
};

}

This assumes the output pin as been declared an output already.
I've only complied this using avr-gcc - the IDE may require something else.

You will probably need to find the "AVR 8-bit Instruction Set Manual".
