Flashing shruthi-1 os files

Hi there,

completely newbie here regarding flashing of chips. I would like to flash the Shruthi OS using a tool like this one:

Is there any step by step flash tutorial available, similar to the one presented for the AMBIKA under option 2:

Maybe someone can sort out a total beginner.
