Cannot add ATtiny2313 into Tool\Board

Hi every one,
I want to use Arduino as ISP with ATtiny2313 but I tried to experiment and read/download many articles ,but I still cannot add ATtiny2313 in.
I can only add ATtiny 44/45/84/85 into board.
So,I need some help from experts to advise me How to add it in Borad ?
My existing Aruino I had Arduino 1.0.6 and Arduino1.6.5.

Could some body , tell me how to do that ?

Preecha R.

Have you tried this one: GitHub - SpenceKonde/ATTinyCore: Arduino core for ATtiny 1634, 828, x313, x4, x41, x5, x61, x7 and x8

Thanks Pert,
I will try as you advised , I will do this on coming Sunday or Monday, due to I have busy jobs to clear.
Whenerver I’ve got its result will be feed back to you.
Thanks once again, Pert.

Hi Pert,
Now, I can see ATtiny xx including ATtiny x313 series on \Tools\Boards...
by using Arduino 1.6.5 and do the step as your reccommend web page.
but not test buy uploading ATtiny2313 yet.
