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 ?
Thanks.

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.
Thanks.
