http://drazzy.com/package_drazzy.com_index.json

Copy link above to;
File>Preferences>Additional Board Manager URL's  copy here and click ok.

Then open Tools>Board>Board Manager

Then connect attiny2313 with arduino like shown below.



ATtiny pin 1   arduino pin 10 reset
ATtiny pin 17 arduino pin 11 MOSI
ATtiny pin 18 arduino pin 12 MISO
ATtiny pin 19 arduino pin 13 SCK
ATtiny pin 10 arduino GND
ATtiny pin 20 arduino VCC


Open File>Samples>ArduinoISP

From Tools choose Arduino Uno, connected port and programmer to AVRISP MKII

Upload

Open File>New

Choose "ATtiny 2313/4313" from Tools>Board 

Choose "ATtiny2313" from Chip

Choose "8mhz(internal)" from Clock

Choose programmer as "Arduino as ISP" 



And we can upload our sample code

void setup(){
pinMode(7, OUTPUT);
}
void loop(){
digitalWrite(7, HIGH);
delay(10);
digitalWrite(7, LOW);
delay(10);
}
