 Also you should make the following change in ./hardware/tiny/cores/tiny/wiring.c to improve performance of the TinyWireS library:
 
-ISR(MILLISTIMER_OVF_vect)
+```ISR(MILLISTIMER_OVF_vect)
 {
   sei();
   // copy these to local variables so they can be stored in registers
   // (volatile variables must be read from memory on every access)
-
+```
 Basically add the line
-  sei();
+```  sei();```
 to the ISR(MILLISTIMER_OVF_vect) function so that it looks like above excerpt.
