Program Attiny13a​​​​​​​ With Arduino

[Holy Hathaway1]

I'm programming ATtiny13A with arduino. 
I want to use "stepper.h" library but it seems it is only supported on arduino or atmega series but not on attiny. Is there any way I can fix it?

Thank you!

See section [047] here: https://blog.podkalicki.com/100-projects-on-attiny13/  else you could rewrite the stepper.cpp library file for the ATtiny13A.
