How to get the ATTiny85 Boards Manager in Arduino

In my LED-Controller github repo, I've concentrated on using the ATTiny85 controller. This is due to the small footprint and the limited input and output needed to run the code.
I use Arduino www.arduino.cc... to upload the code. Find the board manager here raw.githubuser...

Hi Hugh thanks for that, I was wondering if you have used shift registers with an ATTiny85? I am asking because I am currently running 2*4 Solid State relays (8 outputs )on a nano using a breakout board, I would love to know enough to shrinkify that part of my project moving forward, keep up the videos “If you build it, they will come.” (definitely a Mandela effect!!!)

That's a great question. I have a shift register on hand with an array of LEDs set up. I'll hook up the ATTiny85 and give it a try!
