Hello there.  First time custom keyboard and not very literate in Arduino stuff...  I have flashed Arduinos before and built a 3D printer so not totally unfamiliar.
I am waiting for the Iris kit to arrive and meanwhile, I am learning about how to program the keyboard.
After reading and watching many videos, all I could find linked to Iris is the QMK interface.  When looking at the Ergodox, their interface is much more dummy friendly!  Can I use that or something like that on the Iris, giving that this kit comes with Pro Micro boards?  
Should I change the board for something different... if the actual keyboard PCB allows?
Sorry if this question is too trivial, I am a total noob on this.  I have done a search but couldn't find this answer.
Thanks in advance for any help!!
