-These configuration files were based off the Atreus keyboard. It assumes a Pro Micro is being used, however retains the 'make upload' feature from the Atreus branch. This keyboard uses a completely different 'matrix scan' system to other keyboards, it relies on an external nRF51822 microcontroller maintaining a matrix of keystates received from the keyboard halves. The matrix.c file contains the code to poll the external microcontroller for the key matrix. As long as this file is not changed, all other QMK features are supported.
+Some circuit board manufacturers including [DirtyPCBs](https://dirtypcbs.com/) and [PCBWay](https://www.pcbway.com/) offer a steeply discounted "prototyping" rate for a small quantity of identical circuit boards less than 100x100mm in size. The Mitosis was designed to take advantage of this, so that individuals might affordably manufacture their own without waiting for a group-buy.

+This keyboard uses a completely different 'matrix scan' system than most other keyboards supported by QMK. Here, QMK runs in a Pro Micro on a receiver module, and communicates only with an nRF51822 microcontroller module that in turn does wireless communication. The nRF51822 maintains a matrix of keystates received from the same microcontrollers on each of the keyboard halves. The matrix.c file contains the code to make the Pro Micro poll the external wireless microcontroller for the key matrix. As long as this file is not changed, all other QMK features are supported.
