 # Overview
 
-A Balance 12 layout for the Atreus keyboard.
+This layout is based on Balance Twelve (mirror variant) by Sasha Viminitz. Please see [this page](https://mathematicalmulticore.wordpress.com/the-keyboard-layout-project/) 
+for more information. It's designed for left-handers who use their right hand for the mouse.
 
-Balance 12 was created by Sasha Viminitz. Please see [this page](https://mathematicalmulticore.wordpress.com/the-keyboard-layout-project/)
-for some background on the design of the layout.
+## To build
 
-* The variant used here is a mirror of the original for left-handers
-* The central column of punctuation keys has been moved elsewhere
-* Home positions for the left and right forefingers are *T* and *A* respectively
+```
+sudo make atreus:yttyx
+```
 
-## To build/flash
+## To flash (example)
 
-> make atreus:yttyx:avrdude
+```
