+# Skewwhiffy keymap
+
+## Overview
+
+A small-form ergonomic Colemak-based multi-layered layout, optimized for software engineering. Programmed to emulate a standard UK ISO keyboard.
+
+Keyboard layout can be viewed [here](http://www.keyboard-layout-editor.com/#/gists/470f01e934c27d41491dea9ef5c6fde6)
+
+[![keyboard-layout.png](https://i.postimg.cc/BbDCYnzh/keyboard-layout.png)](https://postimg.cc/Lg9fh22f)
+
+## Default layer
+
+Colemak, with fingers right up to the edge of the keyboard. Layers and capital letters are accessed by holding down keys on the bottom row of letters (so, holding down Z will give you the capitals, holding down the X will give you the number layer).
+
+## Number layer
+
+Used to access numbers (on the right hand side of the keyboard) and function keys (on the left hand side of the keyboard). Hold down X or > to access.
+
+## Symbol layer
+
+Used to access symbols. Hold down C or < to access.
+
+## Navigation layer
+
+Used to access navigation and RGB control keys. Hold down V or M to access.
