+# Let's Split the Atreus
+
+This keymap is a port of the Atreus keymap to the Let's Split keyboard, using a
+similar method of handling layer switches as the `default` keymap.
+
+
+# Layers
+
+The following tables are the layers as implemented.
+
+### Underscores in Layer
+
+Any underscore represents a key that is mapped to `KC_NO`, or no keypress. The
+2x3 block in the middle is like this because the Atreus does not have any keys
+there. It has been left blank for the user to add her own special keypresses or
+macros that she finds useful to have on that particular layer.
+
