+Hexwire's Let's Split Layout
+============================
+
+### Changes from default layout
+
+- Main layer
+    - The right space bar key has been changed to backspace, as I only hit space with my left thumb
+    - Backtick is at the lower right and also serves goes to the 3rd function layer when held
+    - Enter key acts as shift when held
+    - Escape key acts as control when held
+    - Minus key at upper right
+- Lower layer
+    - Numbers are on the lower layer, to make it easier to use a numpad on the right hand
+    - Arrow keys
+    - Straight and curly brackets in the middle two columns
+    - Screenshot keys for MacOS
+- Upper layer
+    - Symbols are on the upper layer
+    - Media keys
+    - Page Up/Down, Home/End
+- 3rd function layer
+    - Function keys
+
