 # Default Plaid-Pad Layout
 
-This is the default layout that comes flashed on every Plaid-Pad.  
+This is the default layout for the plaid pad. 
 The upper left (7) and right (/) switch, can be replaced by a rotary encoder.
-They do "Up Arrow" (KC_UP) and "Down Arrow" (KC_DOWN).  
-Encoder with build-in switch are supported.
+Encoders with built-in switch are supported and map to the original keys (7) and (/).
 
+The upper left encoder performs a tap on "Right Arrow" (KC_RIGHT) and "Left Arrow" (KC_LEFT)  when rotated clockwise and counter-clockwise in the respective direction for each step of the encoder. 
+
+The upper right encoder performs a tap on "Up Arrow" (KC_UP) and "Down Arrow" (KC_DOWN) when rotated clockwise and counter-clockwise in the respective direction for each step of the encoder.
