+
+# Default Mixi Layout
+
+This is the default layout that comes flashed on every Mixi macropad. Layer 1
+and Layer 2 are accessible by rotating the encoder. Layer 3 is not accessible
+by the encoder, instead is accessible by holding the [0,2] key on Layer 1. While
+Layer 3 is active, rotating the encoder will results in increasing/decreasing
+media volume. This layout is expected the encoder is on the left side or [0,0]
+key.
