+## Danish (Dansk) layout for the Lily58 Pro
+Keyboard: Lily58 Pro  
+Keys: Lily58 Pro is 6×4+5keys column-staggered split keyboard, optinal with a rotary encoder.  
+Flash instructions: Flash each side of the keyboard, minding whether the side uses a Pro Micro or Elite-C controller.  
+
+### Layout
+Danish special characters on main layer, moving other characters to mainly raised layer.
+
+Layer 0 = default  
+Layer 1 = lower
