+# ErgoDox EZ Code Friendly Colemak Layout
+
+  _This layout was inspired by qwerty_code_friendly layout._ 
+
+  Having all the symbols accessible without modifiers is a good improvement for coding.
+
+  There are only two layouts which is easy to memorize.
+
+  There are two _"Super shifts"_, LNUM and RNUM, placed on the most convenient physical keys. Each of them act as shift for the opposite side of the keyboard, and as a modifier key for the current side (usage similar to AltGr in many national layouts). This is achieved by duplicating the corresponding parts of Layer 0 and 1 into Layer 3 and 4. As a bonus, pressing both keys toggles Caps-Lock.
+  
+  The numerical keypad is composed from regular number keys, works even in macOS.
