 # Gherkin Wanleg Layout
 This is the layout I came up with to preserve a standard QWERTY 104 key ANSI layout as much as possible, in as few layers as possible for a 30 key board.  
-I originally set up a few Tap Dance keys, but dropped half of them in favor of chorded versions since in actual use, they tended to impede typing speed more than their current two-key versions.  
-I've left them in my `keymap.c` ready for use if anyone wants to try them out:
+Here are the two Tap Dance keys I've set up for this board:
 
-Legend Name | Single Tap | Double Tap | Hold
---- | --- | --- | ---
-*null* | space | enter | shift
-*null* | backspace | delete | control
+Legend Name | Single Tap | Double Tap | Hold  
+--- | --- | --- | ---  
 Sft//Cp | shift | caps lock | *null*
 Q//Esc | KC_Q | escape | *null*
