+# Ergodox Dvorak Layout with emacs binding in mind - software version
+
+This configuration is the same as the dvorak_emacs layout, but using a sofware dvorak configuration
+instead of a firmware configuration. This layout is for those who run their computer in dvorak mode.
+
+ * Control & Alt key on the thumbs (activated if pressed with another key).
+ * In the same way, "U" and "R" are the shift modifier if pressed with another key.
+ * "I" and "D" set the layer 1 for the auxiliary keys if pressed with another key.
+ * Software layout set to english.
+
+## Keymap Layers
+ - L0: dvorak with some customizations (see layout below)
+ - L1: auxiliary keys (includes function keys, numpad...)
+
+
+### Keymap 0: Base layer
+Keys with double values (like U/LSft) correspond to the 'tapped' key and the 'held' key, respectively
