+# Default keymap for grandiceps Keyboard
+
+Features:
+
+- Symmetric modifiers (CMD/Super, Alt/Opt, Ctrl, Shift)
+- Various modes, can be switched (using Adjust layer)
+- Modes for Qwerty and Colemak support
+- Modes for Mac vs Linux/Win support -> different order of modifiers and different action shortcuts on the "UPPER" layer .
+- The OLED on master half shows selected mode and caps lock state and is rotated.
