+# XD75 keymap
+
+This keymap has three base layers (QWERTZ, QWERTY, Gaming) and three function layers (Fn1, Fn2, Fn3).
+
+QWERTY is identical to QWERTZ except `z` and `y` are swapped.
+
+Gaming is a modified QWERTY layer for left-hand usage.
+
+The function layers contain:
+
+* Symbols (standard and Unicode)
+* Unicode input mode switches
+* Numpad
+* Function keys
+* Media, mouse, LED control
+* Non-breaking characters
