    This converter uses AVR's internal pull-up, but it seems to be too weak, in particular when you want to use a long or coiled cable.
    The external pull-up resistor(1K-10K Ohm) on Data is strongly recommended.

 LOCKING CAPSLOCK
 ----------------
 Many of old ADB keyboards have mechanical push-lock switch for Capslock key and this converter supports the locking Capslock key by default. See README in top directory for more detail about this feature.

 Notes
 -----
-Many ADB keyboards has no discrimination between right modifier and left one,
+Not-extended ADB keyboards have no discrimination between right modifier and left one,
 you will always see left control even if you press right control key.
-Apple Extended Keyboard and Apple Extended Keyboard II are the examples.
-Though ADB protocol itself has the ability of distinction between right and left.
-And most ADB keyboard has no NKRO functionality, though ADB protocol itself has that. 
-See protocol/adb.c for more info.
+Apple Extended Keyboard and Apple Extended Keyboard II can discriminate both side
+modifiers except for GUI key(Windows/Command).
+
+And most ADB keyboard has no diodes in its matrix so they are not NKRO,
+though ADB protocol itself supports it. See protocol/adb.c for more info.
+
+If keyobard has ISO layout you need to use ISO keymap with `make KEYMAP=iso`. With ANSI
+keymap you will suffer from swapped keys problem.
