+# Duck Lightsaver V3
+
+
+
+Non official firmware for custom Korean keyboard with 96 key layout made by Duck.
+Group buy was run 2017 May via [geekhack](https://geekhack.org/index.php?topic=89546.0) and limited to 100 units.
+
+Keyboard Maintainer: [Rasmus Schults](https://github.com/rasmusx)
+Hardware Supported: Lightsaver PCB Ver 3.0, Atmega32u4
+Hardware Availability: [geekhack](https://geekhack.org/index.php?topic=89546.0)
+
+Make example for this keyboard (after setting up your build environment):
+
+ make lightsaver:default
+
+See [build environment setup](https://docs.qmk.fm/build_environment_setup.html) then the [make instructions](https://docs.qmk.fm/make_instructions.html) for more information.
+
+## Notes
+Thanks to Ralf Schmitt for previous implementations in his [TMK fork](https://github.com/xauser/tmk_keyboard/tree/xauser/) and few helping words.
