+# Luddite
+
+Luddite 60% keyboard with backlight and RGB underglow.
+
+* [The original TMK firmware](https://github.com/di0ib/tmk_keyboard/tree/master/keyboard/luddite)
+
+Keyboard Maintainer: QMK Community  
+Hardware Supported: Luddite PCB  
+Hardware Availability: [Luddite project on 40% Keyboards](http://www.40percent.club/search/label/luddite)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make luddite:default
+
+See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
+
+First pass at adding support for the luddite keyboard. Compiles but completely
+untested. Intended to kick-start development.
