+# Planck
+
+A compact 40% (12x4) ortholinear keyboard kit made and sold by OLKB and Massdrop. A complete hardware rework of the Planck, sporting a faster and more powerful STM32 ARM Cortex-M4 microcontroller, with support for rotary encoders and three additional layouts. [More info on qmk.fm](http://qmk.fm/planck/)
+
+* Keyboard Maintainer: [Jack Humbert](https://github.com/jackhumbert)
+* Hardware Supported: Planck PCB rev6
+* Hardware Availability: [OLKB.com](https://olkb.com), [Massdrop](https://www.massdrop.com/buy/planck-mechanical-keyboard?mode=guest_open)
+
+Make example for this keyboard (after setting up your build environment):
+
+ make planck/rev6_drop: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).
