+# Quark_Plus
+
+![Quark_Plus](https://i.imgur.com/4TI6BA0h.png)
+
+The Quark Plus is a premium Quark for those that want more features of the original. It features support for 4 rotary encoders (it is recommended to use 1 per left and right side), LED backlighting, RGB underglow, JST connector, and compatibility for earlier revisions of your favorite ortholinear keyboard.
+
+* Keyboard Maintainer: [Nasp](https://github.com/npspears)
+* Hardware Supported: Quark_Plus
+* Hardware Availability: https://www.checkerboards.xyz
+
+Make example for this keyboard (after setting up your build environment):
+
+    make checkerboards/quark_plus:default
+
+To enter the bootloader, press the hardware button on the back of the PCB just to the left of the USB connector.
+
+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).
