+# test_duplex_dp
+
+
+
+A short description of the keyboard/project
+
+* Keyboard Maintainer: [Takeshi Nishio](https://github.com/yourusername)
+* Hardware Supported: The PCBs, controllers supported
+* Hardware Availability: Links to where you can find this hardware
+
+Make example for this keyboard (after setting up your build environment):
+
+ make test_duplex_dp: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).
