+
+Gasket mounted 40% column staggered keyboard manufactured by Yushakobo
+
+* Keyboard Maintainer: [foostan](https://github.com/foostan/)
+* Hardware Supported: Cornelius PCBs
+* Hardware Availability: http://github.com/foostan
+
+Make example for this keyboard (after setting up your build environment):
+
+    make foostan/cornelius:default
+
+Flashing example for this keyboard:
+
+    make foostan/cornelius:default:flash
+
+The board reset into bootloader mode via either the reset button (on the back of the PCB) or a configured `QK_BOOT` shortcut (which may vary depending on when the PCB was flashed).
+
+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).
