+
+![takashicompany/baumkuchen](https://i.imgur.com/NS39x44h.png)
+
+Baumkuchen is a 13-key macropad with a radial key layout.  
+The board can be used as a circuit or as a switch plate by cutting out the keyswitch Pro Micro part.  
+It is compatible with Cherry MX compatible keyswitches, and a rotary encoder can be optionally installed.  
+LEDs can also be mounted to make it glow.  
+The board is reversible, allowing you to choose the arrangement of keys and Pro Micro according to your usage style.
+
+* Keyboard Maintainer: [takashicompany](https://github.com/takashicompany)
+* Hardware Supported: Baumkuchen PCB, Pro Micro
+* Hardware Availability: https://github.com/takashicompany/baumkuchen
+
+Make example for this keyboard (after setting up your build environment):
+
+    make takashicompany/baumkuchen:default
+
+Flashing example for this keyboard:
+
+    make takashicompany/baumkuchen:default:flash
+
+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).
+
+## Bootloader
+
+Enter the bootloader in 3 ways:
+
+* **Bootmagic reset**: Hold down the key at (0,0) in the matrix (usually the top left key or Escape) and plug in the keyboard
+* **Physical reset button**: Briefly press the button on the back of the PCB - some may have pads you must short instead
+* **Keycode in layout**: Press the key mapped to `QK_BOOT` if it is available
