+
+QMK for Megalodon DOIO Dual Layer Knob 3 Key macropad.
+
+* Keyboard Maintainer: [clownfish-og](https://github.com/clownfish-og)
+* Hardware Supported: DOIO KB03-01 using APM32F103CBT6 (clone STM32F103CBT6)
+* Hardware Availability: https://www.keebmonkey.com/products/megalodon-dual-layer-knob-macro-pad
+
+Make example for this keyboard (after setting up your build environment):
+
+    make doio/kb03:default
+
+Flashing example for this keyboard:
+
+    make doio/kb03: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
