+
+A replacement PCB for Duck Octagon 75% keyboard.
+
+* Keyboard Maintainer: [Mechlovin' Studio](https://github.com/mechlovin)
+* Hardware Supported: Duck Octagon, APM32F103
+* Hardware Availability: [Duck Octagon](https://geekhack.org/index.php?topic=102142.0)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make mechlovin/olly/octagon:default
+
+Flashing example for this keyboard:
+
+    make mechlovin/olly/octagon: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 (Escape) and plug in the keyboard
+* **Bootloader reset**: Hold down the key at (0,14) in the matrix (Backspace) and plug in the keyboard
+* **Keycode in layout**: Press the key mapped to `RESET` if it is available
+* **Hardware reset**: Press reset button (located on the bottom side of the PCB)
