+# franky36
+
+Franky36 is 36 key compact handwired split keyboard that uses single RP2040-Zero controller.
+
+* Keyboard Maintainer: [Grigory Avdyushin](https://github.com/avdyushin)
+* Hardware Supported: RP2040-Zero
+* Hardware Availability: Handwired [franky36](https://github.com/avdyushin/franky36)
+
+Make example for this keyboard (after setting up your build environment):
+
+ make franky36:default
+
+Flashing example for this keyboard:
+
+ make franky36: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**: Hold down the reset button on the controller and plug in the keyboard
+* **Keycode in layout**: Press the key mapped to `QK_BOOT` if it is available
