+
+The Cantor keyboard is a 42 key diodeless split keyboard, designed with simplicity in mind. It is inspired on the popular [corne](https://github.com/foostan/crkbd), [ferris](https://github.com/pierrechevalier83/ferris) and [sweep](https://github.com/davidphilipbarr/Sweep) keyboards, aiming to provide a more ergonomic (stronger column stagger) corne-like layout with a simple, easy to assemble and cheap design.
+
+* Keyboard Maintainer: [Diego Palacios](https://github.com/diepala)
+* Hardware Supported: Blackpill STM32F401
+* Hardware Availability: https://github.com/diepala/cantor
+
+Make example for this keyboard (after setting up your build environment):
+
+    make cantor:default
+
+Flashing example for this keyboard:
+
+    make cantor: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 top left key and plug in the keyboard. For the right side, hold the top right key and plug the keyboard.
+* **Physical reset button**:
