+# Falcon AVR
+
+PCB using atmega32u4 for the Matrix Falcon
+
+* Keyboard Maintainer: [astro](https://github.com/yulei)
+* Hardware Supported: Matrix Falcon
+* Hardware Availability: Limited GB
+
+Make example for this keyboard (after setting up your build environment):
+
+    make matrix/falcon:default
+
+Flashing example for this keyboard:
+
+    make matrix/falcon: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 short cut the *RST* pin with the *GND* pin (pin at the topside of the *RST*) on the back of the PCB.
+* **Keycode in layout**: Press the key mapped to `RESET` if it is available.
