+# Alchemist Keyboards is0GR
+
+is0GR Keyboard
+
+Keyboard Maintainer: [Andrew Kannan](https://github.com/awkannan)  
+Hardware Supported: STM32F072CBT6 or equivalent  
+
+Make example for this keyboard (after setting up your build environment):
+
+    make cannonkeys/is0gr:default
+
+Flashing example for this keyboard:
+
+    make cannonkeys/is0gr: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 (on this board - it's the only key) and plug in the keyboard
+* **Physical reset button**: Bridge the two pads labeled "RESET" on the top of the PCB using some tweezers, and hold the tweezers there until the board enters the bootloader mode
+* **Keycode in layout**: Press the key mapped to `QK_BOOT` if it is available (it isn't by default)
