+## 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 press the button on the back of the PCB - some may have pads you must short instead
+- **Keycode in layout**: Press the key mapped to `QK_BOOT` if it is available
