## Bootloader
Enter the bootloader in 3 ways:
* **Bootmagic reset**: Hold down the top left key and plug in the keyboard. This will also clear the emulated EEPROM, so it is a good first step if the keyboard is misbehaving.
* **Physical reset button**: Press the button on the back of the PCB twice in quick succession.
* **Keycode in layout**: Press the key mapped to `QK_BOOT`. In the pre-supplied keymaps it is on the second layer, in the bottom-right corner.
After entering the bootloader through one of the three methods above, the keyboard will appear as a USB mass storage device named `MT.KEY`. If the CLI is unable to find this device, the compiled `.uf2` file can be manually copied to it. The keyboard will reboot on completion with the new firmware loaded.
