 # ZMK Corne Keyboard Layout
 
-This this my personal [zmk](https://github.com/zmkfirmware/zmk) config for my [corne keyboard](https://github.com/foostan/crkbd), the firmware is built to work with the following devices.
+This this my personal [zmk](https://github.com/zmkfirmware/zmk) config for my
+[corne keyboard](https://github.com/foostan/crkbd), the firmware is built to
+work with the following devices.
 
 - Keyboard: Corne 6 column
 - Controller: nice!nano v2 + nice!view (for both left and right keyboard)
 - Dongle: Seed Xiao nRF52840
 
-> This is a dongle setup with zmk studio support. Left and Right keyboard both acts as peripheral and seed xiao as the main controller. This increases the battery life of the left board compared to when it is used as both main and left peripheral.

+
+## Installing Firmware
+
+Whether you built it yourself or downloaded my prebuilt firmware, it should
+contain the following files:
+
+For the Dongle (XIAO):
+
+- xiao_dongle.uf2
+- xiao_reset_settings.uf2
+
+For Keyboard (Corne):
+
+- nano_corne_left.uf2
+- nano_corne_right.uf2
+- nano_reset_settings.uf2
+
+> The `*_reset_settings.uf2` file is used to clear persistent settings like
+> default layers, BLE pairings, and other saved data that may remain after
+> repeatedly flashing new firmware.
+
+### Steps
+
+1. Plug in your XIAO dongle to your computer.
+2. Double-press the small button on the XIAO to enter bootloader mode.
+3. Copy `xiao_reset_settings.uf2` to the XIAO's root folder. (Optional, but
+   recommended to ensure a clean slate.)
+4. You’ll see an error after flashing—this is normal. Unplug and replug the
+   XIAO.
+5. Double-press the button again to re-enter bootloader mode.
+6. Copy `xiao_dongle.uf2` to the root folder of the XIAO.
+7. Wait for the error, then unplug the XIAO dongle. Done flashing the dongle for
+   now.
+8. Plug in your left Corne keyboard (it doesn't need to be turned on).
+9. Double-press the side button to enter bootloader mode.
+10. Copy `nano_reset_settings.uf2` to the keyboard's root folder.
+11. After the error appears, unplug and replug the keyboard.
+12. Double-press the button again to go back into bootloader mode.
+13. Copy `nano_corne_left.uf2` to the device. (Make sure to use the correct left
+    firmware!)
+14. Unplug after the error, then repeat steps 8–13 for your right Corne using
+    `nano_corne_right.uf2.`
+15. Plug your XIAO dongle back in to your computer.
+16. Turn on both sides of your keyboard. Enjoy!
