@ -463,12 +463,21 @@ you should be able to test with a build command like:
west build --pristine -b proton_c -- -DSHIELD=my_board
```
and then flash with:
The above build command generates `build/zephyr/zmk.uf2`. If your board
supports USB Flashing Format (UF2), copy that file onto the root of the USB mass
storage device for your board. The controller should flash your built firmware
and automatically restart once flashing is complete.
Alternatively, if your board supports flashing and you're not developing from
within a Dockerized environment, then you can test your build with:
```
west flash
```
Please have a look at documentation specific to
[building and flashing](build-flash) for additional information.
:::note
Further testing your keyboard shield without altering the root keymap file can be done with the use of `-DZMK_CONFIG` in your `west build` command,
shown [here](build-flash#building-from-zmk-config-folder)
