 By default, the `zmk-config` folder should contain two files:

 However, your config folder can also be modified to include a `boards/` directory for keymaps and configurations for multiple boards/shields
 outside of the default keyboard setting definitions.

 various config settings that can be commented/uncommented to modify how your firmware is built.

-## Building from a local `zmk` fork using `zmk-config`
-
-[As outlined here](development/build-flash.md), firmware comes in the form of .uf2 files, which can be built locally using the command `west build`. Normally,
-`west build` will default to using the in-tree .keymap and .conf files found in your local copy of the `zmk` repository. However, you can append the command, `-DZMK_CONFIG="C:/the/absolute/path/config"` to `west build` in order to use the contents of your `zmk-config` folder instead of the
-default keyboard settings.
-**Notice that this path should point to the folder labelled `config` within your `zmk-config` folder.**
-
-For instance, building kyria firmware from a user `myUser`'s `zmk-config` folder on Windows 10 may look something like this:
-
-```bash
-west build -b nice_nano -- -DSHIELD=kyria_left -DZMK_CONFIG="C:/Users/myUser/Documents/Github/zmk-config/config"
-```
+:::note
+It is also possible to build firmware locally on your computer by following the [toolchain setup](development/setup.md) and
+[building instructions](development/build-flash.md), which includes pointers to
+[building using your `zmk-config` folder](development/build-flash.md#building-from-zmk-config-folder).
