 ## Kconfig
 
-The `CONFIG_ZMK_USB_LOGGING` KConfig value needs to be set, either by copy and pasting into the `app/prj.conf` file, or by running
-`west build -t menuconfig` and manually enabling the setting in that UI at `ZMK -> Advanced -> USB Logging`.
+The `CONFIG_ZMK_USB_LOGGING` Kconfig enables USB logging. This can be set at the keyboard level, typically in the `config/<your_keyboard>.conf`
+file if you are using a [user config repository](user-setup.md). It can also be enabled at the ZMK level using the `app/prj.conf` file, or other
+search locations described in the [configuration overview](config/index.md#config-file-locations).
+
+Logging can be further configured using Kconfig described in [the Zephyr documentation](https://docs.zephyrproject.org/3.2.0/services/logging/index.html).
+For instance, setting `CONFIG_LOG_PROCESS_THREAD_STARTUP_DELAY_MS` to a large value such as `8000` might help catch issues that happen near keyboard
+boot, before you can connect to view the logs.
 
 :::note
-If you are debugging your own keyboard in your [user config repository](user-setup.md), use
-`config/boards/shields/<your_keyboard>/<your_keyboard>.conf` instead of `app/prj.conf`. In Github

+In Github Actions, you can check the `<Keyboard> Kconfig file` step output to verify the options above have been enabled
 for you successfully.
