 For other uses it's recommended to base images on `core-image-minimal` or
 `core-image-base` as appropriate. The old image names (`rpi-hwup-image` and
 `rpi-basic-image`) are deprecated.

+## WiFi firmware blobs
+
+Be aware that the WiFi firmwares for the supported boards are not provided by
+`linux-firmware` but by a custom recipe which only packages the needed blobs
+for these boards. This is because the upstream `linux-firmware` doesn't support
+or has outdated files for the blobs we need. The recipe
+`linux-firmware-raspbian` is based on a fork of `linux-firmware` which
+includes everything we need in order to fully support the WiFi hardware. All
+machines define `MACHINE_EXTRA_RRECOMMENDS` accordingly.
