 Apart from the traditional way of re-flashing the SD card or the eMMC from scratch, it's also possible to use RAUC to update.
 This method preserves the U-Boot version and the U-Boot's environment.

+### Initial installation
+
+#### Clearfog
+
+On development boards with a µSD card slot, simply `dd` the `images/sdcard.img` to the SD card and boot from there.
+
+On a regular Clearfog Base with an eMMC, one has to bootstrap the device first.
+If recovering a totally bricked board, one can use the `kwboot` command to upload the initial U-Boot via the console:
+
+```sh
+./tools/kwboot -b ./u-boot-spl.kwb -t -p /dev/ttyUSB0
+```
+Once in U-Boot (a stock factory image is OK as well), plug a USB flash disk which contains `images/usb-flash.img` and execute:
+
+```sh
+usb start; fatload usb 0:1 00800000 boot.scr; source 00800000
+```
+
+A Linux session will start.
+Run the following from the shell prompt:
+
+```sh
+mount /dev/sda1 /mnt; sh /mnt/usb-reflash-factory.sh
