+**********************
+SolidRun Clearfog Base
+**********************
+
+This file documents Buildroot's support for the Clearfog Base by Solid Run.
+
+Vendor's documentation:
+https://wiki.solid-run.com/doku.php?id=products:a38x:documents
+
+Warning for eMMC variant of the MicroSoM
+========================================
+
+If you bought a MicroSoM version that includes an on-board eMMC flash, the
+built-in microSD card slot *WILL NOT WORK*. The Internet says that you have to
+upload the first bootloader via UART. This manual does not cover these steps;
+only MicroSoMs without the eMMC are supported.
+
+Limitations
+===========
+
+There's no access to the SPI flash in this combination of kernel/uboot/dts.
+
+Build
+=====
+
+Start with the default Buildroot's configuration for Clearfog:
+
+  make clearfog_defconfig
+
+Build all components:
+
+  make
+
+The results of the build are available in ./output/images.
+
+Create a bootable SD card
+=========================
+
+To determine the device associated to the SD card have a look in the
+/proc/partitions file:
+
+  cat /proc/partitions
+
+Buildroot prepares a bootable "sdcard.img" image in the output/images/
+directory, ready to be dumped on a microSD card. Launch the following
+command as root:
+
+  dd if=./output/images/sdcard.img of=/dev/<your-microsd-device>
+
+*** WARNING! The script will destroy all the card content. Use with care! ***
+
+For details about the medium image layout, see the definition in
+board/solidrun/clearfog/genimage.cfg.
+
+Boot the Clearfog board
+=======================
+
+Here's how to boot the board:
+
+- Set up the DIP switches for microSD boot. The correct values are:
+  1: off, 2: off, 3: ON, 4: ON, 5: ON. In this scheme, switch #1" is closer to
+  the ethernet ports and #5 is closer to the microSD card, "ON" means towards
+  the SOM, and "off" means towards the SFP cage.
+- Connect to the board's console over the microUSB port.
+- Insert the SD card into the slot on the board (pins up).
+- Power up the board.
