+
+I. Building the meta-{{=machine}} BSP layer
+========================================
+
+--- replace with specific instructions for your layer ---
+
+In order to build an image with BSP support for a given release, you
+need to download the corresponding BSP tarball from the 'Board Support
+Package (BSP) Downloads' page of the Yocto Project website.
+
+Having done that, and assuming you extracted the BSP tarball contents
+at the top-level of your yocto build tree, you can build a
+{{=machine}} image by adding the location of the meta-{{=machine}}
+layer to bblayers.conf, along with any other layers needed (to access
+common metadata shared between BSPs) e.g.:
+
+ yocto/meta-xxxx \
+ yocto/meta-xxxx/meta-{{=machine}} \
+
+To enable the {{=machine}} layer, add the {{=machine}} MACHINE to local.conf:
+
+ MACHINE ?= "{{=machine}}"
+
+You should then be able to build a {{=machine}} image as such:
+
+ $ source oe-init-build-env
+ $ bitbake core-image-sato
+
+At the end of a successful build, you should have a live image that
+you can boot from a USB flash drive (see instructions on how to do
+that below, in the section 'Booting the images from /binary').
+
+As an alternative to downloading the BSP tarball, you can also work
+directly from the meta-xxxx git repository. For each BSP in the
+'meta-xxxx' repository, there are multiple branches, one corresponding
+to each major release starting with 'laverne' (0.90), in addition to
+the latest code which tracks the current master (note that not all
+BSPs are present in every release). Instead of extracting a BSP
+tarball at the top level of your yocto build tree, you can
+equivalently check out the appropriate branch from the meta-xxxx
+repository at the same location.
+
+
+II. Booting the images in /binary
+=================================
+
+--- replace with specific instructions for your platform ---
+
+This BSP contains bootable live images, which can be used to directly
+boot Yocto off of a USB flash drive.
+
+Under Linux, insert a USB flash drive. Assuming the USB flash drive
+takes device /dev/sdf, use dd to copy the live image to it. For
+example:
+
+# dd if=core-image-sato-{{=machine}}-20101207053738.hddimg of=/dev/sdf
+# sync
+# eject /dev/sdf
+
+This should give you a bootable USB flash device. Insert the device
+into a bootable USB socket on the target, and power on. This should
+result in a system booted to the Sato graphical desktop.
+
+If you want a terminal, use the arrows at the top of the UI to move to
+different pages of available applications, one of which is named
+'Terminal'. Clicking that should give you a root terminal.
+
+If you want to ssh into the system, you can use the root terminal to
+ifconfig the IP address and use that to ssh in. The root password is
+empty, so to log in type 'root' for the user name and hit 'Enter' at
+the Password prompt: and you should be in.
+
+----
+
+If you find you're getting corrupt images on the USB (it doesn't show
+the syslinux boot: prompt, or the boot: prompt contains strange
+characters), try doing this first:
+
+# dd if=/dev/zero of=/dev/sdf bs=1M count=512
