+Maintainer: Leon Anavi <leon.anavi@konsulko.com>
+
+Disclaimer
+==========
+
+Note that this is just an example layer that shows a few possible configuration
+options how RAUC can be used.
+Actual requirements may differ from project to projects and will probably need
+a much different RAUC/bootloader/system configuration.
+
+Also note that this layer is for demo purpose only and does not care about
+migratability between different layer revision.
+
+I. Adding the meta-rauc-beaglebone layer to your build
+=======================================================
+
+Run 'bitbake-layers add-layer meta-rauc-beaglebone'
+
+II. Build The Demo System
+=========================
+
+::
+
+   $ source oe-init-build-env
+
+Set the ``MACHINE`` to the model you intend to build for. E.g.::
+
+   MACHINE = "beaglebone-yocto"
+
+Add configuration required for meta-rauc-beaglebone to your local.conf::
+
+   # Settings for meta-rauc-beaglebone
+   IMAGE_INSTALL:append = " rauc"
+   IMAGE_FSTYPES:append = " ext4"
+   IMAGE_BOOT_FILES:append = " boot.scr"
+   WKS_FILE = "beaglebone-yocto-dual.wks.in"
+
+Make sure either your distro (recommended) or your local.conf have ``rauc``
+``DISTRO_FEATURE`` enabled::
+
+   DISTRO_FEATURES:append = " rauc"
+
+It is also recommended, but not strictly necessary, to enable 'systemd'::
+
+   INIT_MANAGER = "systemd"
+
+Build the minimal system image::
+
+   $ bitbake core-image-minimal
+
+III. Flash & Run The Demo System
+================================
+
+You can either flash using bmaptool (recommended)::
+
+  $ bmaptool copy /path/to/core-image-minimal-beaglebone-yocto.wic.xz /dev/sdX
+
+or bzcat::
+
+  $ bzcat /path/to/core-image-minimal-beaglebone-yocto.wic.xz | dd of=/dev/sdb
+
+Then power-on the board and log in.
+To see that RAUC is configured correctly and can interact with the bootloader,
+run::
+
+  # rauc status
+
+IV. Build and Install The Demo Bundle
+=====================================
+
+To build the bundle, run::
+
+  $ bitbake update-bundle
+
+Copy the generated bundle to the target system via nc, scp or an attached USB stick.
+
+On the target, you can then install the bundle::
+
+  # rauc install /path/to/bundle.raucb
