+Yocto BSP layer for the SanCloud boards
+=======================================
+
+Quick links
+-----------
+
+* [SanCloud website](https://www.sancloud.co.uk/)
+
+* [BeagleBone Enhanced Description](https://www.sancloud.co.uk/?page_id=254)
+
+* [Sancloud repositories on GitHub](https://github.com/SanCloudLtd)
+
+Description
+-----------
+
+This is the Yocto Project Board Support Package (BSP) layer for SanCloud devices.
+
+Currently supported hardware with corresponding Yocto Project MACHINE names:
+
+* `bbe`: Sancloud BeagleBone Enhanced (BBE)
+
+This BSP is layer is tested in two primary configurations:
+
+* Automotive Grade Linux (AGL)
+* Arago Distribution
+
+Additionally, this BSP layer should work with the distro-less configuration
+included in openembedded-core as well as the Poky distribution.
+
+Getting Started with AGL
+------------------------
+
+This BSP layer is included in the most recent stable branch of AGL, code-named
+Grumpy Guppy. AGL sources can be downloaded by following the
+[upstream instructions](https://wiki.automotivelinux.org/agl-distro/source-code).
+Once the AGL sources have been downloaded and you're in the top-level AGL
+directory, run the following commands to build the AGL Demo image for the
+Sancloud BBE:
+
+    source meta-agl/scripts/aglsetup.sh -m bbe agl-demo agl-devel
+    bitbake agl-demo-platform
+
+Getting started with Arago
+--------------------------
+
+A pre-integrated Arago Distribution repository is available at
+https://github.com/SanCloudLtd/sancloud-arago. Please follow the instructions
+in the README.md file in that repository to get started.
+
+Support
+-------
+
+Issues and Pull Requests for this BSP layer may be opened on our primary
+GitHub repository at https://github.com/SanCloudLtd/meta-sancloud.
+
+For further support enquiries please contact us via email to
+yocto@sancloud.co.uk.
