+
+## Introduction
+
+The `meta-agl-demo` layer is the reference user interface layer for the DEMO
+platform of Automotive Grade Linux (AGL).
+The layer provides a reference platform and applications.
+The BitBake target name for the DEMO platform is `agl-demo-platform`, which is
+the full DEMO platform image.
+
+## Layer Dependencies
+
+This section describes dependencies for the `meta-agl-demo` layer.

+## Packagegroups
+
+AGL DEMO Platform's
+[packagegroups](https://www.yoctoproject.org/docs/3.1.2/dev-manual/dev-manual.html#usingpoky-extend-customimage-customtasks)
+consist of the following:
+
+### packagegroup-agl-demo-platform
+
+This packagegroup is used for generating the `agl-demo-platform` image,
+which is the full image for the AGL distributions IVI profile.
+You can see the recipe (i.e. `agl-demo-platform.bb`) that installs
+the `packagegroup-agl-demo-platform` packagegroup
+[here](https://git.automotivelinux.org/AGL/meta-agl-demo/tree/recipes-platform/images/agl-demo-platform.bb).
+
+As meta-agl's design of packagegroups, the `agl-demo-platform.bb` recipe installs
+only `packagegroup-agl-demo-platform` and the packages of the DEMO applications.
+
+``agl-demo-platform`` contains the following three packagegroups:
+
+  * `packagegroup-agl-image-minimal`
+  * `packagegroup-agl-image-ivi`
+  * `packagegroup-agl-demo-platform`
+
+### packagegroup-agl-appfw*
+
+These packagegroups contain packages for the AGL distribution's
+Application Framework.
+Subsystem should maintain `packagegroup-agl-appfw-[subsystem].bb`, which
+should hold sufficient packages for the Application Framework.
+
+Subsystems also can maintain their own packagegroups using appropriate
+`recipes-*/`.
+For example, Qt5 has two packagegroups in `meta-agl-demo`:
+`packagegroup-agl-appfw-native-qt5` and `packagegroup-agl-demo-qt-examples`,
+which are under `recipes-qt/`.
+
+The `packagegroup-agl-appfw-native-qt5` is included by
+`packagegroup-agl-appfw-native` because Qt5 belongs to native application
+framework of AGL Distro.
+
+Because the `packagegroup-agl-demo-qt-examples` is not mandatory for
+the AGL Application Framework and the AGL DEMO, the packagegroup is added
+to the layer's `local.conf` file only when needed.
