+## Introduction
+
+The `meta-agl-devel` layer contains components that are being tested or
+still in development.
+The layer also contains software packages that Original Equipment
+Manufacturers (OEMs) need but are not included in the AGL software.
+
+## Sub-Layers
+
+The `meta-agl-devel` layer contains the following files and sub-layers:
+
+```
+.
+├── meta-agl-telemetry
+├── meta-audio-4a-framework
+├── meta-audio-soundmanager-framework
+├── meta-egvirt
+├── meta-gstrecorder-rcar-gen3
+├── meta-hmi-framework
+├── meta-oem-extra-libs
+├── README.md
+├── templates
+```
+
+The following list provides a summary of these sub-layers:
+
+* `meta-agl-telemetry`: Provides the smallest AGL image.
+  The image is designed to be used when a device requires restricted
+  scope of responsibilites (e.g. collecting vehicle telemetry).
+
+* `meta-audio-4a-framework`: A collection of recipes used for the
+  first integration of 4A (i.e. Advanced AGL Audio Architecture).
+
+  **NOTE:** Recipes from this layer will be integrated into the
+  `meta-agl` layer in the future.
+
+* `meta-audio-soundmanager-framework`: Supports the Soundmanager
+  Audio Framework features, which maps to the `agl-audio-soundmanager-framework`
+  AGL feature.
+
+* `meta-egvirt`: The AGL Virtualization Expert Group (EG-VIRT) layer.
+  This layer supports the design, test, implementation, and assessment
+  of virtualization technologies (e.g. containers, hypervisors, system
+  partitioners, and so forth) aimed at AGL ARMv8 and Intel platforms.
+
+* `meta-gstrecorder-rcar-gen3`: Supports streaming audio and video for
+  the Pro and Premier board kits (e.g.
+  [Renesas R-Car Starter Kit Pro Board](https://www.elinux.org/R-Car/Boards/M3SK)
+  and
+  [Renesas R-Car Starter Kit Premier Board](https://www.elinux.org/R-Car/Boards/H3SK)).
+
+* `meta-hmi-framework`: Provides AGL's Human Machine Interface (HMI) framework
+  through resource management consisting of sounds, windows, and input control.
+  For more information, see the
+  [HMI-Framework Page](https://wiki.automotivelinux.org/hmiframework) of the
+  AGL Wiki.
+
+* `meta-oem-extra-libs`: Provides libraries and software packages needed by
+  OEMs but not provided by the AGL software.
+
+* `templates`: Feature templates that support the `meta-agl-devel` layer.
+
+## Additional Sub-Layer Information
+
+This section provides additional information for the `meta-egvirt`,
+`meta-oem-extra-libs`, and `meta-hmi-framework` layers.
+
+### Virtualization Support
+
+The `meta-egvirt` layer enables virtualization support in AGL.
+The AGL Virtualization Expert (EG-VIRT) group is responsible
+for design and implementation of AGL virtualization solutions
+(.e.g the Virtualization platform architecture of AGL).
+You can read about EG-VERT's efforts on the
+"[Virtualization Expert Group's](https://wiki.automotivelinux.org/eg-virt)"
+page of the AGL wiki.
+
+Additionally, you can learn more about virtualization as it applies to AGL
+by reading
+"[The Automotive Grade Linux Software Defined Connected Car Architecture](https://www.automotivelinux.org/wp-content/uploads/sites/4/2018/06/agl_software_defined_car_jun18.pdf)"
+whitepaper.
+
+### OEM Extra Libraries
+
+The `meta-oem-extra-libs` layer provides additional software packages many OEMs need
+but are not part of the AGL source.
+Following is the list of packages this layer provides:
+
+ * boost
+ * fixesproto
+ * imagemagick
+ * iptables
+ * Xorg-macros
+ * zlib
+ * eglibc = glibc
+ * libcurl
+ * libgif
+ * libneon
+ * mongoose
+ * fuse
+ * protocol buffers
+ * bsdiff
+ * module-init-tools
+ * libcroco
+ * libtiff
+ * librsvg
+ * libpcap
+
+To add these packages to your library, you need to include the
+`agl-oem-extra-libs` AGL feature when you initialize your build
+environment using the `aglsetup.sh` script.
+
+For information on how to use the `aglsetup.sh` script to initialize
+your build environment, see the
+"[Initializing Your Build Environment](../../../../getting_started/en/dev/reference/image-workflow-initialize-build-environment.html)"
+section.
+
+Once you have included the AGL feature, you can build your image.
+
+### HMI Framework
+
+The `meta-hmi-framework` layer supports the Human-Machine Interface (HMI) Framework.
+The HMI-Framework is the User Interface (UI) to control the Infotainment System.
+Work continues to close the gap between the user experience of a smart phone
+and the Infotainment System in a vehicle, for example.
+
+You can find more out about HMI Framework progress on the
+"[HMI Framework](https://wiki.automotivelinux.org/hmiframework)" page on the AGL Wiki.
+
+To add HMI Framework support to your image, you need to include the
+`hmi-framework` AGL feature when you initialize your build
+environment using the `aglsetup.sh` script.
+
+For information on how to use the `aglsetup.sh` script to initialize
+your build environment, see the
+"[Initializing Your Build Environment](../../../../getting_started/en/dev/reference/image-workflow-initialize-build-environment.html)"
+section.
+
+Once you have included the AGL feature, you can build your image.
