-## 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.
