 ====== meta-updater ======
+Yocto/OpenEmbedded layer [[https://github.com/advancedtelematic/meta-updater|meta-updater]] provides libostree and Aktualizr in Automotive Grade Linux (AGL). [[https://github.com/advancedtelematic/aktualizr|Aktualizr]] is a C++ reference implementation of SOTA OTA update client integrated with libostree.
+====== Demo ======
+Although the straight-forward way for doing [[https://docs.atsgarage.com/quickstarts/automotive-grade-linux.html|Software OTA updates in AGL is through ATS Garage]], it is also possible to use directly OSTree built with the **agl-sota** feature and **meta-updater**.
+Required hardware for setting up a demo Raspberry Pi 3:
+  * Raspberry Pi 3
+  * microSD card
+  * Build machine
+  * Router and a couple of Ethernet cables
+For example, the following procedure performs an update of AGL image on Raspberry Pi and adds the simple text editor **nano**:
+  * Built AGL image for Raspberry Pi 3 and boot it on the board.
+  * Add the following line to conf/local.conf to add **nano** and rebuild the image:
+  IMAGE_INSTALL_append = " nano "
+  * On the host, go to directory:
+  cd tmp/deploy/images/raspberrypi3/ostree_repo
+  * On the host, start a simple web server:
+  python -m SimpleHTTPServer 8000
+  * On the Raspberry Pi 3, configure OSTree remote:
+  ostree remote add --no-gpg-verify agl http://<host_ip>:8000
+  * On the Raspberry Pi 3, check for new updates:
+  ostree pull agl raspberrypi3
+  * On the Raspberry Pi 3, deploy an update:
+  ostree admin deploy agl:raspberrypi3
+  * On the Raspberry Pi 3, reboot the system to apply the update:
+  systemctl reboot
+  * On the Raspberry Pi 3, verify that **nano** has been successfully provided with the update.
