 This file summarizes notable changes introduced in aktualizr version. It roughly follows the guidelines from [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
 
-Our versioning scheme is `YEAR.N` where `N` is incremented whenever a new release is deemed necessary. Thus it does not exactly map to months of the year.

-3.  Set up your https://www.yoctoproject.org/docs/2.6/ref-manual/ref-manual.html#var-DISTRO[distro]. If you are using "poky", the default distro in Yocto, you can change it in your conf/local.conf to "poky-sota". Alternatively, if you are using your own or a third-party distro configuration, you can add `INHERIT += " sota"` to it, thus combining the capabilities of your distro with meta-updater features.

 You can then build your image as usual, with bitbake. After building the root file system, bitbake will then create an https://ostree.readthedocs.io/en/latest/manual/adapting-existing/[OSTree-enabled version] of it, commit it to your local OSTree repo, and push it to OTA Connect. Additionally, a live disk image will be created (normally named `$\{IMAGE_NAME}.wic` e.g. `core-image-minimal-raspberrypi3.wic`).

+= Use of Virtual Secondaries
+ifdef::env-github[]

+Virtual secondaries can be used as a way to update a configuration file on the primary (where the primary is a standard OSTree image running an aktualizr). You can do this in two parts:
+
+* First you need a virtual secondary configured that can be used to update a configuration file.
+* Afterwards you can integrate it into your Yocto build.
+
+
+
+== Creating a Virtual Secondary
+
+. You can create a virtual secondary to run locally by following the steps on how to xref:simulate-device-basic.adoc[simulate a device without building a disk image].
++
+You can use the provided `.deb` releases mentioned and the `virtualsec.json` file, which you can edit to suit your needs: such as removing one of the two entries and setting the paths and names to whatever you prefer.
+. Afterwards, you will be able to download the arbitrary files to the location specified in the `firmware_path` variable.
+. Next, you can upload the files for the virtual secondary. To do so, go to the *Software versions* tab in the https://connect.ota.here.com[OTA Connect Portal] and click *Add Software*. You should make sure the *ECU Types* field matches the value specified in the `ecu_hardware_id` variable of the `virtualsec.json` file.
++
+NOTE: `ecu_hardware_id` must be unique per each file type that you'll like to deliver, otherwise an update of one of them will rewrite the others.
+
+
+== Updating via Virtual Secondaries
+
+To issue the update perform the following steps:
+
+. Go to your *Devices* tab and find your primary. (You can run `aktualizr-info` locally to get the name of the primary if you don't know it.)
+. Afterwards, select your virtual secondary and the file you uploaded to the *Software versions* tab.
+. After your selection, the primary will begin to download the file.
++
+For future reference, you can use the *Campaigns* tab to send updates to multiple devices simultaneously.
+
+
+
+== Integrating Virtual Secondaries into Yocto
+
+You can use the files in the repository https://github.com/advancedtelematic/meta-updater/blob/master/recipes-sota/config/aktualizr-virtualsec.bb[here] as an example to get the virtual secondaries to work in Yocto. You can use the files directly or you can copy them to one of your layers and modify them according to your needs.
