+This layer enables over-the-air updates (OTA) with https://github.com/ostreedev/ostree[OSTree] and https://github.com/advancedtelematic/aktualizr[Aktualizr].
 
 https://github.com/ostreedev/ostree[OSTree] is a tool for atomic full file system upgrades with rollback capability. OSTree has several advantages over traditional dual-bank systems, but the most important one is that it minimizes network bandwidth and data storage footprint by sharing files with the same contents across file system deployments.

 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 (optionally) push it to a remote server. Additionally, a live disk image will be created (normally named $\{IMAGE_NAME}.-sdimg-ota e.g. core-image-raspberrypi3.rpi-sdimg-ota). You can control this behaviour through <<variables in your local.conf,OSTree-related variables in your local.conf>>.

-* OSTREE_REPO - path to your OSTree repository. Defaults to "$\{DEPLOY_DIR_IMAGE}/ostree_repo"
-* OSTREE_BRANCHNAME - the branch your rootfs will be committed to. Defaults to "ota"
-* OSTREE_OSNAME - OS deployment name on your target device. For more information about deployments and osnames see the https://ostree.readthedocs.io/en/latest/manual/deployment/[OSTree documentation]. Defaults to "poky".
-* OSTREE_INITRAMFS_IMAGE - initramfs/initrd image that is used as a proxy while booting into OSTree deployment. Do not change this setting unless you are sure that your initramfs can serve as such a proxy.
-* SOTA_PACKED_CREDENTIALS - when set, your ostree commit will be pushed to a remote repo as a bitbake step. This should be the path to a JSON credentials file in https://github.com/advancedtelematic/sota-tools#credentials[the format accepted by garage-push].

+* `SOTA_CLIENT_PROV` - which provisioning method to use. Valid options are https://github.com/advancedtelematic/aktualizr/blob/master/docs/automatic-provisioning.adoc[`aktualizr-auto-prov`], https://github.com/advancedtelematic/aktualizr/blob/master/docs/implicit-provisioning.adoc[`aktualizr-implicit-prov`], and `aktualizr-hsm-test-prov`. The default is `aktualizr-auto-prov`. This can also be set to an empty string to avoid using a provisioning recipe.
+* `SOTA_CLIENT_FEATURES` - extensions to aktualizr. Multiple can be specified if separated by spaces. Valid options are `hsm` (to build with HSM support) and `secondary-example` (to install an example https://github.com/advancedtelematic/aktualizr/blob/master/docs/legacysecondary.adoc[legacy secondary interface] in the image).
+* `SOTA_LEGACY_SECONDARY_INTERFACE` - path to a legacy secondary interface installed on the device. To use the example interface from the Aktualizr repo, use `/usr/bin/example-interface` and make sure `SOTA_CLIENT_FEATURES = "secondary-example"`.
+* `SOTA_SECONDARY_ECUS` - a list of paths separated by spaces of JSON configuration files for virtual secondaries on the host. These will be installed into `/var/sota/ecus` on the device.
+* `SOTA_VIRTUAL_SECONDARIES` - a list of paths separated by spaces of JSON configuration files for virtual secondaries installed on the device. If `SOTA_SECONDARY_ECUS` is used to install them, then you can expect them to be installed in `/var/sota/ecus`.
