 * `OSTREE_REPO` - path to your OSTree repository. Defaults to `$\{DEPLOY_DIR_IMAGE}/ostree_repo`
 * `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_COMMIT_BODY` - Message attached to OSTree commit. Empty by default. 
+* `OSTREE_COMMIT_SUBJECT` - Commit subject used by OSTree. Defaults to `Commit-id: ${IMAGE_NAME}`
+* `OSTREE_UPDATE_SUMMARY` - Set this to '1' to update summary of OSTree repository on each commit. '0' by default.
 * `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 zipped credentials file in https://github.com/advancedtelematic/aktualizr/blob/master/docs/credentials.adoc[the format accepted by garage-push].
 * `SOTA_DEPLOY_CREDENTIALS` - when set to '1' (default value), deploys credentials to the built image. Override it in `local.conf` to built a generic image that can be provisioned manually after the build.
