 If you already have a Yocto-based project and you want to add atomic filesystem updates to it, you just need to do three things:
 
 1.  Clone the `meta-updater` layer and add it to your https://www.yoctoproject.org/docs/2.1/ref-manual/ref-manual.html#structure-build-conf-bblayers.conf[bblayers.conf].
-2.  Clone BSP integration layer (meta-updater-$\{PLATFORM}, e.g. https://github.com/advancedtelematic/meta-updater-raspberrypi[meta-updater-raspberrypi]) and add it to your conf/bblayers.conf. If your board isn't supported yet, you could write a BSP integration for it yourself. See the <<Adding support for your board>> section for the details.
-3.  Set up your https://www.yoctoproject.org/docs/2.1/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 third party distro configuration, you can add 'INHERIT += " sota"' to it, thus combining 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 (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>>.

-* Run oe-selftest:
+3. To be able to build an image for the grub tests, you will need to install https://github.com/tianocore/tianocore.github.io/wiki/OVMF[TianoCore's ovmf] package on your host system. On Debian-like systems, you can do so with this command:
++
+```
+sudo apt install ovmf

+4. Run oe-selftest:

 ```
