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>>.

+1. Append the line below to `conf/local.conf` to disable the warning about supported operating systems:
++
+```
+SANITY_TESTED_DISTROS = ""

++
 ```
-SANITY_TESTED_DISTROS=""
+IMAGE_INSTALL_append = " dropbear "
 ```
 
-* 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:
++
 ```
 oe-selftest --run-tests updater
 ```
+
+For more information about oe-selftest, including details about how to run individual test modules or classes, please refer to the https://wiki.yoctoproject.org/wiki/Oe-selftest[Yocto Project wiki].
