 Although we have used U-Boot so far, other boot loaders can be configured work with OSTree as well.
 
+Your images will also need network connectivity to be able to reach an actual OTA backend. Our 'poky-sota' distribution does not mandate or install a default network manager but our supported platforms use the `virtual/network-configuration` recipe, which can be used as a starting example.
