+Update image
+------------
+
+After the build finished, there will be an update image called
+u-boot.update. This can either be used in the DFU mode (which isn't
+supported yet) or encapsulated in an EFI UpdateCapsule.
+
+To build the capsule use the following command
+
+ $ tools/mkeficapsule -f u-boot.update -i 1 UpdateUboot
+
+Afterward you can copy this file to your ESP into the /EFI/UpdateCapsule/
+folder. On the next EFI boot this will automatically update your
+bootloader.
