+Running barebox
+---------------
+
+Building the barebox image for this target is covered by the ``efi_defconfig``
+
+BIOS should be configured as follow:
+
+  * When you turn on the computer, the BIOS is immediately activated. Pressing
+    the <Del> key immediately allows you to enter the BIOS Setup utility. If you are
+    a little bit late pressing the <Del> key, POST (Power On Self Test) will
+    continue with its test routines, thus preventing you from invoking the Setup.
+    In this case restart the system by pressing the ”Reset” button or simultaneously
+    pressing the <Ctrl>, <Alt> and <Delete> keys. You can also restart by turning the
+    system Off and back On again.
+  * Reset BIOS settings. With this step we wont to make sure BIOS has defined common state to avoid
+    undocumented issues. Switch to "Save & Exit" tab, choice "Restore Defaults"
+    and press Enter. Answer "Yes" and press Enter again. Then choice "Save Changes and Exit"
+    and press Enter.
+  * Enable UEFI support. Switch to "Boot" tab. Choice "Boot mode select" and set it to "UEFI".
+    Switch in the "Save & Exit" tab to "Save Changes and Exit" and press Enter.
+
+To make network work in barebox you will need to prepare efi binary network drivers and put them in to
+"network-drivers" directory.
+
+To continue please proceed with barebox :ref:`barebox_on_uefi` documentation.
