+Running Shell Commands
+^^^^^^^^^^^^^^^^^^^^^^
+
+Normally, arbitrary U-Boot command execution is not enabled. This is so
+fastboot can be used to update systems using verified boot. However, such
+functionality can be useful for production or when verified boot is not in use.
+Enable ``CONFIG_FASTBOOT_OEM_RUN`` to use this functionality. This will enable
+``oem run`` command, which can be used with the fastboot client. For example,
+to print "Hello at 115200 baud" (or whatever ``CONFIG_BAUDRATE`` is), run::
+
+    $ fastboot oem run:'echo Hello at $baudrate baud'
+
+You can run any command you would normally run on the U-Boot command line,
+including multiple commands (using e.g. ``;`` or ``&&``) and control structures
+(``if``, ``while``, etc.). The exit code of ``fastboot`` will reflect the exit
+code of the command you ran.
