+Thunderbolt™ Support
+====================
+
+Introduction
+------------
+
+Thunderbolt™ is the brand name of a hardware interface developed by Intel that
+allows the connection of external peripherals to a computer.
+Versions 1 and 2 use the same connector as Mini DisplayPort (MDP), whereas
+version 3 uses USB Type-C.
+
+Build Requirements
+------------------
+
+For UEFI capsule support, you need to install libtbtfwu.
+* source:		https://github.com/01org/thunderbolt-software-user-space/tree/fwupdate
+
+If you don't want or need this functionality you can use the
+`--disable-thunderbolt` option.
