+	  This enables SCIF Driver support for the Intel Many Integrated
+	  Core (MIC) family of PCIe form factor coprocessor devices that
+	  run a 64 bit Linux OS. The Symmetric Communication Interface
+	  (SCIF (pronounced as skiff)) is a low level communications API
+	  across PCIe currently implemented for MIC.
+
+	  If you are building a host kernel with an Intel MIC device then
+	  say M (recommended) or Y, else say N. If unsure say N.
+
+	  More information about the Intel MIC family as well as the Linux
+	  OS and tools for MIC to use with this driver are available from
+	  <http://software.intel.com/en-us/mic-developer>.
