+#### Extra Windows drivers
+Place all extra Windows drivers under infs directory.
+
+Please note that these drivers will be installed using
+dpinst.exe which does not support scanning sub directories.
+
+This requires all drivers to be present directly under the
+infs directory.
+
+These can include custom Windows drivers needed by certain
+hardware components to function, either becuase the drivers
+are not natively availble in Windows or would require extra
+optimization.
