+========================================================================
+    DYNAMIC LINK LIBRARY : Twine.FirmwareUpdateLib Project Overview
+========================================================================
+
+AppWizard has created this Twine.FirmwareUpdateLib DLL for you.  
+
+This file contains a summary of what you will find in each of the files that
+make up your Twine.FirmwareUpdateLib application.
+
+Twine.FirmwareUpdateLib.vcxproj
+    This is the main project file for VC++ projects generated using an Application Wizard. 
+    It contains information about the version of Visual C++ that generated the file, and 
+    information about the platforms, configurations, and project features selected with the
+    Application Wizard.
+
+Twine.FirmwareUpdateLib.vcxproj.filters
+    This is the filters file for VC++ projects generated using an Application Wizard. 
+    It contains information about the association between the files in your project 
+    and the filters. This association is used in the IDE to show grouping of files with
+    similar extensions under a specific node (for e.g. ".cpp" files are associated with the
+    "Source Files" filter).
+
+Twine.FirmwareUpdateLib.cpp
+    This is the main DLL source file.
+
+Twine.FirmwareUpdateLib.h
+    This file contains a class declaration.
+
+AssemblyInfo.cpp
+	Contains custom attributes for modifying assembly metadata.
+
+/////////////////////////////////////////////////////////////////////////////
+Other notes:
+
+AppWizard uses "TODO:" to indicate parts of the source code you
+should add to or customize.
