+========================================================================
+    C++/WinRT WebViewBridgeComponent Project Overview
+========================================================================
+
+This project demonstrates how to get started authoring Windows Runtime 
+classes directly with standard C++, using the C++/WinRT SDK component 
+to generate implementation headers from interface (IDL) files.  The
+generated Windows Runtime component binary and WinMD files should then
+be bundled with the Universal Windows Platform (UWP) app consuming them.
+
+Steps:
+1. Create an interface (IDL) file to define your Windows Runtime class, 
+    its default interface, and any other interfaces it implements.
+2. Build the project once to generate module.g.cpp, module.h.cpp, and
+    implementation templates under the "Generated Files" folder, as 
+    well as skeleton class definitions under "Generated Files\sources".  
+3. Use the skeleton class definitions for reference to implement your
+    Windows Runtime classes.
+
