+========================================================================
+    FileLocksmithGUI Project Overview
+========================================================================
+
+This project demonstrates how to get started writing WinUI3 apps directly
+with standard C++, using the Windows App SDK and C++/WinRT packages and
+XAML compiler support to generate implementation headers from interface
+(IDL) files. These headers can then be used to implement the local
+Windows Runtime classes referenced in the app's XAML pages.
+
+Steps:
+1. Create an interface (IDL) file to define any local Windows Runtime
+    classes referenced in the app's XAML pages.
+2. Build the project once to generate 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.
+
