The [check-spelling](https://github.com/marketplace/actions/check-spelling) action will run in response to your **push** -- it doesn't require an open pull request.

+  File paths are Perl 5 Regular Expressions - you can [test](
+https://www.regexplanet.com/advanced/perl/) yours before committing to verify it will match your files.
+
+  `^` refers to the file's path from the root of the repository, so `^README\.md$` would exclude [README.md](

+========================================================================
+    C++/WinRT ScratchWinRTClient Project Overview
+========================================================================
+
+This project demonstrates how to get started consuming Windows Runtime 
+classes directly from standard C++, using platform projection headers
+generated from Windows SDK metadata files.
+
+Steps to generate and consume SDK platform projection:
+1. Build project initally to generate platform projection headers into
+    your Generated Files folder.
+2. Include a projection namespace header in your pch.h, such as 
+    <winrt/Windows.Foundation.h>.
+3. Consume winrt namespace and any Windows Runtime namespaces, such as 
+    winrt::Windows::Foundation, from source code.
+4. Initialize apartment via init_apartment() and consume winrt classes.
+
+Steps to generate and consume a projection from third party metadata:
+1. Add a WinMD reference by right-clicking the References project node
+    and selecting "Add Reference...".  In the Add References dialog, 
+    browse to the component WinMD you want to consume and add it.
+2. Build the project once to generate projection headers for the 
+    referenced WinMD file under the "Generated Files" subfolder.
+3. As above, include projection headers in pch or source code 
+    to consume projected Windows Runtime classes.

+========================================================================
+    C++/WinRT ScratchWinRTServer Project Overview
+========================================================================
+
+This project demonstrates how to get started consuming Windows Runtime 
+classes directly from standard C++, using platform projection headers
+generated from Windows SDK metadata files.
+
+Steps to generate and consume SDK platform projection:
+1. Build project initally to generate platform projection headers into
+    your Generated Files folder.
+2. Include a projection namespace header in your pch.h, such as 
+    <winrt/Windows.Foundation.h>.
+3. Consume winrt namespace and any Windows Runtime namespaces, such as 
+    winrt::Windows::Foundation, from source code.
+4. Initialize apartment via init_apartment() and consume winrt classes.
+
+Steps to generate and consume a projection from third party metadata:
+1. Add a WinMD reference by right-clicking the References project node
+    and selecting "Add Reference...".  In the Add References dialog, 
+    browse to the component WinMD you want to consume and add it.
+2. Build the project once to generate projection headers for the 
+    referenced WinMD file under the "Generated Files" subfolder.
+3. As above, include projection headers in pch or source code 
+    to consume projected Windows Runtime classes.
+
