+    .DESCRIPTION
+        Helper script to format all header and source files in the repository.
+
+        By default, the script will recursively search under the repo root for
+        files to format.  Users can give explicit parameters indicating how the
+        search should include and exclude filetypes.
+
+        If users don't want the search functionality, they can instead provide
+        an explicit list of files to format.
+
+    .PARAMETER RepoRoot
+        Full path to the root of the repository which is the target of the search.
+        Will default to the root of the current working directory.
+
+    .PARAMETER Include
+        Array of filetype extensions to target for formatting.
+        By default, targets standard extensions for header and source files.
+        Follows the same rules as the -Include parameter for Get-ChildItem.
+
+    .PARAMETER Exclude
+        Array of filetype extensions to exclude from formatting.
+        By default, excludes generated XAML files.
+        Follows the same rules as the -Exclude paramter for Get-ChildItem.
+
+    .PARAMETER Files
+        Array of files to format. The script will exit if one of the provided
+        filepaths does not exist.
+
+    .EXAMPLE
+        .\clang-format-all.ps1
+
+        Formats all header and source files under the repository root.
+
+    .EXAMPLE
+        .\clang-format-all.ps1 -RepoRoot 'S:\repos\calculator' -Include '*.h', '*.cpp' -Exclude '*.g.*'
+
+        Formats all *.h and *.cpp files under 'S:\repos\calculator', excluding files with an extension
+        like *.g.*
+
+    .EXAMPLE
+        .\clang-format-all.ps1 -File 'S:\repos\calculator\src\CalcViewModel\UnitConverterViewModel.h', 'S:\repos\calculator\src\CalcViewModel\MemoryItemViewModel.cpp'
+
+        Formats the specified files.
