+.SYNOPSIS
+Signs NuGet and Symbol packages using a smart card certificate.
+
+.DESCRIPTION
+Signs NuGet packages (*.nupkg) and their corresponding symbol packages (*.snupkg) using a hardware-based certificate. 
+The script processes the contents of two required zip files ('Nuget Packages.zip' and 'Symbols Packages.zip'), 
+signs all assemblies within the NuGet packages, repacks them, and then signs both the NuGet and Symbol packages.
+
+How to use:
+1. Create a release folder on your machine e.g. ../releases/1.12
+2. Download the build assets "Nuget Packages.zip" and "Symbols Packages.zip" from the latest SDK build action 
+   to the newly created folder.
+3. Start a Powershell terminal, and load the script by running the following command:
+   > . \.Yubico.NET.SDK\build\sign.ps1
+4. The script can be invoked by following the examples below.
+
+.PARAMETER Thumbprint
+The thumbprint of the signing certificate stored on the smart card.
+
+.PARAMETER WorkingDirectory
+The directory containing the zip files and where the signing process will take place.
+
+.PARAMETER SignToolPath
+Optional. Path to signtool.exe. Defaults to "signtool.exe" (expects it in PATH).
+
+.PARAMETER NuGetPath
+Optional. Path to nuget.exe. Defaults to "nuget.exe" (expects it in PATH).
+
+.PARAMETER TimestampServer
+Optional. URL of the timestamp server. Defaults to "http://timestamp.digicert.com".
+
+.PARAMETER NuGetPackagesZip
+Optional. Name of the NuGet packages zip file. Defaults to "Nuget Packages.zip".
+
+.PARAMETER SymbolsPackagesZip
+Optional. Name of the symbols packages zip file. Defaults to "Symbols Packages.zip".
+
+.PARAMETER CleanWorkingDirectory
+Optional switch. If specified, cleans the working directories before processing.
+
+.EXAMPLE
+Invoke-NuGetPackageSigning -Thumbprint "0123456789ABCDEF" -WorkingDirectory "C:\Signing"
+
+.EXAMPLE
+Invoke-NuGetPackageSigning -Thumbprint "0123456789ABCDEF" -WorkingDirectory "C:\Signing" -CleanWorkingDirectory -NuGetPath "C:\Tools\nuget.exe"
+
+.NOTES
+Requires:
+- A smart card with the signing certificate
+- signtool.exe (Windows SDK)
+- nuget.exe
+- PowerShell 5.1 or later
