 ## Potential use cases
 
 ### RDP File Signing
-I've used the code signing certificate to sign .rdp files in order to avoid the certificate warning. 
+Use the code signing certificate generated with `New-CodeSigningCert.ps1` to sign .rdp files in order to avoid the certificate warning. 
 - Create the .rdp file with all of the settings you'll need
 - Generate a certificate using `New-CodeSigningCert`
 - Get the thumbprint of the certificate you'll use to sign the .rdp file with `Get-ChildItem -Path Cert:CurrentUser\My`
 - Run `rdpsign.exe /sha1 <thumbprint> C:\Path\To\workstation.rdp`
 - Configure group policy to trust the certificate
 - `Import-Module .\Set-RDPTrustedPublishers.psm1`
 - `Set-RDPTrustedPublishers -SHA1Thumb <thumbprint> -Verbose`
+- As an alternative, you can manually configure the GPO if desired. Reference: https://blog.superautomation.co.uk/2020/10/rdp-file-signing.html
