1. Download the checksum file from the PowerShell GitHub releases page.
2. Use the following command to verify the checksum (replace <checksum-file> and <downloaded-file> with the appropriate file names):

   shasum -a 256 -c <checksum-file>

This will verify that the downloaded file matches the checksum provided by the PowerShell team.
