# Installation Instructions
# ============================================================================
# Run the script with the plugin url as the parameter in a PowerShell session:
# PS C:\Users\Administrator> .\install-vdvs.ps1 <vdvs-download-url>
#
# The -Force parameter suppresses any confirmation prompt and performs an
# affirmative action. For example, supplying -Force during installation will
# uninstall any previous installation of the plugin, without confirmation.
# Supplying -Force during uninstallation suppresses the confirmation prompt
# and uninstalls the plugin.
# ============================================================================
