# Script to assist with PVEDiscordDark development
#
# By default serves HTTP on port 3000, any *.js request gets the JS script, any *.css request gets the CSS file and any image request gets corresponding image
# Meant to be used with the "Requestly" browser extension to redirect PVEDD requests from PVE server to localhost:3000
