# This is just a poorly written sample for reference only, please keep that in mind.

# This script requires the ZeroSeg library

# 
# The Youtube and Twitch functionality
# uses the official APIs and as such
# require a free dev API keys.
# These need to be filled in the
# respective variables (lines 30 and 59)
