+#A script that checks multiple youtube and bitchute channels for new videos to download via youtube-dl
+#This script works considerably faster than just giving youtube-dl a channel URI.
+#The YouTube implementation now uses a YoutubeData API v3 key to work more reliably.
+#Either insert this key in plain text below at the variable "APIKEY" or do it via ENV vars or a password manager
+#Since bitchute still doesn't have an API I'm using lynx to emulate a user.
+#This can be limit the number of recent videos available. For a whole download of bitchute channels consider other methods first.
