    # Provides methods to interact with subscribers of a YouTube resource.
    #
    # Resources with subscribers are: {Yt::Models::Account accounts}.
    #
    # Confusingly, YouTube API provides the +same+ endpoint to either
    # retrieve the channels that you are subscribed to or the channels
    # that are subscribed to you. The difference relies in the setting the
    # +mySubscribers+ parameter to true and in reading the information
    # from the +subscriberSnippet+ part, not the +snippet+ part.
    # @see https://developers.google.com/youtube/v3/docs/subscriptions/list
