# Unless the final configuration (`matrix_appservice_irc_configuration`) contains an `ircService` definition,

# This is a safety check to ensure we fail earlier and in a nicer way.

      Your Appservice IRC configuration is incomplete (lacking an `ircService.servers` configuration).
      You need to define one or more servers by either using `matrix_appservice_irc_ircService_servers`
      or by extending the base configuration with additional configuration in `matrix_appservice_irc_configuration_extension_yaml`.
      Overriding the whole bridge's configuration (`matrix_appservice_irc_configuration`) is yet another possibility.

      Your configuration contains a variable, which now has a different name.
      Please change your configuration to rename the variable (`{{ item.old }}` -> `{{ item.new }}`).
