+# Logging
+
+confd logs all error message to stderr and everything else to stdout. You can control the types of messages that get printed by using the `-debug`, `-verbose`, and `-quiet` flags and corresponding configuration file settings. See the [Configuration Guide](https://github.com/kelseyhightower/confd/wiki/Configuration-Guide) for more details.
