   === File output
  -By default, log files are written to `spring.log` in your `temp` directory and rotate at
  -10 Mb. You can easily customize the output folder by setting the `logging.path` property
  -(for example in your `application.properties`). It is also possible to change the filename
  -using a `logging.file` property. Note that if `logging.file` is used, then setting `logging.path` has no effect.
  +By default, Spring Boot will only log to the console and will not write log files. If you
  +want to write log files in addition to the console output you need to set the
  +`logging.file` and/or `logging.path` properties (for example in your
  +`application.properties`). Log files will rotate when they reach 10 Mb.
   
   As with console output, `ERROR`, `WARN` and `INFO` level messages are logged by default.

  +The following table shows how the `logging.*` properties can be used together:

  http://logback.qos.ch/[Logback].
  In each case there is console output and file output (rotating, 10 Mb file size).
  
  By default, If you use the '`Starter POMs`', Logback will be used for logging. Appropriate
  Logback routing is also included to ensure that dependent libraries that use
