# Configuration options

These options can be set in the configuration file, `~/.jupyter/jupyter_qtconsole_config.py`, or at the command line when you start Qt console.

You may enter `jupyter qtconsole --help-all` to get information about all available configuration options.

## Options

ConnectionFileMixin.connection_fileUnicode

  Default: `''`

  JSON file in which to store connection info [default: kernel-<pid>.json]
