+Whether hide spinner and other interactive things. This can be also controlled with `--no-tty` option for `lefthook run` command.

 ### `extends`
 
 You can extend your config with another one YAML file. Its content will be merged. Extends for `lefthook.yml`, `lefthook-local.yml`, and [`remote`](#remote) configs are handled separately, so you can have different extends in these files.
