Additionally, you can reload the configuration file by sending the USR1
signal to the Helix process on Unix operating systems, such as by using the command `pkill -USR1 hx`.
Finally, you can have a `config.toml` local to a project by putting it under a `.helix` directory in your repository.
Its settings will be merged with the configuration directory `config.toml` and the built-in configuration.
