To customize this configuration, you have two options: create a custom
configuration file in this directory, or specify a path to a configuration file
explicitly when starting Aphlict.

To create a custom configuration file, copy `aphlict.default.json` in this
directory and rename it `aphlict.custom.json`. If this file exists, it will
be read by default.

To specify a path when starting Aphlict, use the `--config` flag:

  phabricator/ $ ./bin/aphlict start --config path/to/config.json

Specifying a configuration file explicitly overrides default configuration.

"Notifications User Guide: Setup and Configuration" in the documentation.
