Is your feature request related to a problem? Please describe.
Description in npmjs describes Supported options in config file can be the same with cli options. for the Config section, but it is not accurate as the parameters/flags in the cli are kebab-case but the accepted values for the config is camelCase. I spent over 3 hours trying to figure this out.

Describe the solution you'd like
Clarify that the config file accepts camelCase for the options, not kebab-case.
