Is the config in overrides merged into the main config?

[haocheng6]

I read How do overrides work? in the documentation, but it is not clear whether the config in overrides completely replaces the regular config or they will get merged into the regular config.

A similar issue was also brought up in the eslint website repository. (See #504.)

Thank you. :)

they will be merged.
