Thanks for the PR.

There are some mistakes though in it. Mainly in descriptions.

Thanks for the fixes.

I should point out though that I find it quite annoying to receive fixes through a force-push. It means I can't see a diff of the changes, so I essentially need to re-review everything again.

Also, I wonder is there any reason for creating a separate directory for this one JSON file? If no, then I would just place it into the root dir of the repository.

Also, we should add a few words about the existence of this schema file to README. Or maybe just include the $schema entry inside the config file example in there.

Thanks.
