API

This package exports no identifiers. The default export is remarkLintNoUnusedDefinitions.

unified().use(remarkLintNoUnusedDefinitions[, config])

This rule supports standard configuration that all remark lint rules accept (such as false to turn it off or [1, options] to configure it).
There are no options.

No messages.

not-ok.md

In

```markdown ```

Out

1:1-1:27: Found unused definition
