unified().use(remarkLintFinalDefinition)

Warn when definitions are used in the document instead of at the end.

Compatibility

Projects maintained by the unified collective are compatible with maintained versions of Node.js.

When we cut a new major release, we drop support for unmaintained versions of Node. This means we try to keep the current release line, remark-lint-final-definition@4, compatible with Node.js 16.
