+Plugin takes extra, non-mandatory arguments `paths`, `exclude`, `excludePattern` and `convertStrictErrorsToWarnings`. Args `paths` and
 `exclude` accept an array of relative or absolute paths that should be included (property `paths`)
 or excluded (property `exclude`). Arg `excludePattern` accepts an array of strings that will be
 matched with [minimatch](https://github.com/isaacs/minimatch). To add strict mode to files from
-ignored paths you can insert `//@ts-strict` comment.
+ignored paths you can insert `//@ts-strict` comment. Arg `convertStrictErrorsToWarnings` show errors from strict checking as warnings instead of errors. This allows for showing strict checking as a warning in codebases with a large amount
