-When using a regular expression, the setting will be activated if the name of the file being linted matches the given regular expression. For example, the above configurations will allow the import of `devDependencies` in files whose names include `test` or `spec`.
+When using a glob or regular expression, the setting will be activated if the name of the file being linted matches the given glob or regular expression. In addition, you can use an array to specify multiple globs or regular expressions:
