+                               looks for cspell.json in the current directory.
+
+  -v, --verbose                Display more information about the files being
+                               checked and the configuration.
+
+  --locale <locale>            Set language locales. i.e. "en,fr" for English
+                               and French, or "en-GB" for British English.
+
+  --language-id <language>     Force programming language for unknown
