+    You can use BASH patterns for including and excluding files (only files).
+    Patterns are case-sensitive and have to use slashes as a path separators.
+    A pattern to exclude from processing starts with "!".
+
     Parsing mode can be "cjson" or "json5" to enable other flags automatically.
     If no files or directories are specified, stdin will be parsed. Environments
     for JSON schema validation are "json-schema-draft-04", "json-schema-draft-06"
