+      JJ is a command line utility that provides a fast and simple way to retrieve
+      or update values from JSON documents. It's powered by GJSON and SJSON under the hood.
+      It's fast because it avoids parsing irrelevant sections of json, skipping over values
+      that do not apply, and aborts as soon as the target value has been found or updated.
