+
+- Output a schema of JSON or JSON Lines data from stdin to stdout (useful for grep):
+
+`cat {{file.json}} | jello -s`
+

+
+- Output the first element in JSON or JSON-Lines data from stdin to stdout:
+
+`cat {{file.json}} | jello _[0]`
+
+- Output the value of a given key of each element in JSON or JSON-Lines data from stdin to stdout:
+
+`cat {{file.json}} | jello '[i.{{key_name}} for i in _]'`
+
+- Output the value of multiple keys as a new JSON object (assuming the input JSON has the keys `key_name` and `other_key_name`):
