+## Sending JSON requests from external files
+
+If you have a JSON file that represents the body of your request, you can use the `json` option.
+
+Strest will read the JSON file you have specified and add it to the body of the request, you won't even need to worry about the Content-Type header, Strest will take care of that for you.
