 ## Tips
 
-* `hey` does not randomize the request payload, there's nothing saying you cannot call it a bunch with different payloads, though.
-* `hey` defaults Content-Type to "text/html".
-* `hey` requires parameters to be in a certain order. For example, if you don't use the order above, the post body may be empty.
