+* Troubleshooting
+
+** Debugging HTTP responses
+
+It might be useful to see the full HTTP response while developing a
+new media type format or ~plz-media-type~ is failing to parse a
+response of an HTTP request. When the ~plz-media-type-debug-p~ custom
+variable is set to a non-nil value, each chunk of the HTTP response is
+written to the buffer configured by the
+~plz-media-type-debug-response-buffer~ custom variable as it
+arrives. The buffer is cleared on each new request, unless
+~plz-media-type-debug-erase-buffer-p~ is set to a non-nil value.
