+### Websites are blocking headless browsers
+
+This is a well known issue. WRP has some provisions to work around it but same as ad blockers it's a cat and mouse game. The first and
+foremost recommendation is to change `User Agent` so that it doesn't say "headless". Add `-ua="my agent"` to override the default one.
+Obtain your regular desktop browser user agent and specify it as the flag. For example
+
+```shell
+$ wrp -ua="Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/119.0.0.0 Safari/537.36"
