+
+#### Input for fuzzing templates:
+
+Current fuzzing support is limited to URLs with with query parameters, so any urls with no query parameters will be simply ignored.
+
+```bash
+$ cat fuzz_endpoints.txt
+
+http://127.0.0.1:8082/info?name=test&another=value&random=data
+http://127.0.0.1:8082/redirect?redirect_url=/info?name=redirected_from_url

+
+> *You can use [katana](https://github.com/projectdiscovery/katana) with query url filter (`-f qurl`) to get list of endpoints to run with url fuzzing templates*
