 For all methods, you have `stealthy_headers` which makes `Fetcher` create and use real browser's headers then create a referer header as if this request came from Google's search of this URL's domain. It's enabled by default. You can also set the number of retries with the argument `retries` for all methods and this will make httpx retry requests if it failed for any reason. The default number of retries for all `Fetcher` methods is 3.
 
+> Hence: All headers generated by `stealthy_headers` argument can be overwritten by you through the `headers` argument
+
 You can route all traffic (HTTP and HTTPS) to a proxy for any of these methods in this format `http://username:password@localhost:8030`
 ```python
 >> page = Fetcher().get('https://httpbin.org/get', stealthy_headers=True, follow_redirects=True)
