+## Example Web Server Config (apache)  
+
+All nonexisting URLs are being reverse proxied to a HellPot instance on localhost, which is set to catchall. Traffic served by HellPot is rate limited to 5 KiB/s.
+
+* Create your normal robots.txt and usual content. Also create the fake Errordocument directory and files (files can be empty). In the example, the directory is "/content/"
+* A request on a URL with an existing handler (f.e. a file) will be handled by apache
+* Requests on nonexisting URLs cause a HTTP Error 404, which content is served by HellPot
+* URLs under the "/.well-known/" suffix are excluded.
