 Aims for compatibility with [WebTorrent](https://github.com/webtorrent)
 clients, with some exceptions:
 
-  * Only runs over TLS (wss protocol)
   * Doesn't track of the number of torrent downloads (0 is always sent). 
   * Doesn't allow full scrapes, i.e. of all registered info hashes

-Please see `aquatic_http` TLS section above.
+To run over TLS, a pkcs12 file (`.pkx`) is needed. It can be generated from
+Let's Encrypt certificates as follows, assuming you are in the directory where
+they are stored:
+
+```sh
+openssl pkcs12 -export -out identity.pfx -inkey privkey.pem -in cert.pem -certfile fullchain.pem
+```
+
+Enter a password when prompted. Then move `identity.pfx` somewhere suitable,
+and enter the path into the tracker configuration field `tls_pkcs12_path`. Set
+the password in the field `tls_pkcs12_password` and set `use_tls` to true.

+#### TLS: glommio version

+The glommio version only runs over TLS. For setup instructions, please see
