-This is the default nginx configuration for gancio, please modify at least the **server_name** and **ssl_certificate**'s path.  
-Note that this does not include a cache configuration and that gancio does
-not use a cache control at all, if you can help with this task you're
-welcome.
+This is the default nginx configuration for gancio, it does not include **HTTPS** setup but you can easily use [certbot](https://certbot.eff.org/) for that.
