The instruction —

> Set DISCOURSE\_HOSTNAME to [discourse.example.com](http://discourse.example.com), this means you want your Discourse available at [http://discourse.example.com/](http://discourse.example.com/). You’ll need to update the DNS A record for this domain with the IP address of your server.

I really think that you should specify it more clearly there.

And i changed [discourse.example.com](http://discourse.example.com) to [mydomain.com](http://mydomain.com), not just [example.com](http://example.com) …

It is working fine now…  
Thanks.
