Yeah. But as I said before, people installing Ferron on their servers don't need to use this demo. Oh, and people using this demo don't need to install Ferron on their servers.
I just added two notices to this demo:
> Note: After completing the demo, it's recommended to delete the subdomain you have just created to prevent security issues.
> This demo setup is optional and exists only to demonstrate automatic TLS functionality. You do not need to point any subdomain to demo servers for normal use of Ferron.
