In this article, we are going to install [Caddy](https://caddyserver.com) and set up the following:
- A plaintext markdown site to demonstrate the process
- A URL shortener at https://g.o/
- A URL shortener at https://g.o/ (with DNS and TLS certificates too)
## HTTPS and Caddy
[Caddy](https://caddyserver.com) is a general-purpose HTTP server. One of its main features is automatic [Let's Encrypt](https://letsencrypt.org) support. We are using it here to serve HTTPS because it has a very, very simple configuration file format.
Caddy doesn't have a stable package in Ubuntu yet, but it is fairly simple to do it by hand.

### Installing Caddy
## Installing Caddy
One of the first things you should do when installing Caddy is picking the list of extra plugins you want in addition to the core ones. I generally suggest the following plugins:
- http.cors - [Cross-Origin Resource Sharing](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS), because we can't trust browsers
- http.git - it facilitates automatic deployment
- http.supervisor - run background processes
- tls.dns.yourprovider - enables Let's Encrypt via DNS (in my case tls.dns.cloudflare)
- [`http.cors`](https://caddyserver.com/docs/http.cors) - [Cross-Origin Resource Sharing](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS), because we can't trust browsers
- [`http.git`](https://caddyserver.com/docs/http.git) - it facilitates automatic deployment
- [`http.supervisor`](https://caddyserver.com/docs/http.supervisor) - run background processes
First we are going to need to download Caddy (please do this as root):
```console
curl https://getcaddy.com | bash -s personal http.cors,http.git,http.supervisor,tls.dns.cloudflare
curl https://getcaddy.com | bash -s personal http.cors,http.git,http.supervisor
chown root:root /usr/local/bin/caddy
chmod 755 /usr/local/bin/caddy
```

And open [https://g.o](https://g.o) on your iOS device:

margin-right: auto;

You can use the other [directives](https://caddyserver.com/docs) in the Caddy documentation to do more elaborate things. [When Then Zen](https://when-then-zen.christine.website) is hosted completely with [Caddy using the markdown directive](https://github.com/Xe/when-then-zen/blob/master/Caddyfile); but even this is ultimately a simple configuration.
