How to Use Caddy

1. Make a Caddyfile

The Caddyfile is a text file that configures Caddy. It's designed to be easy to type and hard to get wrong.

The first line of the Caddyfile is always the address(es) of the site to serve.

You can define as many sites as you want; Caddy supports virtual hosting and lots of other features!

2. Run Caddy

All you have to do is run caddy and voilà! Caddy automatically loads your Caddyfile if it's in the same folder. For production sites, HTTPS is on by default!

3. Open your Browser

Type your site's address to see it in action. Live sites are redirected to HTTPS for you.

Caddy is great for building sites at home or work, and for serving sites in production. Try it out!
