 # Reverse Proxy
 
+## Caddy
+
+Caddy is a powerful and simple reverse proxy/webserver solution. Caddy will automatically manage HTTPS certs for any URL it is configured to serve.
+
+To set up Spacebar behind Caddy, simply add `reverse_proxy IP_TO_SPACEBAR_INSTANCE:3001` to your Caddyfile. **Remember to adjust your Spacebar configuration to use the external address on all public endpoints otherwise you will have CORS issues.**
+
+```
+spacebar.example.xyz {
+    reverse_proxy 10.0.0.99:3001
+}
+```
+
 ## NGINX
 
 Generally, our community sets up {{ project.name }} instances behind NGINX, a powerful reverse proxy.
