+## Caddy Integration ##
+
+[Caddy](https://caddyserver.com/docs/errors) supports custom error-pages using `errors` directive. 
+
+File: Caddyfile
+
+Example - assumes HttpErrorPages are located into `/var/www/error`.
+
+```Caddyfile
+www.yoursite.com {
+    
+    // Other configurations
+
+    errors {
+        404 /var/www/error/HTTP404.html
+    }
+
+    // Other configurations
