+## Required Caddyfile Changes
+
+### 1. Add a log block to your Caddyfile
+
+Add the logging configuration to a [snippet](https://caddyserver.com/docs/caddyfile/concepts#snippets) or to each individual site block:
+
+```caddyfile
+(hsts) {
+    log {
+        output file /var/log/caddy/access.log {
+            roll_size 100mb
+            roll_keep 10
+        }
+        format json
+    }
+    header {
+        Strict-Transport-Security "max-age=31536000; includeSubDomains; preload"
+        X-Content-Type-Options "nosniff"
+        Referrer-Policy "strict-origin-when-cross-origin"
+        Permissions-Policy "geolocation=(), microphone=(), camera=()"
+        -Server
+    }
+}
+
+some.dns.com {
+    import hsts
+    reverse_proxy 192.168.71.6:1378
+}
+```
+
+### 2. Create the log file with correct permissions (BEFORE reloading!)
+
+```bash
+mkdir -p /var/log/caddy
+touch /var/log/caddy/access.log
+chown caddy:caddy /var/log/caddy/access.log
+```
+
+### 3. Reload Caddy
+
+```bash
+systemctl reload caddy
+```
