+## Serving Reports with Nginx
+
+To expose the generated HTML dashboards and JSON files over HTTP you can use a
+simple Nginx server block. Point the `root` directive to the repository's
+`output/` directory and optionally restrict access to your local network.
+
+```nginx
+server {
+    listen 80;
+    server_name example.com;
+
+    # Path to the generated reports
+    root /path/to/ngxstat/output;
+
+    location / {
+        try_files $uri $uri/ =404;
+    }
+
+    # Allow access only from private networks
+    allow 192.0.0.0/8;
+    allow 10.0.0.0/8;
+    deny  all;
+}
+```
+
+With this configuration the generated static files are served directly by
+Nginx while connections outside of `192.*` and `10.*` are denied.
