+### Enabling subdomains
+
+You can enable support for subdomains with a simple nginx configuration:
+
+```nginx
+    # simple proxy from helia-sw-gateway.localhost to localhost:3000
+    server {
+        listen       80;
+
+        server_name ~^(?<subdomain>.+)\.ipfs\.helia-sw-gateway.localhost$ ~^(?<subdomain>.+)\.ipns\.helia-sw-gateway.localhost$ .helia-sw-gateway.localhost;
+
+        location / {
+            proxy_pass http://localhost:3000;
+            proxy_set_header Host $host;
+            proxy_set_header X-Forwarded-For $remote_addr;
+        }
+    }
+```
+
+You can then run `npm start` and your nginx server, and then visit `http://specs.ipfs.tech.ipns.helia-sw-gateway.localhost` in your browser to load the `specs.ipfs.tech` website via Helia, completely from the service worker.
