+## GA4 Integration Example
+
+Since Universal Analytics has been sunset by Google, modern implementations can use GA4 event tracking.
+
+Example:
+
+```javascript
+window.adblockDetector.init({
+    found: function () {
+        if (typeof gtag === 'function') {
+            gtag('event', 'adblock_detected', {
+                adblock_status: 'detected'
+            });
+        }
+    },
+
+    notFound: function () {
+        if (typeof gtag === 'function') {
+            gtag('event', 'adblock_not_detected', {
+                adblock_status: 'not_detected'
+            });
+        }
+    }
+});
+```
+
+## Google Tag Manager (GTM)
+
+This library can also be integrated with Google Tag Manager using `dataLayer.push()` events.
