+### Configuration
+
+AJA recommends setting UserSync by iframe for monetization.
+
+For Prebid.js v1.15.0 and later:
+
+```javascript
+pbjs.setConfig({
+  userSync: {
+    filterSettings: {
+      iframe: {
+        bidders: '*',      // '*' represents all bidders
+        filter: 'include'
+      }
+    }
+  }
+});
+```
+
+For Prebid.js v1.14.0 and before:
+
+```javascript
+pbjs.setConfig({
+  userSync: {
+    iframeEnabled: true,
+    enabledBidders: ['aja']
+  }
+});
+```
