+
+## User Sync
+Contxtful recommends enabling [User Syncing](https://docs.prebid.org/dev-docs/publisher-api-reference/setConfig.html#setConfig-Configure-User-Syncing) to optimize match rate and monetization.
+
+```javascript
+// Enable iframe usersync 
+pbjs.setConfig({
+  userSync: {
+    filterSettings: {
+      iframe: {
+        bidders: ['contxtful'],
+        filter: 'include'
+      }
+    }
+  }
+});
+
+// Allow local storage usage
+pbjs.bidderSettings = {
+  contxtful: {
+    storageAllowed: true
+  }
+}
+```
