+### User ID Support
+
+SmartyTech adapter supports all Prebid.js User ID modules. User IDs are automatically included in bid requests when available.
+
+### Privacy and Consent Support
+
+The SmartyTech adapter supports the following privacy frameworks:
+
+- **GDPR (TCF EU)**: Full support for GDPR consent strings
+- **CCPA/USP**: Support for California Consumer Privacy Act and US Privacy
+- **GPP**: Support for Global Privacy Platform
+- **COPPA**: Support for Children's Online Privacy Protection Act
+
+### Additional Configuration
+
+It is possible to configure requests to be split into chunks so as to have fewer bid requests in a single http request (default value is 10).
+
+```javascript
+pbjs.setBidderConfig({
+    config: {              
+        smartytech: {
+            chunkSize: 5   // makes 1 http request per 5 ad units configured
+        }
+    }
+});
+```
