+## Video Support
+
+The MonetiseUp adapter supports Video ads via both direct VAST XML (`vastXml`) and VAST URLs (`vastUrl`).
+
+- **Instream**: Video ads support standard `instream` player contexts.
+- **Outstream**: For `outstream` context, a publisher-defined renderer (e.g. `renderer: { url, render }`) or `useCacheKey` must be supplied on the ad unit.
+
+## First Party Data (FPD)
+
+The adapter supports First Party Data (FPD) in multiple ways:
+
+- **Global FPD**: Automatically includes `pbjs.setConfig({ortb2: {...}})` site and user segment data.
+- **User IDs (EIDs)**: Automatically forwards external identifiers provided by Prebid User ID modules (`user.ext.eids`).
+- **Supply Chain**: Forwards `source.ext.schain` for transparent supply chain validation.
+- **Global Placement ID (GPID)**: Automatically extracts `ortb2Imp.ext.gpid` for ad server targeting.
+
+## User Sync
+
+The MonetiseUp adapter supports user synchronization to maximize bid yield:
+
+- **Client-Side**: Supports `iframe` and `image` syncs.
+- All privacy parameters (`gdpr`, `gdpr_consent`, `us_privacy`, `gpp`, `gpp_sid`) are automatically attached to sync requests.
+
+### Configuration Example
+
+```javascript
+pbjs.que.push(function() {
+  pbjs.addAdUnits(adUnits);
+
+  pbjs.setConfig({
+    debug: true,
+    userSync: {
+      filterSettings: {
+        iframe: {
+          bidders: ['mul'],
+          filter: 'include'
+        },
+        image: {
+          bidders: ['mul'],
+          filter: 'include'
+        }
+      }
+    }
+  });
+
+  pbjs.requestBids({
+    bidsBackHandler: function(bidResponses) {
+      console.log('Auction completed', bidResponses);
+    }
+  });
