+Pangle server-side Prebid Server adapter supports `banner`, `video`, `native` media types. But Pangle client-side Prebid.js adapter supports only `banner` media types, doesn't support `video` and `native`.
+
+### Test Parameters
+
+```javascript
+var adUnits = [
+    {
+        code: 'test-div',
+        mediaTypes: {
+            banner: {
+                sizes: [[300, 250]],  // a display size
+            }
+        },
+        bids: [
+           {
+               bidder: "pangle",
+               params: {
+                    token: "aaaaa",
+                    placementid: '1234', // string 
+                    appid: '1234' // string 
+                }
+           }
+       ]
+    }
+];
+```
+
+### User Sync
+
+Add the following code to enable user sync. Pangle strongly recommends enabling user syncing through iFrames. This functionality improves partners' user match rates and increases the Pangle bid rate and bid price. Be sure to call `pbjs.setConfig()` only once.
+
+```javascript
+pbjs.setConfig({
+    userSync: {
+        iframeEnabled: true,
+        userIds: [
+          {
+            name: 'sharedId',
+            storage: {
+              name: 'sharedId', // name of the 1st party cookie
+              type: 'cookie',
+              expires: 365,
+            },
+          },
+        ],
+    }
+});
+```
