+| Name | Scope | Description | Example | Type |
+|---------------|----------|--------------------|------------------------------|----------|
+| `account` | required | Adhese account name | `'demo'` | `string` |
+| `location` | required | Adhese location name | `'_adhese_prebid_demo_'` | `string` |
+| `format` | required | Adhese format name | `'leaderboard'` | `string` |
+| `data` | optional | Custom target data | `{ 'ci': [9000, 9050] }` | `object` |
+
+### Configuration
+
+Adhese supports 'iframe' UserSync configuration only. 
+
+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: ['adhese']
+ }});
+```
+
+Note: Combine the above the configuration with any other UserSync configuration. Multiple setConfig() calls overwrite each other and only last call for a given attribute will take effect.
