+### Adtelligent
+
+The [Adtelligent](https://adtelligent.com) ID system is a unique per-session user identifier for providing high quality DMP data for advertisers
+
+Add it to your Prebid.js package with:
+
+{: .alert.alert-info :}
+gulp build --modules=userId,adtelligentIdSystem
+
+#### Adtelligent Configuration
+
+adtelligentIdSystem adapter doesn't require any configuration or storage params. The adapter performs asynchronously and to achieve better performance it is recommended to set the `storage` object `refreshInSeconds` to a short period, such as ten minutes. At the end of the set storage refresh the adapter will refresh its configuration.
+
+#### Adtelligent Example
+ 
+{% highlight javascript %}
+ pbjs.setConfig({
+     userSync: {
+         userIds: [{
+             name: 'adtelligent'
+         }]
+     }
+ });
+{% endhighlight %}
+
+Example with a short storage for ~10 minutes and refresh in 5 minutes: 
+
+{% highlight javascript %}
+    pbjs.setConfig({
+        userSync: {
+            userIds: [{
+                name: 'adtelligent',
+                storage: {
+                    type: "html5",
+                    name: "adt_id",
+                    expires:0.003,
+                    refreshInSeconds: 60 * 5
