+
+Below are banner ad unit examples with required and optional parameters:
+
+```js
+    var adUnits = [
+            // Banner adUnit - required parameters
+            {
+                code: 'div-test-ad-1',
+                mediaTypes: {
+                    banner: {
+                        sizes: [[300, 250]]
+                    }

+                    }
+                }]
+            },
