+### Banner
+
+#### `mediaTypes.banner` Parameters
+
+The StackAdapt bid adapter requires `sizes` to be defined in valid format. 
+See [mediaTypes.banner](https://docs.prebid.org/dev-docs/adunit-reference.html#adUnit.mediaTypes.banner) for defining mediaTypes parameters.
+
+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]]
+                    }
+                },
+                bids: [{
+                    bidder: 'stackadapt',
+                    params: {
+                        publisherId: '4cd53a92ra91',
+                    }
+                }]
+            },
+            // Banner adUnit - including optional parameters
+            {
+                code: 'div-test-ad-2',
+                mediaTypes: {
+                    banner: {
+                        sizes: [[300, 250]],
+                        pos: 1
+                    }
+                },
+                bids: [{
+                    bidder: 'stackadapt',
+                    params: {

+                            expdir: [1, 3]
+                        }
+                    }

+            }
+        ];
+```
+
+### Video
+
+#### `mediaTypes.video` Parameters
+
+The StackAdapt bid adapter requires `mimes`, `protocols`, `maxduration`, `api`, and `plcmt` to be defined in valid format.

+
+Below are video ad unit examples with required and optional parameters:
+
