+# Overview
+
+```
+Module Name: Mgid Bidder Adapter
+Module Type: Bidder Adapter
+Maintainer: [email protected]
+```
+
+# Description
+
+One of the easiest way to gain access to MGID demand sources  - MGID header bidding adapter.
+
+MGID header bidding adapter connects with MGID demand sources to fetch bids for display placements
+
+# Bid Parameters
+## Banner
+
+| Name | Scope | Type | Description | Example
+| ---- | ----- | ---- | ----------- | -------
+| `accountId` | required | String | The account ID from Mgid  | "123"
+| `placementId` | required | String | The placement ID from Mgid  | "123456"
+
+
+# Ad Unit and page Setup:
+
+```html
+ <!-- Prebid Config section -->
+ <script>
+     var PREBID_TIMEOUT = 2000;
+     var adUnits = [{
+         code: 'placement_div_id',
