+
+### Registration
+
+The Equativ bidder adapter requires setup and approval from the Equativ service team. Please reach out to your account manager for more information to start using it.
+
+### Bid params
+
+{: .table .table-bordered .table-striped }
+| Name | Scope | Description | Example | Type |
+|------|-------|-------------|---------|------|
+| `networkId` | required | The network identifier you have been provided with. _See **Bid Parameter Usage** notes below for more information_. | `1234` | `integer` |
+| `siteId` | required | The placement site ID. _See **Bid Parameter Usage** notes below for more information_. |`1234` | `integer` |
+| `pageId` | required | The placement page ID. _See **Bid Parameter Usage** notes below for more information_. | `1234` | `integer` |
+| `formatId` | required | The placement format ID. _See **Bid Parameter Usage** notes below for more information_. | `1234` | `integer` |
+
+#### Bid Parameter Usage
+
+Different combinations of parameters are required depending upon which ones you choose to use.
+
+There are three options for passing bidder parameters:
+
+- **Option 1**. Specify `networkId` by itself (_without_ `siteId`, `pageId` and `formatId`), or
+- **Option 2**. Specify `siteId` _and_ `pageId` _and_ `formatId` (all together) _without_ `networkId`, or
+- **Option 3**. Specify _none_ of the above parameters, and instead use either `ortb2.site.publisher.id`, `ortb2.app.publisher.id` or `ortb2.dooh.publisher.id`
+
+See **Sample Banner Setup** for examples of these parameter options.
+
+### Supported Media Types
+
+{: .table .table-bordered .table-striped }
+| Type | Support |
+|---|---|
+| `banner` | Supported |
+| `video` | Not currently supported |
+| `native` | Not currently supported |
+
+### User Syncing
+
+To enable cookie syncing, make sure their configuration setup is properly invoked.
+
+This involves adding an entry for `setConfig()` that allows user syncing for iframes with `'equativ'` included as a bidder:
+
+```js
+pbjs.setConfig({
+  userSync: {
+    filterSettings: {
+      iframe: {
+        bidders: ['equativ'],
+      },
+    },
+  },
+});
+```
+
+And also making sure that storage is enabled for `equativ`:
+
+```js
+pbjs.bidderSettings = {
+  equativ: {
+    storageAllowed: true,
+  },
+};
+```
+
+### Configuration Example
+
+#### Sample Banner Setup
+
+As mentioned in the **Bid Parameter Usage** section, when including `'equativ'` as one of your available bidders your adunit setup, there are three general approaches to how you can specify parameters. Below are examples that illustrate them.
+
+#### Option 1 -- Using networkId as the only bid param
+
+```html
+<script>
+  var adUnits = [
+    {
+      code: 'div-123',
+      mediaTypes: {
+        banner: {
+          sizes: [
+            [600, 500],
+            [300, 600],
+          ],
+        },
+      },
+      bids: [
+        {
+          bidder: 'equativ',
+          // siteId, pageId and formatId are NOT
+          // required if networkId is provided instead
+          params: {
+            networkId: 42,
+          },
+        },
+      ],
+    },
+  ];
+
+  pbjs.que.push(function () {
+    pbjs.addAdUnits(adUnits);
+  });
+</script>
+```
+
+#### Option 2 - Using siteId, pageId and formatId as bid params
+
+```html
+<script>
+  var adUnits = [
+    {
+      code: 'div-123',
+      mediaTypes: {
+        banner: {
+          sizes: [
+            [600, 500],
+            [300, 600],
+          ],
+        },
+      },
+      bids: [
+        {
+          bidder: 'equativ',
+          // all 3 of the below params are required
+          // when used together in place of networkId
+          params: {
+            siteId: 1,
+            pageId: 2,
+            formatId: 3,
+          },
+        },
+      ],
+    },
+  ];
+
+  pbjs.que.push(function () {
+    pbjs.addAdUnits(adUnits);
+  });
+</script>
+```
+
+#### Option 3 - Using ortb2 for parameter info
+
+You can also, as an alternative to using bidder params, specify a value for `publisher.id` that may be nested under an `app`, `site` or `dooh` object. The Equativ adapter will, in turn, look for these property paths under the `ortb2` property of the request:
+
+- `ortb2.app.publisher.id`
+- `ortb2.site.publisher.id`
+- `ortb2.dooh.publisher.id`
+
