+## Bid Params
+
+{: .table .table-bordered .table-striped }
+| Name          | Scope    | Description                | Example                                   | Type      |
+|---------------|----------|----------------------------|--------------------------------------     |-----------|
+| `tagId`       | required*| Media Tradecraft tag ID    | `"testnexx"`                              | `string`  |
+| `placement`   | required*| Media Tradecraft placement | `"test.com_header_ad"`                    | `string`  |
+
+*You *must* only include one ID field - either `tagId` or `placement`, not both. If you have questions on which parameter to use, please reach out to your Account Manager.
+The `tagId` and `placement` are **mutually exclusive** but at least one is required. If you pass both, `tagId` takes precedence.
+
+## Bidder Config
+
+You can allow writing in localStorage `pbjs.bidderSettings` for the bidder `mtc`
+
+{% include dev-docs/storageAllowed.md %}
+
+```javascript
+pbjs.bidderSettings = {
+    mtc: {
+        storageAllowed : true
+    }
+}
+```
+
+## First Party Data
+
+Publishers should use the `ortb2` method of setting [First Party Data](https://docs.prebid.org/features/firstPartyData.html).
+
