+## Description
+
+Analytics Adapter for IM-DMP.
+
+Please visit [intimatemerger.com/im-uid](https://intimatemerger.com/r/im-uid) and request your Customer ID to get started.
+
+If you are an existing publisher and you already use [IM-UID](/dev-docs/modules/userid-submodules/imuid.html), you can use the same Customer ID for this analytics adapter.
+
+By enabling this adapter, you agree to Intimate Merger's privacy policy at <https://corp.intimatemerger.com/privacypolicy/>.
+
+## Configuration
+
+To enable the IM Analytics adapter, configure it in your Prebid.js setup. Use `imAnalytics` as the provider and provide the appropriate `options`.
+
+### Analytics Options
+
+{: .table .table-bordered .table-striped }
+| Parameter | Scope | Type | Example | Description |
+| --- | --- | --- | --- | --- |
+| `cid` | optional | number | 5126 | The Customer ID provided by Intimate Merger. |
+| `waitTimeout` | optional | number | 1500 | Wait time in milliseconds before sending batched requests. (Default: 1500) |
+
