+# Permutive RTD Provider
+{:.no_toc}
+

+
+## Overview
+This module reads cohorts from Permutive and attaches them as targeting keys to bid requests.
+
+## Usage
+Compile the Permutive RTD module into your Prebid build:
+```
+gulp build --modules=rtdModule,permutiveRtdProvider
+```
+
+> Note that the global RTD module, `rtdModule`, is a prerequisite of the Permutive RTD module.
+
+You then need to enable the Permutive RTD in your Prebid configuration, using the below format:
+
+```javascript
+pbjs.setConfig({
+ ...,
+ realTimeData: {
+ auctionDelay: 50, // optional auction delay
+ dataProviders: [{
+ name: 'permutive',
+ waitForIt: true, // should be true if there's an `auctionDelay`
+ params: {
+ acBidders: ['appnexus']
+ }
+ }]
+ },
+ ...
+})
+```
+
+## Supported Bidders
+The Permutive RTD module sets Audience Connector cohorts as bidder-specific `ortb2.user.data` first-party data, following the Prebid `ortb2` convention, for any bidder included in `acBidders`. The module also supports bidder-specific data locations per ad unit (custom parameters) for the below bidders:
+
+{: .table .table-bordered .table-striped }
+| Bidder | ID | Custom Cohorts | Audience Connector |
+| ----------- | ---------- | -------------------- | ------------------ |
+| Xandr | `appnexus` | Yes | Yes |
+| Magnite | `rubicon` | Yes | No |
+| Ozone | `ozone` | No | Yes |
+
+Key-values details for custom parameters:
+* **Custom Cohorts:** The module configuration will automatically reflect the SSP integrations (_Activations_) you have enabled in your Permutive dashboard. Any additional bidders you want to pass data to will need to be configured. Permutive cohorts will be sent in the permutive key-value.
+
+* **Audience Connector:** You'll need to define which bidders should receive Audience Connector cohorts. You need to include the `ID` of any bidder in the `acBidders` array. Audience Connector cohorts will be sent in the `p_standard` key-value.
+
+
