+# Experian Real-time Data Submodule
+
+## Overview
+
+    Module Name: Experian Rtd Provider
+    Module Type: Rtd Provider
+    Maintainer: team-ui@tapad.com
+
+## Description
+
+The Experian RTD module adds encrypted identifier envelope to the bidding object.
+
+## Usage
+
+### Build
+```
+gulp build --modules="rtdModule,experianRtdProvider,appnexusBidAdapter,..."
+```
+
+> Note that the global RTD module, `rtdModule`, is a prerequisite of the Experian RTD module.
+
+### Configuration
+
+Use `setConfig` to instruct Prebid.js to initialize the Experian RTD module, as specified below.
+
+This module is configured as part of the `realTimeData.dataProviders`
+
+```javascript
+pbjs.setConfig({
+  realTimeData: {
+    auctionDelay: 300,
+    dataProviders: [{
+      name: 'experian_rtid',
+      waitForIt: true,
+      params: {
+        accountId: 'ZylatYg',
+        bidders: ['sovrn', 'pubmatic'],
+        ids: { maid: ['424', '2982'], hem: 'my-hem' }
+      }
+    }]
+  }
+})
+```
