+
+## Overview
+
+The purpose of Reconciliation Real Time Data Provider is to allow publishers to collect supply chain structure information and vendor-specific impression IDs from ad creative suppliers. It reports the data to the Reconciliation Service, allowing publishers, advertisers and other supply chain participants to match and reconcile ad server, SSP, DSP and verification system log file records.
+Reconciliation SDK was created as part of TAG DLT initiative ([https://www.tagtoday.net/pressreleases/dlt_9_7_2020](https://www.tagtoday.net/pressreleases/dlt_9_7_2020)). 
+TAG recently led a twelve-month, cross-industry pilot in the UK that evaluated the feasibility and benefits of using Distributed Ledger Technology (DLT) to increase trust and transparency in digital advertising.

+
+Implementation works like this:
+
+1) Build the Reconciliation module into the Prebid.js package with:
+
+```
+gulp build --modules=reconciliationRtdProvider&...
+```
+
+2) Use `setConfig` to pass parameters to module 
+
+## Configuration
+
+This module is configured as part of the `realTimeData.dataProviders` object:
+
+```
+    pbjs.setConfig({
+        "realTimeData": {
+            dataProviders:[{          
+                name: "reconciliation",
+                params: {
+                    publisherMemberId: "test_prebid_publisher",
+                    allowAccess: true, //optional - false by default
+                }
+            }]
+        }
+    });
+```    
+

+| Name  |Type | Description   | Notes  |
+| :------------ | :------------ | :------------ |:------------ |
+| name  | String | Real time data module name | Always 'reconciliation' | 
+| params  | Object   | |   |
+| params.publisherMemberId  |String   |Unique Publisher ID|   |
+| params.allowAccess  |Boolean   |Share AdUnit IDs with advertiser Reconciliation Tags| Optional. Default to `false`|
+
+
+
+## Output
+
+For each ad slot, the module returns custom targeting values used to match impressions (publisher-adserver-advertiser).
+The module also tracks AdUnit initialization and impressions ('impression' message is sent by the Reconciliation Tag in ad markup).
+
+Custom targetings example:
+```
+{
+  "slotA":{
+      "RSDK_AUID": "/slotA-Unit",
+      "RSDK_ADID": "b5bbc103-00e9-499d-9637-bdba05b65427"
+  },
+  "slotB":{
+      "RSDK_AUID": "/slotB-Unit",
+      "RSDK_ADID": "325da95e-e37d-45fa-a46f-8ff91168b121"
+  }
+}
+```
