+# Prebid Addressability Framework (OneKey)
+
+The PAF real-time data module in Prebid has been built so that publishers
+can quickly and easily setup the Prebid Addressability Framework and utilize OneKey.
+This module is used along with the pafRtdProvider to pass PAF data to your partners.
+Both modules are required. This module will pass paData to your partners
+while the pafRtdProvider will pass the transmission requests.
+
+Background information:
+- [prebid/addressability-framework](https://github.com/prebid/addressability-framework)
+- [prebid/paf-mvp-implementation](https://github.com/prebid/paf-mvp-implementation)
+
+## PAF Configuration
+
+The pafData module depends on paf-lib.js existing in the page.
+
+Compile the pafData module into your Prebid build.
+You will also want to add the pafRtdProvider module as well.
+
+`gulp build --modules=userId,pafIdSystem,rtdModule,pafRtdProvider,appnexusBidAdapter`
+
+There are no custom configuration parameters for PAF. The module
+will retrieve the PAF data from the page if available and pass the 
+information to bidders. Here is a configuration example:
+
+```javascript
+pbjs.setConfig({
+  userSync: {
+      userIds: [{
+          name: "pafData",
+          params: {}
+      }]
+    }],
+    auctionDelay: 50    // example auction delay, applies to all userId modules
+  }
+});
+```
+
+Bidders will receive the data in the following format:
+
+```json
+{
+    "identifiers": [{
+        "version": "0.1",
+        "type": "paf_browser_id",
+        "value": "da135b3a-7d04-44bf-a0af-c4709f10420b",
+        "source": {
+            "domain": "crto-poc-1.onekey.network",
+            "timestamp": 1648836556881,
+            "signature": "+NF27bBvPM54z103YPExXuS834+ggAQe6JV0jPeGo764vRYiiBl5OmEXlnB7UZgxNe3KBU7rN2jk0SkI4uL0bg=="
+        }
+    }],
+    "preferences": {
+        "version": "0.1",
+        "data": {
+            "use_browsing_for_personalization": true
+        },
+        "source": {
+            "domain": "cmp.pafdemopublisher.com",

+        }
+    }
+}
+```
+
+
+If the bidder elects to use pbjs.getUserIdsAsEids() then the format will be:
+
+```json
