+#### First Party Data
+
+In release 1.6.4 and later, publishers should use the `ortb2` method of setting [First Party Data](https://docs.prebid.org/features/firstPartyData.html). The following fields are supported:
+
+* ortb2.site.content.data[]
+
+If `ad-generation.jp` is specified for ortb2.site.content.data[].name and `546` is specified for ortb2.site.content.data[].ext.segtax,
+`ortb2.site.content.data[].segment[].name` and `ortb2.site.content.data[].segment[].value` can be any string value.
+
+Example first party data that's available to all bidders and all adunits:
+
+```javascript
+pbjs.setConfig({
+    ortb2: {
+        site: {
+            content: {
+                data: [{
+                    name: "ad-generation.jp",
+                    ext: {
+                        segtax: 546
+                    },
+                    segment: [
+                        { name: "news_category", value: "Sports_Sumo" },// name and value must be string types
+                        { name: "local_gourmet", value: "sushi" },
+                        { name: "location", value: "tokyo" }
+                    ]
+                }]
+            }
+        },
+    }
+});
+```
