+#### OpenRTB 2.5 supported parameters
+
+The adapter for Prebid.js supports the following options: `site.pagecat`, `site.content.cat` and `site.content.language`. You can set these parameters through the Prebid.js configuration setup functions: [pbjs.setConfig](https://docs.prebid.org/dev-docs/publisher-api-reference/setConfig.html) or [pbjs.setBidderConfig](https://docs.prebid.org/dev-docs/publisher-api-reference/setBidderConfig.html).
+An example of setting openrtb parameters for the entire prebid.js script.
+
+```javascript
+pbjs.setConfig({
+  ortb2: {
+    site: {
+      pagecat: ['IAB2-11', 'IAB2-12', 'IAB2-14'],
+      content: {
+        cat: ['IAB2-11', 'IAB2-12', 'IAB2-14'],
+        language: 'EN'
+      },
+    }
+  }
+});
+```
+
+An example of setting openrtb parameters only for the NextMillennium adapter.
+
+```javascript
+pbjs.setBidderConfig({
+  bidders: ['bidderB'],
+  config: {
+    ortb2: {
+      site: {
+        pagecat: ['IAB2-11', 'IAB2-12', 'IAB2-14'],
+        content: {
+          cat: ['IAB2-11', 'IAB2-12', 'IAB2-14'],
+          language: 'EN'
+        },
+      }
+    }
+  }
+});
