+### Registration
+
+The Outbrain Adapter requires setup before beginning. Please contact us at prebid.org@outbrain.com.
+
+### Configuration
+
+#### Prebid.js
+
+The Outbrain adapter does not work without setting the correct bidder and usersync URLs.
+You will receive the URLs when contacting us.
+```
+pbjs.setConfig({
+    outbrain: {
+      bidderUrl: 'http://bidder-url.com',
+      usersyncUrl: 'http://usersync-url.com'
+    }
+});
+```
+
+#### Prebid server
+
+Similar to the Prebid.js configuration described above, our prebid server adapter requires you to configure the bidder and usersync URLs.
+You will receive the URLs when contacting us. 
+
+Please note that you need to replace the `<PREBID_SERVER_EXTERNAL_URL>` part with the actual external URL of the prebid server host.
