 ### Before You Begin
 
-The Panxo adapter requires the Panxo Signal script to be installed on your page before Prebid.js loads. Please register at [app.panxo.ai](https://app.panxo.ai) to obtain your property key and Signal script endpoint.
+The Panxo adapter requires the [Panxo RTD Module](/dev-docs/modules/panxoRtdProvider.html) to be included in your Prebid.js build. The RTD module detects AI-referred traffic and enriches bid requests with classification signals that the adapter needs to participate in the auction.
 
-**Important**: Without the Signal script setting the `panxo_uid` in localStorage, the adapter will not participate in the auction.
+Please register at [app.panxo.com](https://app.panxo.com) to obtain your `siteId` (for the RTD module) and `propertyKey` (for the bid adapter).
+
+**Important**: Without the Panxo RTD module configured, the adapter will not participate in the auction.
