 3. Define your ad units in the `adUnit` object. This includes the details about the ad slots such as the media types, ad size, and ad code. For more information about this object, see Prebid's [Ad Unit Reference](https://docs.prebid.org/dev-docs/adunit-reference.html) documentation.
 4. Enable user syncing by adding the following code in the [pbjs.setConfig()](https://docs.prebid.org/dev-docs/publisher-api-reference/setConfig.html) function. Index strongly recommends enabling user syncing through iFrames, though we do also support image-based syncing. This functionality improves DSP user match rates and increases the Index bid rate and bid price. Make  sure to call `pbjs.setConfig()` only once. This configuration is optional in Prebid, but required by Index.  <br />

 **Example:** 
 ```javascript
-pbjs.setConfig({
-    userSync: {
-        iframeEnabled: true,
-        filterSettings: {
-            iframe: {

 5. (Optional) Set up First Party Data (FPD) using the Index bidder-specific FPD (preferred method) setting or the Prebid FPD module. For more information, see the [Set up First Party Data (FPD)](#set-up-first-party-data-fpd) section below.
 6. (Optional) If you want to monetize instream video, you need to enable a cache endpoint in the [pbjs.setConfig()](https://docs.prebid.org/dev-docs/publisher-api-reference/setConfig.html) function as follows: <br />
 ```javascript
-pbjs.setConfig({
-    cache: {
-        url: 'https://prebid.adnxs.com/pbc/v1/cache'
