 Additionally, you can install the package with npm. This is mostly useful for when you're integrating ArcAds into a single page application or a JavaScript heavy project. Most implementations should just include the script in the page header.

-You can enable Prebid.js on the wrapper by adding a `prebid` object to the wrapper initialization and setting `enabled: true`. You can also optionally pass it a `timeout` value which corresponds in milliseconds how long Prebid.js will wait until it closes out the bidding for the advertisements on the page. By default, the timeout will be set to `700`.
+You can enable Prebid.js on the wrapper by adding a `prebid` object to the wrapper initialization and setting `enabled: true`. If `enabled` is `undefined`, `prebid` can still be used by providing a valid `bids` object. You can also optionally pass it a `timeout` value which corresponds in milliseconds how long Prebid.js will wait until it closes out the bidding for the advertisements on the page. By default, the timeout will be set to `700`.
