 == Description ==
 
-This plugin offloads JavaScript execution to a Web Worker, improving performance by freeing up the main thread.
+This plugin offloads JavaScript execution to a Web Worker, improving performance by freeing up the main thread. This should translate into improved [Interaction to Next Paint](https://web.dev/articles/inp) (INP) scores. _This functionality is considered experimental._
 
-In order to opt-in a script to be loaded in a worker, simply add `worker` script data to a registered script. For example,
+In order to opt in a script to be loaded in a worker, simply add `worker` script data to a registered script. For example,
 if you have a script registered with the handle of `foo`, opt-in to offload it to a web worker by doing:
 
 `
 wp_script_add_data( 'foo', 'worker', true );
 `
 
+Otherwise, the plugin currently ships with built-in integrations to offload Google Analytics to a web worker for the following plugins:
+
+* [Rank Math SEO](https://wordpress.org/plugins/seo-by-rank-math/)
+* [Site Kit by Google](https://wordpress.org/plugins/google-site-kit/)
+* [WooCommerce](https://wordpress.org/plugins/woocommerce/)
+
+Please monitor your analytics once activating to ensure all the expected events are being logged. At the same time, monitor your INP scores to check for improvement.

+This plugin relies on the [Partytown 🎉](https://partytown.builder.io/) library by Builder.io, released under the MIT license. This library is in beta and there are quite a few [open bugs](https://github.com/BuilderIO/partytown/issues?q=is%3Aopen+is%3Aissue+label%3Abug). The [Partytown configuration](https://partytown.builder.io/configuration) can be modified via the `wwo_configuration` filter. For example:
+
+`
+<?php
+add_filter( 'wwo_configuration', function ( $config ) {
+	$config['mainWindowAccessors'][] = 'wp'; // Make the wp global available in the worker (e.g. wp.i18n and wp.hooks).
