+## How to run third party scripts off the main thread?
+
+To improve third-party scripts' loading time we may use the [Partytown](https://partytown.builder.io/) library.
+
+### What is [Partytown](https://partytown.builder.io/)? 
+
+Partytown is a lazy-loaded library to help relocate resource intensive scripts into a web worker, and off of the main thread. Its goal is to help speed up sites by dedicating the main thread to your code, and offloading third-party scripts to a web worker.
+
+Before running the GTM application outside of the main thread, it is necessary to install `vtex install vtex.partytown@0.x` in the environment where it is being developed or produced.
+Learn more at [VTEX Partytown](https://github.com/vtex-apps/partytown).
+
+⚠️ Partytown is a third-party beta solution, and some scripts may not run well with it. Double-check your site behavior before promoting it to master.
+
+### Enable secondary thread loading
+
+Once the partytown app is installed, simply navigate to `/admin/apps/vtex.google-tag-manager@version/setup/` and select `text/partytown`.
+
+![alt text](https://ibb.co/646qtpb)
+
+Now, google-tag-manager scripts are loaded outside the main thread, improving your site loading time.
 ## Restrictions
 
 In order to avoid performance problems and unforeseen behavior, our VTEX IO Google Tag Manager solution uses the native GTM **blacklist** feature. You can read more about this feature on the [Google Developer Guide](https://developers.google.com/tag-manager/web/restrict).
