# What do I do with the Trustmary Tag?

**Trustmary Tag is a code snippet found in the [Settings](https://app.trustmary.com/settings/developer) of your account, and in the settings of your popup widgets.

This script is responsible for loading all the correct things into your Trustmary widgets. Each Trustmary account has their own unique code. In most cases, you won't have to make yourself acquainted with this script, as it's automatically loaded with our Review Widget script (the shorter one found in widget settings).

In some rare cases, though, you'll need to grab the tag and install it to your site's head element. The most common case for this is when a platform or CMS doesn't support our other method of embedding. Installing the tag to the head element, and separately installing a “div” version of the widget code solves 99% of the embedding issues.

See our [React & headless site](https://help.trustmary.com/en/article/how-to-add-reviews-to-a-react-site-s0gmng/) installation instructions for how to do this. **
