-Embed the GitBook Docs Assistant in your product or website.
+Embed your GitBook docs in your product or website.
+
+The Docs Embed can contain two tabs:
+- **Assistant**: The [GitBook Assistant](https://gitbook.com/docs/publishing-documentation/gitbook-ai-assistant) - an AI-powered chat interface to help users find answers
+- **Docs**: A browser for navigating your documentation site
+
+The embed is set up automatically based on your site's configuration. You can optionally customize and override the configuration with custom actions, tools, suggested questions, [Authenticated Access](https://gitbook.com/docs/publishing-documentation/authenticated-access), and more. See the [Configuration](#configuration) section for all available options.
 
 # Usage

+## As a standalone script from your docs site
 
-All GitBook docs site includes a script to easily embed the docs assistant as a widget on your website.
+All GitBook docs sites include a script to easily add the Docs Embed as a widget on your website.
 
 The script is served at `https://docs.company.com/~gitbook/embed/script.js`.
 
-You can find the embed script from your docs site settings, or you can copy the following and replace the `docs.company.com` by your docs site hostname.
+You can find the embed script from your docs site settings, or you can copy the following and replace `docs.company.com` with your docs site hostname.
