+## GitHub Copilot Models
+
+If you have access to **GitHub Copilot in Visual Studio Code**, 
+GenAIScript will be able to leverage those [language models](https://code.visualstudio.com/api/extension-guides/language-model) as well.
+
+This mode is useful to run your scripts without having a separate LLM provider or local LLMs. However, those models are  not available from the command line
+and have additional limitations and rate limiting defined by the GitHub Copilot platform.
+
+There is no configuration needed as long as you have GitHub Copilot installed and configured in Visual Studio Code.
+
+<Steps>
+
+<ol>
+
+<li>run your script</li>
+<li> 
+select the **Visual Studio Code Language Chat Models** option when configuring the model
+</li>
+<li>
+select the best chat model that matches the one you have in your script
+</li>
+
+</ol>
+
+</Steps>
+
+The mapping of GenAIScript model names to Visual Studio Models is stored in the settings.

 ## Local Models
 
 There are many projects that allow you to run models locally on your machine,
