 Since Positron is built on [Code OSS](https://github.com/microsoft/vscode), you can use VS Code extensions in Positron. Your extensions installed for Positron are _separate_ from the extensions you have installed for VS Code, and they won't interfere with each other. Positron bundles several extensions, including those for Quarto, Jupyter notebooks, and Pyright. To see bundled extensions, search for `@builtin` under the Extensions tab. To further filter the list, you can add a search term, such as `@builtin Positron`

 ### Installing extensions
 
-Positron has an Extensions view, just like VS Code. The primary difference is that when you browse extensions in Positron, the extensions don't come from VS Code's Marketplace. Instead, they come from a third-party marketplace, [OpenVSX](https://open-vsx.org/). This is necessary for licensing reasons; Microsoft doesn't permit access to the Marketplace from non-official clients.

This is necessary for licensing reasons; Microsoft does not permit access to the Marketplace from non-official clients. 
 
 OpenVSX includes most popular VS Code extensions, but not all; some authors don't bother to publish their extensions to OpenVSX (it's an extra step) and others don't keep the OpenVSX version of the extension up to date. Open VSX has a suggested [template](https://github.com/open-vsx/publish-extensions/blob/master/docs/external_contribution_request.md) to request that the authors of an extension cross-publish their extension on the Open VSX Registry.

-* Our aspirations for Positron go far beyond what is possible via only extensions. Ultimately, VS Code's Extension API doesn't provide enough leverage to modify the main "workbench" surface.
+* Our aspirations for Positron go far beyond what is possible via only extensions. Ultimately, VS Code's Extension API does not provide enough leverage to modify the main "workbench" surface.
 * To deliver a truly excellent data science experience, we need to change and augment core components and UI elements that are outside the scope of VS Code's extension API.
 * We have developed some components as extensions for use in both Positron and VS Code, such as Quarto and Shiny for R/Python. However, given the additional API surface in Positron, we plan to progressively enhance these and future extensions when installed in Positron.
