-Until something more open comes around, we use the Microsoft Marketplace/Extensions in the `product.json` file. Those links are licensed under MIT as per [the comments on this issue.](https://github.com/Microsoft/vscode/issues/31168#issuecomment-317319063)
+The `product.json` file is set up to use [open-vsx.org](https://open-vsx.org/) as extension gallery, which has an [adapter](https://github.com/eclipse/openvsx/wiki/Using-Open-VSX-in-VS-Code) to the Marketplace API used by VS Code. Since that is a rather new project, you will likely miss some extensions you know from the VS Code Marketplace. You have the following options to obtain such missing extensions:
+
+ * Ask the extension maintainers to publish to [open-vsx.org](https://open-vsx.org/) in addition to the VS Code Marketplace. The publishing process is documented in the [Open VSX Wiki](https://github.com/eclipse/openvsx/wiki/Publishing-Extensions).
+ * Create a pull request to [this repository](https://github.com/open-vsx/publish-extensions) to have the [@open-vsx](https://github.com/open-vsx) service account publish the extensions for you.
+ * Download and [install the vsix files](https://code.visualstudio.com/docs/editor/extension-gallery#_install-from-a-vsix).
+ * Modify the `extensionsGallery` section of the `product.json` file in your VSCodium installation to use the VS Code Marketplace as shown below. However, note that [it is not clear whether this is legal](https://github.com/microsoft/vscode/issues/31168).

 For more information on getting all the telemetry disabled and tips for migrating from Visual Studio Code to VSCodium, have a look at this [Docs](https://github.com/VSCodium/vscodium/blob/master/DOCS.md) page.
 
-### Extension Licensing
+### Extensions and the Marketplace
+According to the VS Code Marketplace [Terms of Use](https://aka.ms/vsmarketplace-ToU), _you may only install and use Marketplace Offerings with Visual Studio Products and Services._ For this reason, VSCodium uses [open-vsx.org](https://open-vsx.org/), an open source registry for VS Code extensions. See the [Extensions + Marketplace](https://github.com/VSCodium/vscodium/blob/master/DOCS.md#extensions-marketplace) section on the Docs page for more details.
+
 Please note that some Visual Studio Code extensions have licenses that restrict their use to the official Visual Studio Code builds and therefore do not work with VSCodium. See [this note](https://github.com/VSCodium/vscodium/blob/master/DOCS.md#proprietary-debugging-tools) on the Docs page for what's been found so far and possible workarounds.
