+code-server does not provide access to the official
+[Visual Studio Marketplace](https://marketplace.visualstudio.com/vscode). Instead,
+Coder has created a custom extension marketplace that we manage for open-source
+extensions. If you want to use an extension with code-server that we do not have
+in our marketplace please look for a release in the extension’s repository,
+contact us to see if we have one in the works or, if you build an extension
+locally from open source, you can copy it to the `extensions` folder. If you
+build one locally from open-source please contribute it to the project and let
+us know so we can give you props! If you have your own custom marketplace, it is
+possible to point code-server to it by setting the `SERVICE_URL` and `ITEM_URL`
