+### Pin a specific VS Code Web version

+By default, this module installs the latest. To pin a specific version, retrieve the commit ID from the [VS Code Update API](https://update.code.visualstudio.com/api/commits/stable/server-linux-x64-web) and verify its corresponding release on the [VS Code GitHub Releases](https://github.com/microsoft/vscode/releases).
