 This repository includes a [Dev Container config](./.devcontainer/devcontainer.json) (more about [Dev Containers](https://containers.dev/)) that declares all of the dependencies that you need to build and run the example. Dev Containers can be started locally with VSCode, but we recommend using GitHub's [Codespaces](https://github.com/features/codespaces) to quickly launch the Dev Container:
 
 1. Right-click to create a Codespace in a new tab or window:

     * *Important*: In order to view the example's front end, you must connect your local VSCode to the codespace: you cannot use VSCode in a browser window.
 2. Go to [https://github.com/codespaces](https://github.com/codespaces) and click the three dots next to the codespace you just created and then click `Open in Visual Studio Code`.
     * You can [set your default editor to VSCode for codespaces](https://docs.github.com/en/codespaces/customizing-your-codespace/setting-your-default-editor-for-github-codespaces) to avoid this step in the future. See [these instructions](https://docs.github.com/en/codespaces/developing-in-codespaces/opening-an-existing-codespace?tool=vscode) for more information.
