 # Code - OSS Development Container
 
+[![Open in Remote - Containers](https://img.shields.io/static/v1?label=Remote%20-%20Containers&message=Open&color=blue&logo=visualstudiocode)](https://vscode.dev/redirect?url=vscode://ms-vscode-remote.remote-containers/cloneInVolume?url=https://github.com/microsoft/vscode)
+
 This repository includes configuration for a development container for working with Code - OSS in a local container or using [GitHub Codespaces](https://github.com/features/codespaces).
 
 > **Tip:** The default VNC password is `vscode`. The VNC server runs on port `5901` and a web client is available on port `6080`.
 
 ## Quick start - local
 
+If you already have VS Code and Docker installed, you can click the badge above or [here](https://vscode.dev/redirect?url=vscode://ms-vscode-remote.remote-containers/cloneInVolume?url=https://github.com/microsoft/vscode) to get started. Clicking these links will cause VS Code to automatically install the Remote - Containers extension if needed, clone the source code into a container volume, and spin up a dev container for use.
+
 1. Install Docker Desktop or Docker for Linux on your local machine. (See [docs](https://aka.ms/vscode-remote/containers/getting-started) for additional details.)
 
 2. **Important**: Docker needs at least **4 Cores and 8 GB of RAM** to run a full build. If you are on macOS, or are using the old Hyper-V engine for Windows, update these values for Docker Desktop by right-clicking on the Docker status bar item and going to **Preferences/Settings > Resources > Advanced**.
