 ### Build & Test
 
-The containers can be built and tested locally by importing this repository in VS Code with the [Remote Containers](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers) plug-in installed. As a prerequisite an OCI compatible container engine needs to be installed on the host system. Alternatively a GitHub Codespace can be started.

+If you already have VS Code and a OCI compatible container engine 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/philips-software/amp-devcontainer)
