 ## Description
 
+### Image variants
+
+Two devcontainers are published towards the [GitHub Container Registry](https://ghcr.io/):
+
+- [amp-devcontainer](https://github.com/orgs/philips-software/packages/container/package/amp-devcontainer); the base container including all tools mentioned below
+- [amp-devcontainer-vscode](https://github.com/orgs/philips-software/packages/container/package/amp-devcontainer-vscode); as above, but including a full [Visual Studio Code](https://code.visualstudio.com/) configuration that is compatible with [GitHub Codespaces](https://github.com/features/codespaces)
+
+### amp-devcontainer
+
 The amp-devcontainer built from this repository contains compilers and tools to facilitate modern (embedded) C++ development.
 The amp-devcontainer includes support for host- and cross-compilation using gcc, arm-gcc and clang compilers.
 Next to the compilers there is support for code-coverage measurement, mutation testing (using [mull](https://github.com/mull-project/mull)), fuzzing (using [libfuzzer](https://www.llvm.org/docs/LibFuzzer.html)) and static analysis (clang-format, clang-tidy, clangd, include-what-you-use).
 The default build system is set up to use CMake, Ninja and CCache.
 
 For the full list of all included tools and tool versions see the [Dependency Graph](https://github.com/philips-software/amp-devcontainer/network/dependencies), the SBOM published with a [release](https://github.com/philips-software/amp-devcontainer/releases), or the SBOM attached to the image.
 
-## Build & Test
+### amp-devcontainer-vscode
 
-The container can be built and tested locally by importing this repository in VS Code with the `Dev Containers` (ms-vscode-remote.remote-containers) plug-in installed. As a prerequisite Docker needs to be installed on the host system. As an alternative a GitHub Codespace can be started.
+The amp-devcontainer-vscode is a, slightly more, opinionated variant that can be used in Visual Studio Code or GitHub Codespaces without any additional configuration. All included tools are set-up and necessary plug-ins will be installed at container start. This behavior is implemented by appending devcontainer metadata to an image label according to the [specifications](https://containers.dev/implementors/reference/#labels). It is possible to override, amend or change the options following this [merge logic](https://containers.dev/implementors/spec/#merge-logic).
 
-A test task is available to run the included `bats` tests. Choose `Tasks: Run Test Task` from the command pallette.
+## Usage
 
-## Verify image signature
+### Verify image signature
 
-The container image is signed with [SigStore](https://www.sigstore.dev/) [Cosign](https://docs.sigstore.dev/signing/quickstart/) using a keyless signing method.
+The container images are signed with [SigStore](https://www.sigstore.dev/) [Cosign](https://docs.sigstore.dev/signing/quickstart/) using a keyless signing method.
 
 The signature can be verified with the following command (using Docker), verifying that the image is actually signed by the GitHub CI system:
 
+> amp-devcontainer
+
 ```sh
 docker run --rm gcr.io/projectsigstore/cosign verify ghcr.io/philips-software/amp-devcontainer --certificate-oidc-issuer https://token.actions.githubusercontent.com --certificate-identity-regexp https://github.com/philips-software/amp-devcontainer
 ```
 
-## Usage
+> amp-devcontainer-vscode
+
+```sh
+docker run --rm gcr.io/projectsigstore/cosign verify ghcr.io/philips-software/amp-devcontainer-vscode --certificate-oidc-issuer https://token.actions.githubusercontent.com --certificate-identity-regexp https://github.com/philips-software/amp-devcontainer
+```
+
+The resulting containers can be used in a `.devcontainer.json` file or in a `.devcontainer` folder.
 
-The resulting container can be used in a `.devcontainer` folder. While the example uses the `latest` tag, it is recommended to pin to a specific version. Or better yet, a specific SHA.
