Introduction

Working with different software (samples, compilers, demos) always requires an adequate environment.

Because i don’t want to pollute my normal environment (my running PC), i decided to use a virtual environment with Docker.

Luckily, VS Code supports this by using remote containers and working fully within these containers.
