 'Features' are self-contained units of installation code and development container configuration. Features are designed
 to install atop a wide-range of base container images (**this repo focuses on `debian` based images**).

 ## Usage
 
-To reference a feature from this repository, add the desired features to a `devcontainer.json`. Each feature has a `README.md` that shows how to reference the feature and which options are available for that feature.
