-Caching is done using the [actions/cache](https://github.com/actions/cache/tree/v4) (lookup only) and [docker/build-push-action](https://github.com/docker/build-push-action) actions. Users have to explicitly provide the cache key for the first step. For example, if you are dealing with an R package, you can cache the dependencies by passing the key `${{ hashFiles('DESCRIPTION') }}` to the `first-step-cache-key` input. That way, the first step will only be executed if the dependencies change.
