 - `.github/workflows/vib-build.yml`: This file contains the GitHub Actions workflow to check for updates to the base image and build the Vib image on push and pull requests.
   - It uses the [`vib-gh-action`](https://github.com/Vanilla-OS/vib-gh-action) to build the recipe and upload it as an artifact. The generated artifact is then built using Docker's actions and pushed to GHCR (**Note**: The image with the respective branch tags is published to GHCR only on push actions to the branches in your repository or on tags and not on pull requests).
   - The action runs automatically on a schedule checking updates to the base image using [Differ](https://github.com/Vanilla-OS/Differ).
+- `.github/workflows/release.yml`: This file contains the GitHub Actions workflow to automatically create a GitHub release when a tag is created and it uploads the generated Containerfile to the release for future reference.
 - `.github/dependabot.yml`: This file contains the configuration for GitHub's Dependabot to check for updates to the GitHub actions used in the workflow files monthly and when it finds a new version it creates a PR in your repository.
 - `includes.container`: The files included in this directory are added by default to your image to the specified location (**Note**: It also contains ABRoot's configuration file).
 - `modules`: This directory contains the modules that are used to customize the image. You can add your modules to this directory.
