 [GitHub Actions](https://help.github.com/en/articles/about-github-actions) provides the flexibility to build automated workflows for the software development lifecycle.
 
-GitHub Actions can be used to automate the workflow of creating a new revision of [Azure Container App](https://azure.microsoft.com/en-us/services/container-apps/).
-The aca-review-app runs the code contained in the GitHub pull request as an app in the Container App. The review app is then created as a new revision with a Weight of 0, each with a unique URL that can be shared. This is a great way to review and test code changes.
