 ## Deploy with GitHub Actions
 
+Deployment with GitHub Actions to live environments and Docker Hub is optional. Supply the following **GitHub Secrets** and **GitHUb Variables** if there is a need to deploy and push the client and server apps to live environments.
+
+> [!INFO]
+> Live server deployment to a new cloud hosting provider is currently under construction. Previous versions used to deploy it in a free-tier Heroku server.
