Up(sun) and running with Symfony Demo

The guide provides a comprehensive walkthrough on hosting and configuring a Symfony Demo project on the Upsun platform, highlighting its simplicity and efficiency. It begins by explaining how to create a new Symfony Demo application using specific commands and the --upsun option to auto-configure the project for Platform as a Service (PaaS). This setup generates a YAML configuration file in a designated folder to manage application behavior during deployment. The guide then details the process of creating an Upsun project via the Symfony CLI, linking local source code to the new project, and deploying it using a series of straightforward commands. This approach aims to streamline the deployment process for users focusing on enhancing user experiences rather than managing Symfony infrastructure, with additional tips provided for further development and configuration. The guide concludes by mentioning upcoming resources and tutorials related to Symfony and Upsun.
