This document discusses how Symfony was created to help build robust web applications for enterprise use. It provides an overview of Symfony's goals like speeding up development and replacing repetitive code. The document also presents an example project structure using technologies like Nginx, PHP-FPM, MySQL, and orchestration tools. It describes the development workflow including local builds, continuous integration with tools like Jenkins, and deployment with Capifony.
