You have nothing to do to host your application on Scalingo, we'll detect the Lumen Framework and setup the configuration for it. Just push your code.
Laravel Lumen is a stunningly fast PHP micro-framework for building web applications with expressive, elegant syntax. We believe development must be an enjoyable, creative experience to be truly fulfilling. Lumen attempts to take the pain out of development by easing common tasks used in the majority of web projects, such as routing, database abstraction, queuing, and caching.
Documentation for the framework can be found on the Lumen website.
The Lumen framework is open-sourced software licensed under the MIT license
