I was looking for a way to show how our libraries like Adrenaline, Pathfinder and Disco work in a "real world" application. I came up with the idea to build just another simple flat-file CMS. AddItEasy might be the first flat-file CMS based on a PSR-7 implementation which adds a nice touch: We can easily create a static file export from the content. That means that you do not need to upload addItEasy to your server, you can simply export the files and e.g. let GitHub host the static HTML pages.
