Think of Neos as an open source Content Application Platform based on its own PHP framework Flow. The content management features are resting within a larger context that allows you to build a perfectly customized experience.
Requirements will change during the lifecycle of your project. This is why we put a lot of effort into making Neos as flexible as possible, while presenting a purpose-built, clean interface.
The most basic way of editing content in Neos is available by just clicking what you want to change, working out the changes and pressing the publish button. It's that simple.
