Any open-source project, especially a framework, requires great documentation and many have failed to achieve this. We feel that our documentation covers the API (Classes, Methods, etc) and we have a few guides but there can always be more. If you'd like to help us contribute then please write up anything you learn as a guide and submit it to us.
FuelPHP is a MVC (Model-View-Controller) framework that was designed from the ground up to have full support for HMVC as part of its architecture. But we didn't stop there, we also added ViewModels (also known as presentation models) into the mix which give you the option to add a powerful layer between the Controller and the View.
FuelPHP also supports a more router based approach where you might route directly to a closure which deals with the input uri, making the closure the controller and giving it control of further execution.
Whether you're an experienced PHP developer or a newcomer just getting started, there are many ways for you to participate in the Fuel project.
