We are developing Dolphin to be as easy to use as possible. It has a collection of tools in the admin panel which are useful and uncomplicated to manage, customize and modify Dolphin. We have Trac pages with useful tutorials, and our forum is full of useful information and advice.
Professional developers do modifications and offer them on the Unity market, so if you need an additional module, you can order it and install. All the packages offered on Unity have installation instructions and product owners can be contacted on Unity directly for support inquiries.
