The Next-Gen User Interface kit is a plugin for Unity 3D. It has the great advantage of being easy to use, very powerful, and optimized compared to Unity's built-in GUI system called UnityGUI.

Using this plugin, you can create main menus and in-game user interfaces. It also comes with useful generic methods and an event system that can come in handy.

In this first chapter, we'll import the plugin in a new project and create our first UI. After displaying texts and sprites, we'll take a look under the hood to understand NGUI's global structure and review its important parameters.
