If you've read through the entire "Getting Started" chapter, you have now created a complete Yii application. In the process, you have learned how to implement some commonly
displaying data in a paginated fashion. You have also learned how to use [Gii](https://github.com/yiisoft/yii2-gii/blob/master/docs/guide/README.md) to generate
code and want to understand the usage of a particular class, method, property. Usage of the class reference is best only after a contextual understanding of the entire framework.
Yii boasts a library of thousands of user-contributed extensions that can be easily plugged into your applications, thereby making your application development even faster and easier.
