能不能（有没有）一套方便学习的文档？

像material-ui这样的，基本一边查文档就可以上手开发了。或者像阿里巴巴的antd-ui那样的也可以。
https://material.angular.io/

感觉你们的文档不是很友好。

Start by reviewing the existing uni-app documentation and the referenced material.angular.io example. Define a beginner-friendly documentation structure and compare its coverage and usability with the examples named in the issue; done means the requested learning path is clearly documented and easy to follow.
