qa's Issues

怎么提issue?

  • 首先希望大家,通过文字、图片和代码,正确的描述问题。

  • 提问前先翻一下列表里有没有相同的问题,
    注意closed的issue最好也翻一下,也可以在顶栏搜索This repository关键词。

  • 明确一下是哪方面的错误,issue的标题尽量简洁明确,要包括主要的关键字。

  • 尽量按格式写,用<!--扩起来的都可以删掉,preview中可以预览效果。
    ###开头表示的是这是三级标题,由于这是格式的一部分,尽量不要删掉。
    issue中使用的是Markdown语法格式的文档,可以看这篇文章学习语法,来达到更赏心悦目的排版。不会Markdown也无所谓,只要按照格式写即可。

系统环境和工具等的版本信息
每行开头用一个减号加空格,表示列表,例如:

显示为

  • windows 10
