这是一本和计算机、项目建设、开放公共服务等相关的手册，由一些老师、同学以及朋友共同编写，也是我们对大学生涯的一个纪念。

这同时也是一份献给重医学弟学妹们的礼物。如果这本书能对你们的本科生涯有哪怕一丝一毫的帮助，都是对我们极大的鼓励和慰藉。

本书目前包括了以下部分(如果你有其他好的建议，或者想加入贡献者的行列，欢迎邮件 [PGuide Studio](mailto:losmosga@foxmail.com)

## 我也想写一些东西

项导文档欢迎各位加入建设，目前我们只是针对重医的同学们的情况编写了文档，涵盖的内容可能不齐全或存在可优化之处。欢迎各位有志之士加入建设。请参考[贡献指南](contribute.md)
或[电子邮件](mailto:losmosa@foxmail)

## 关于为什么自行开发与维护

项导文档之前在语雀也有存档，随着用户体量的增大，也暴露出一些问题：

1. 内容审核严格：语雀会对发布到互联网的团队文档进行严格审核，一旦检测到敏感词就会风控，极为不便；
2. 自定义程度低：不支持图标、markdown拓展等，组件库几乎等于没有；
3. 域名不可自定义：对SEO不友好，而且文档永久链接是Nano加密的字符组，不直观；
4. 需要注册和邀请：语雀需要每一位成员都进行注册和管理员审核协作，不方便；
5. 太过简单：对于markdown协作和前端开发未必是好事。

## 关于我们

项导文档，人人为我，我为人人。不必在意我们的名字，因为你就是下一个故事。
