好吧，刚才我看到下面有这样一段：
（真的很想吐槽：哪里方便了？还没到这里就已经结束了，我谢谢您嘞~） 话虽如此，此 PR 我认为还是有必要的，只是内容可以更精简一些，直接提示读者即可。 |

我看了下，确实这个语言教程前面的 即时计算被直接依赖的值、文件求值、以及后面对词法、句法、语法的详细说明，对单纯的「Nix 语言入门」而言都显得不是很有必要，有点分散了注意力，你的修改很有必要，感谢贡献！ 另外这份文档很久没人动过了，你如果有兴趣的话可以试试对它做一次大修，我帮你 review. |

顺便我就是 NixOS & Flakes Book 的作者，其实之前我也写过一份很简单的 Nix 语言入门教程，但是有人反馈说对新手不太友好，而且我确实也写得比较简略，所以后面才改成推荐阅读这一份。 |

可以的，我向来对这种事感兴趣，可以边学边做。预计两周内能够完成。
我知道的，谢谢你写的指南，能在这里看到你我也感到惊喜与荣幸。 |

作用
让 Nix 新手更容易理解这份教程。
背景
我第一次尝试学习 Nix 时使用的资料是 NixOS & Flakes Book，其中Nix 语言入门提到：
打开这个页面后，交互模式还好，但是当我读到下面这句
我完全无法理解：匿名集合在这里指的是什么？a 集合又指的是什么？
即使我打算暂时放下问题，读读接下来的段落，或许就能理解前面的问题了，但完全不行，疑惑甚至越来越多了。
以上所述的入门失败大概已经是一年前的事了。
前不久我打算再次挑战 Nix 入门，这次我选择的教程是 Evertras/simple-homemanager，并且顺利地阅读到了结尾。只不过，它的内容深度有限，稍微深入的内容还是需要其它资源。
于是我再次想起了《Nix 语言快速入门》，而这次我终于能理解它在说什么了，并且也明白了对于真正的 Nix 新手来说，它所缺少的基础知识是什么，于是就有了这个 PR。
