# 第一版（2001）

第二版是 FreeBSD 文档项目敬业成员两年多工作的成果。本版的主要变化如下：

* 添加了完整索引。
* 所有 ASCII 图均由图形化的图表取代。
* 每章都增加了标准概述，快速概述该章包含的信息以及读者应了解的内容。
* 内容按逻辑重组为三部分：“快速开始”、“系统管理”和“附录”。
* [FreeBSD 基础](/handbook/di-3-zhang-freebsd-ji-chu/3.1.-gai-shu.md)扩充了，包含了有关进程、守护进程和信号的额外信息。
* [安装应用程序：软件包和 Ports](/handbook/di-4-zhang-an-zhuang-ying-yong-cheng-xu-ruan-jian-bao-he-ports/4.1.-gai-shu.md)扩充了，包含了有关二进制软件包管理的额外信息。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://book.bsdcn.org/handbook/qian-yan/di-yi-ban-2001.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
