# 基金会来信

## 致谢

你好，欢迎阅读 2018 年 5/6 月刊的 FreeBSD 期刊。

不是通常的基金会更新，我们想花一分钟说声谢谢！

2018 年 6 月 19 日是 FreeBSD 项目 25 周年纪念。没有你——FreeBSD 社区——我们无法达到这个历史性里程碑。从在 UC Berkeley 的微小起步，到如今被大公司和个人广泛使用、受人尊敬的开源操作系统，你对项目的热情和奉献是其长寿和增长的原因。我们希望你在 6 月 19 日和今年余下时间加入我们庆祝 FreeBSD。

# 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/journal/20180506-an-quan/foundation-letter.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.
