+# 第一章 简介
+
+本课程由哈里森·蔡斯 (Harrison Chase，LangChain作者）与Deeplearning.ai合作开发，课程将介绍如何使用LangChain和自有数据进行对话。
+
+
+## 一、背景
+大语言模型(Large Language Model, LLM), 比如ChatGPT, 可以回答许多不同的问题。但是大语言模型的知识来源于其训练数据集，并没有用户的信息（比如用户的个人数据，公司的自自有数据），也没有最新发生时事的信息（在大模型数据训练后发表的文章或者新闻）。因此大模型能给出的答案比较受限。
+
+如果能够让大模型结合已有信息和自有数据中的信息来进行对话，回答我们的问题，那我们便能够得到更好的答案。
+
+
+## 二、 课程基本内容
+
+在本课程中，我们学习如何使用LangChain和自有数据进行对话。
+
+LangChain是用于构建大模型应用程序的开源框架，有Python和JavaScript两个不同版本的包。LangChain基于模块化组合，有许多单独的组件，可以一起使用或单独使用。LangChain的组件包括：
+
+- 提示(Prompts): 使模型执行操作的方式
+- 模型(Models)：大语言模型、对话模型，文本表示模型。目前包含多个模型的集成。
+- 索引(Indexes): 获取数据的方式，可以与模型结合使用
+- 链式(Chains): 端到端功能实现
+- 代理(Agents): 使用模型作为推理引擎
+
+此外LangChain还拥有很多应用案例，帮助我们了解如何将这些模块化组件以链式方式组合，以形成更多端到端的应用程序 。
+
+如果你想要了解关于LangChain的基础知识，可以学习使用 LangChain 开发基于 LLM 的应用程序课程（LangChain for LLM Application Development）。

+# Blendle's Employee Handbook
+
+This is a living document with everything we've learned working with people while running a startup. And, of course, we continue to learn. Therefore it's a document that will continue to change. 
+
+**Everything related to working at Blendle and the people of Blendle, made public.**
+
+These are the lessons from three years of working with the people of Blendle. It contains everything from [how our leaders lead](https://www.notion.so/ecfb7e647136468a9a0a32f1771a8f52?pvs=21) to [how we increase salaries](https://www.notion.so/Salary-Review-e11b6161c6d34f5c9568bb3e83ed96b6?pvs=21), from [how we hire](https://www.notion.so/Hiring-451bbcfe8d9b49438c0633326bb7af0a?pvs=21) and [fire](https://www.notion.so/Firing-5567687a2000496b8412e53cd58eed9d?pvs=21) to [how we think people should give each other feedback](https://www.notion.so/Our-Feedback-Process-eb64f1de796b4350aeab3bc068e3801f?pvs=21) — and much more.
+
