-MaxKB = Max Knowledge Base，是一款基于大语言模型和 RAG 的开源知识库问答系统，广泛应用于企业内部知识库、客户服务、学术研究与教育等场景。
+MaxKB = Max Knowledge Brain, it is an open-source platform for building enterprise-grade agents. MaxKB integrates Retrieval-Augmented Generation (RAG) pipelines, supports robust workflows, and provides advanced MCP tool-use capabilities. MaxKB is widely applied in scenarios such as intelligent customer service, corporate internal knowledge bases, academic research, and education.
 
-- **开箱即用**：支持直接上传文档、自动爬取在线文档，支持文本自动拆分、向量化、RAG（检索增强生成），智能问答交互体验好；
-- **模型中立**：支持对接各种大语言模型，包括本地私有大模型（Llama 3 / Qwen 2 等）、国内公共大模型（通义千问 / 智谱 AI / 百度千帆 / Kimi / DeepSeek 等）和国外公共大模型（OpenAI / Azure OpenAI / Gemini 等）；
-- **灵活编排**：内置强大的工作流引擎，支持编排 AI 工作过程，满足复杂业务场景下的需求；
-- **无缝嵌入**：支持零编码快速嵌入到第三方业务系统，让已有系统快速拥有智能问答能力，提高用户满意度。
+- **RAG Pipeline**: Supports direct uploading of documents / automatic crawling of online documents, with features for automatic text splitting, vectorization. This effectively reduces hallucinations in large models, providing a superior smart Q&A interaction experience.
+- **Agentic Workflow**: Equipped with a powerful workflow engine, function library and MCP tool-use, enabling the orchestration of AI processes to meet the needs of complex business scenarios. 
+- **Seamless Integration**: Facilitates zero-coding rapid integration into third-party business systems, quickly equipping existing systems with intelligent Q&A capabilities to enhance user satisfaction.
+- **Model-Agnostic**: Supports various large models, including private models (such as DeepSeek, Llama, Qwen, etc.) and public models (like OpenAI, Claude, Gemini, etc.).
+- **Multi Modal**: Native support for input and output text, image, audio and video.
 
-## 快速开始
+## Quick start
 
-```
-docker run -d --name=maxkb --restart=always -p 8080:8080 -v ~/.maxkb:/var/lib/postgresql/data -v ~/.python-packages:/opt/maxkb/app/sandbox/python-packages cr2.fit2cloud.com/1panel/maxkb
+Execute the script below to start a MaxKB container using Docker:
 
-# 用户名: admin
-# 密码: MaxKB@123..
+```bash
+docker run -d --name=maxkb --restart=always -p 8080:8080 -v ~/.maxkb:/var/lib/postgresql/data -v ~/.python-packages:/opt/maxkb/app/sandbox/python-packages 1panel/maxkb
 ```
 
-- 你也可以通过 [1Panel 应用商店](https://apps.fit2cloud.com/1panel) 快速部署 MaxKB + Ollama + Llama 3，30 分钟内即可上线基于本地大模型的知识库问答系统，并嵌入到第三方业务系统中；
-- 如果是内网环境，推荐使用 [离线安装包](https://community.fit2cloud.com/#/products/maxkb/downloads) 进行安装部署；
-- 你也可以在线体验：[DataEase 小助手](https://dataease.io/docs/v2/)，它是基于 MaxKB 搭建的智能问答系统，已经嵌入到 DataEase 产品及在线文档中；
-- MaxKB 产品版本分为社区版和专业版，详情请参见：[MaxKB 产品版本对比](https://maxkb.cn/pricing.html)。
