Step 1: Download and Install Cursor (第一步：下载和安装)

Cursor is available for macOS (Intel and Apple Silicon), Windows (x64 and ARM), and Linux (AppImage, .deb). The installer detects your existing VS Code installation and offers to import settings, extensions, themes, and keybindings with a single click. No manual configuration is required.

English: Installation Guide

Visit the Cursor download page and select your operating system. The download starts automatically. On macOS, drag the app to Applications. On Windows, run the .exe installer. On Linux, use the AppImage or install the .deb package. When Cursor launches for the first time, it prompts you to import VS Code settings — click "Import" to transfer everything. Create a free account with email or GitHub OAuth to activate the Hobby plan immediately. No credit card is required. Students with a .edu email can claim one year of Cursor Pro for free.

中文：安装指南

访问Cursor下载页面，选择您的操作系统。macOS用户将应用拖到"应用程序"文件夹。Windows用户运行.exe安装程序。Linux用户可以使用AppImage或安装.deb包。首次启动时，Cursor会提示导入VS Code设置——点击"Import"即可一键迁移所有设置、扩展和快捷键。使用邮箱或GitHub OAuth创建免费账户，立即激活Hobby计划。无需信用卡。持.edu邮箱的学生可免费获得一年Cursor Pro。

Step 2: Master Tab Completion (第二步：掌握Tab补全)

Tab completion is the feature you will use most frequently in Cursor. Unlike traditional autocomplete that suggests single tokens, Cursor predicts entire multi-line edits based on your current context — imports, function signatures, surrounding code patterns, and project conventions.

How Tab Completion Works

As you type, Cursor's AI model analyzes your codebase context and generates inline suggestions displayed in gray text. Press Tab to accept the full suggestion, Escape to dismiss it, or Ctrl+Right Arrow to accept word-by-word. The completion engine uses frontier models including Claude Sonnet and GPT-5.4, with auto mode selecting the fastest model that meets the complexity threshold. On the Pro plan, Tab completions are unlimited and consume zero credits.

Tab补全是Cursor最常用的功能。它不仅预测下一个单词，还能预测整个代码块。按Tab接受建议，按Escape取消，按Ctrl+右箭头逐词接受。Pro计划中Tab补全无限使用且不消耗额度。

Tab Completion Best Practices

Write clear function names and type annotations — the model uses these as signals. Add a brief comment above a function describing its purpose and Cursor generates the implementation. Keep files well-organized with descriptive imports so the context window captures relevant code. For complex logic, write the first line of a block and let Tab complete the rest. The model adapts to your coding style over time. According to Cursor's documentation, developers accept approximately 40% of Tab suggestions in daily usage.

Step 3: Use Composer for Multi-File Editing (第三步：使用Composer)

Composer lets you describe a change in natural language and apply it across multiple files simultaneously. This is the feature that fundamentally changes how developers interact with their codebase — instead of editing files one at a time, you describe the outcome and Composer handles the implementation.

Composer Workflow

Open Composer with Ctrl+Shift+I (or Cmd+Shift+I on macOS). Type your instruction: "Add input validation to the user registration form with email format check, password strength requirements, and error messages." Composer analyzes your project structure, identifies the relevant files, generates the changes, and presents a diff preview. Review each change, accept or reject individual hunks, and apply when ready. Composer handles imports, type definitions, test files, and configuration updates automatically.

Composer使用技巧

使用Composer时，描述要尽可能具体。不要只说"添加验证"，而是说"添加邮箱格式验证、密码强度检查（至少8个字符，包含大写字母和数字）、以及中英文错误提示"。Composer会分析项目结构，找到相关文件，生成更改并显示diff预览。您可以逐个接受或拒绝修改。Composer自动处理导入语句、类型定义和配置更新。与Agent模式结合使用效果更佳。

Step 4: Activate Agent Mode (第四步：启动Agent模式)

Agent mode is Cursor's most powerful feature. It autonomously writes code, creates files, runs terminal commands, installs packages, executes tests, and iterates on errors until the task is complete. Agent mode transforms Cursor from a code editor into a coding partner that executes multi-step workflows independently.

Agent Mode Tutorial

Switch to agent mode in the chat panel dropdown. Describe your task with specificity: "Build a REST API for the task model with CRUD endpoints, input validation, error handling, unit tests, and database migration." Agent mode plans the implementation, creates each file, writes the code, runs the development server, tests the endpoints, and fixes any errors it encounters. Each step is visible in the chat panel. You can pause at any point, modify the plan, or take over manually. Agent mode uses your monthly credit pool — monitor usage in Settings.

Agent模式教程

在聊天面板下拉菜单中切换到Agent模式。具体描述您的任务。Agent模式会规划实现方案、创建文件、编写代码、运行服务器、测试端点并修复遇到的错误。每个步骤都在聊天面板中可见。您可以随时暂停、修改计划或手动接管。Agent模式使用月度额度池。Pro计划提供$20额度，Pro+提供$60额度，Ultra提供$200额度。对于需要频繁使用Agent模式的开发者，建议选择Pro+或Ultra计划。

Step 5: Explore Codebase Chat and Advanced Features

Beyond Tab completion, Composer, and agent mode, Cursor offers @codebase chat for asking questions about your entire project, Cursor Rules for project-level AI configuration, and MCP servers for connecting external tools. These features work together to create a development environment where AI understands your specific project context.

@Codebase Chat

@codebase indexes every file in your project. Ask "how does the authentication middleware work?" or "where is the database connection configured?" and Cursor searches your entire codebase for context-aware answers. No need to manually copy-paste file contents. Type @ followed by a filename to reference specific files in your questions. 使用@codebase可以询问整个项目的问题，无需手动复制粘贴代码。

Cursor Rules

Cursor Rules define how AI behaves in your project. Create a .cursorrules file specifying coding conventions ("use TypeScript strict mode"), patterns ("repository pattern for data access"), and response preferences. Rules persist across sessions. Research from Stanford CS shows that project-level AI configuration reduces code review iterations by 30%.

MCP Servers

MCP servers connect Cursor to external tools — databases, APIs, documentation, deployment pipelines. The AI reads data from MCP servers to generate more accurate code. Query your production database schema, fetch API docs, or check deployment status from within the Cursor editor without switching windows.

Cursor使用教程常见问题 — Frequently Asked Questions

Answers to common questions about using Cursor, covering both English and Chinese developer queries about the AI code editor tutorial.

Cursor使用教程从哪里开始？(Where do I start with the Cursor tutorial?)

Start by downloading Cursor from the official site. The installer imports your existing VS Code settings, extensions, and keybindings automatically. Once installed, open any project folder and begin coding — Tab completions activate immediately. For Chinese-language resources, this guide covers each feature with bilingual explanations. 下载Cursor后，安装程序会自动导入您的VS Code设置。打开任何项目文件夹即可开始使用AI功能。

Is there a Chinese version of Cursor?

Cursor's interface is in English, but it fully supports Chinese-language code comments, documentation, and chat prompts. You can write prompts to Composer and agent mode in Chinese and receive Chinese-language responses. The AI models (Claude, GPT, Gemini) all support multilingual input and output.

Cursor Pro值得购买吗？(Is Cursor Pro worth it?)

Cursor Pro at $20/month provides unlimited Tab completions and a $20 monthly credit pool for premium AI models. For developers coding daily, the productivity gains from Tab completions alone typically save 1-2 hours per day. Pro+ at $60/month suits heavy agent mode users. See full pricing for all tiers. 对于每天编码的开发者，仅Tab补全功能每天就能节省1-2小时。

How do I use Cursor agent mode effectively?

Agent mode works best with clear, specific task descriptions. Instead of "build a login page," write "create a React login component with email/password fields, form validation, JWT authentication API call, error handling, and a redirect to /dashboard on success." Agent mode plans the implementation, creates files, writes code, runs tests, and iterates on errors. Monitor each step in the chat panel and intervene when needed. Read the official documentation for advanced agent configuration.
