🎯 Initial Setup and Configuration

First Launch Experience

When you first launch Cursor, you’ll see a welcome screen with several options:

1. Sign up/login - Create an account or sign in with GitHub
2. Import settings - Migrate from VS Code if desired
3. Choose theme - Select your preferred color scheme
4. Install extensions - Add your favorite VS Code extensions

Essential Settings to Configure

Open Settings (Cmd/Ctrl + ,) and configure these key options:

{
  "cursor.chat.enabled": true,
  "cursor.completion.enabled": true,
  "cursor.inline.enabled": true,
  "editor.fontFamily": "JetBrains Mono, Consolas, monospace",
  "editor.fontSize": 14,
  "workbench.colorTheme": "Cursor Dark"
}

💬 Using the AI Chat Feature

The AI chat is Cursor’s flagship feature. Here’s how to make the most of it:

Accessing Chat

There are multiple ways to open the chat panel:

• Keyboard Shortcut: Cmd/Ctrl + L
• Command Palette: Cmd/Ctrl + Shift + P, then type “Chat”
• Sidebar: Click the chat icon in the activity bar

Basic Chat Commands

1. Code Explanation

Explain what this function does:

function calculateTotal(items) {
  return items.reduce((sum, item) => sum + item.price * item.quantity, 0);
}

2. Code Generation

Create a React component for a user profile card with:
- User avatar
- Name and email
- Edit button
- Responsive design

3. Debugging Help

I'm getting this error: "Cannot read property 'map' of undefined"
Here's my code:
const users = data.users;
return users.map(user => <div>{user.name}</div>);

4. Code Refactoring

Refactor this code to use async/await instead of .then():
fetch('/api/users')
  .then(response => response.json())
  .then(data => console.log(data))
  .catch(error => console.error(error));

Advanced Chat Features

Context-Aware Suggestions

Cursor understands your project context. Try these prompts:

// Based on my current React project
Add TypeScript types to this component and fix any type errors

// For API projects
Create proper error handling for this Express.js route

// For styling
Convert these inline styles to CSS modules

Multi-File Operations

Create a new utility file called 'helpers.js' and move these functions there, then update all imports

🪝 Practical Examples and Use Cases

Example 1: Building a Todo App

Prompt:

Create a complete todo app with:
- Add new todos
- Mark as complete/incomplete
- Delete todos
- Filter by status
- Local storage persistence
- Modern UI with Tailwind CSS

Expected Result: Cursor will generate multiple files including the main component, utilities, and styling.

Example 2: API Integration

Prompt:

I need to integrate with the OpenWeather API. Create:
- API service module
- Error handling
- Loading states
- TypeScript interfaces
- Component to display weather data

Example 3: Database Setup

Prompt:

Set up a PostgreSQL database schema for a blog platform with:
- Users table
- Posts table
- Comments table
- Categories table
- Proper relationships and indexes
