While AI plugins have existed for code editors for years, Cursor took a radically different approach: they forked the open-source VS Code editor to rebuild the interaction model around full repository intelligence and predictive next-action completions.

Step-by-Step Instructions

1

Import Your Existing VS Code Setup

Download Cursor, run the onboarding wizard, and select 'Import Extensions and Keybindings' from your existing VS Code installation.

2

Index Your Project Codebase

Open your project folder, navigate to Settings > Features > Codebase Indexing, and wait 30 seconds for embeddings to complete.

3

Master In-Line Code Generation (Ctrl+K)

Highlight any function or CSS block, press Ctrl/Cmd + K, type your instructions, and accept or reject the colored diff.

Use .cursorrules File

Add a .cursorrules file to your project root to enforce coding standards, naming conventions, and preferred CSS architectures across all team prompts.
