🚀 60-Second Quickstart (Start Here)

If you have never used an AI coding tool before, start here:

1. What is it? An AI coding assistant is like an expert pair programmer sitting beside you. It predicts your next line of code (ghost text), answers technical questions about your project, and writes boilerplate functions.
2. The 3-Step Setup:
   • Step 1: Download Cursor (a pre-configured editor) or install the Codeium / Continue.dev extension in your existing VS Code.
   • Step 2: Open any code file and start typing. Press Tab whenever grey ghost text appears to accept suggestions.
   • Step 3: Highlight any confusing function and press Ctrl+L (or Cmd+L) to ask: "Explain what this code does in plain English."

🌱 Level 1: Beginner (Plug-and-Play & In-Editor)

Zero configuration required. Install and start coding within 2 minutes.
