How to Use GitHub Copilot in VS Code: A Beginner's Guide

Introduction

GitHub Copilot is the AI assistant most new developers try first, and VS Code is where most of them use it. The two fit together naturally, since Copilot began as a VS Code extension. Getting started takes only a few minutes.

The goal of this guide is to get you from a blank editor to productive use without confusion. It covers installation, the core features, and the habits that make Copilot help rather than hurt your learning.

This is written for beginners as of mid-2026. You do not need prior experience with AI tools, only a GitHub account and a working copy of VS Code on your machine.

Quick Answer

To use Copilot in VS Code, install the official Copilot extension from the Marketplace, sign in with your GitHub account, and start typing. Grayed-out suggestions appear as you write, and pressing Tab accepts them.

For anything more than autocomplete, open the Copilot chat panel. There you can ask questions, request rewrites, and have code explained in plain language. Both features live inside the editor, so you never break your flow.

What to Look For

Before diving in, it helps to know what a good setup looks like. The points below keep you from common beginner mistakes. Treat them as a checklist while you get oriented.

A Signed-In GitHub Account

Copilot requires a GitHub account and an active plan or free-tier access. Signing in is what unlocks suggestions. Without it, the extension installs but stays inactive.

The Right Extension

Search the Marketplace for the official GitHub Copilot extension published by GitHub. Installing the correct one avoids look-alikes and ensures you get chat and completions. The publisher name is your best signal.

A Supported Editor Version

Keep VS Code reasonably up to date, since Copilot features track recent releases. An outdated editor can miss chat or newer capabilities. Updating takes a minute and prevents confusing gaps.

Clear Expectations

Copilot suggests; it does not decide. Knowing that up front keeps you reading suggestions instead of trusting them blindly. That mindset is the single biggest factor in learning well with it.

How to Set It Up

Start by opening VS Code and going to the Extensions panel. Search for GitHub Copilot, confirm the publisher is GitHub, and install it. The chat companion often installs alongside it or as a related extension.

Next, sign in. A prompt appears asking you to authorize the extension with your GitHub account, following the steps on the official Copilot page. Complete the browser sign-in, and VS Code links to your account automatically.

Once signed in, open any code file and begin typing. Within a moment you should see grayed-out suggestions ahead of your cursor. Press Tab to accept a suggestion, or keep typing to ignore it.

To use chat, open the Copilot chat view from the sidebar or command palette. From there you can ask questions about your code, request explanations, or ask for a rewrite of a selected block.

If suggestions do not appear, check a few common causes. Confirm you are signed in, that the file type is supported, and that Copilot is enabled for the current language. A quick editor restart often clears a stuck session.

You can also tune how Copilot behaves. The extension settings let you enable or disable inline suggestions per language and toggle features you do not want. Beginners usually leave the defaults on until they know what to change.

Feature Comparison

The table below summarizes Copilot’s main features in VS Code and when each one helps. It is a practical overview, not an exhaustive reference.

Feature	What It Does	Best Used For
Inline completions	Suggests code as you type	Boilerplate and syntax recall
Copilot chat	Answers questions in context	Explaining and debugging code
Comment prompts	Turns comments into code	Sketching a function quickly
Code selection edits	Rewrites highlighted code	Refactoring small blocks

The pattern is clear across rows. Completions keep you moving, and chat helps you understand.

For a beginner, the explanation features often matter more than raw speed. A faster wrong answer teaches nothing.

How to Choose Your Workflow

Decide early how much you want to rely on suggestions. A healthy starting rule is to read every suggestion before accepting it. That single habit keeps Copilot from writing code you cannot explain.

Use chat as a tutor, not just a fixer. When an error appears, ask what it means before asking for the fix. Understanding the cause is what turns a bug into a lesson.

Let comments guide the tool. Writing a short comment describing what you want often produces a cleaner suggestion. This also forces you to think through the problem first.

Keep occasional practice sessions with completions turned off. New to AI tools? Our Claude Code setup guide covers the same review-first mindset.

Pricing: What to Expect

Copilot has typically offered a free tier with usage caps, individual paid plans with higher limits, and free access for verified students through GitHub Education. Exact quotas and eligibility have changed several times and likely will again.

For beginners, the practical takeaway is that trying Copilot costs nothing. Between the free tier and student verification, you can use the real product long enough to judge its value.

This guide avoids quoting specific prices because they change faster than articles do. Always confirm current plans, caps, and student eligibility on the official GitHub pricing and education pages before deciding.

Conclusion

Using GitHub Copilot in VS Code is straightforward: install the extension, sign in, and start typing. The setup takes minutes, and the core features reveal themselves quickly once suggestions begin to appear.

The difference between helpful and harmful use comes down to habits. Read before you accept, ask chat to explain rather than just fix, and practice without it now and then to keep your skills sharp.

Set up this way, Copilot becomes a genuine learning aid inside an editor you already know. Get the habits right early, and the tool speeds you up without slowing your growth.
