How to Use GitHub Copilot to Write Code Faster: A 30-Minute Guide

If you’re a solo founder or indie hacker, you know how precious time is. Writing code can be a slow and tedious process, especially when you’re juggling multiple responsibilities. Enter GitHub Copilot: an AI-powered code assistant designed to speed up your coding workflow. In this guide, I’ll show you how to set up and use GitHub Copilot to write code faster, all in about 30 minutes.

Time Estimate: 30 Minutes

You can finish this setup in about 30 minutes if you follow the steps closely.

Prerequisites

1. GitHub Account: You need an account to access Copilot.
2. Visual Studio Code: The most popular IDE where Copilot integrates seamlessly.
3. GitHub Copilot Subscription: As of August 2026, it costs $10/month after a 30-day free trial.

Step-by-Step Setup

1. Install Visual Studio Code

Download and install Visual Studio Code (VS Code) from here. It’s free and works on all major operating systems.

2. Sign Up for GitHub Copilot

• Go to the GitHub Copilot page.
• Click on "Try Copilot" and log in with your GitHub account.
• Start your 30-day free trial. If you decide to continue, it will be $10/month.

3. Install the Copilot Extension

• Open VS Code.
• Go to the Extensions view by clicking on the Extensions icon in the Activity Bar on the side of the window.
• Search for "GitHub Copilot" and click on "Install."

4. Enable Copilot

After installation, you might need to enable GitHub Copilot in your workspace settings. Go to:

• File > Preferences > Settings (or Code > Preferences > Settings on macOS).
• Search for "Copilot" and ensure it's enabled.

5. Start Coding

Now you’re ready to use Copilot! Here’s how to make the most of it:

• Write Comments: Start by writing a comment describing what you want the code to do. For example, // Function to fetch user data.
• Accept Suggestions: As you type, Copilot will suggest code. You can accept suggestions by pressing Tab or reject them with Esc.
• Iterate: If the first suggestion isn’t perfect, keep typing or modify your comment for a better result.

Example Output

Let’s say you write:

// Function to calculate the Fibonacci series

Copilot might suggest:

function fibonacci(n) {
  let a = 0, b = 1, temp;
  while (n-- > 0) {
    temp = a;
    a = b;
    b = temp + b;
  }
  return a;
}

Troubleshooting Common Issues

• No Suggestions: If Copilot isn’t suggesting code, make sure you’re connected to the internet and that your subscription is active.
• Slow Performance: Sometimes, Copilot can lag. Restarting VS Code usually helps.

What’s Next?

Once you’re comfortable using GitHub Copilot, consider exploring its advanced features, such as:

• Multi-line suggestions: Type a few lines and see how Copilot can complete functions for you.
• Language Support: Copilot supports multiple programming languages, so try it out with Python, Java, or even HTML/CSS.

Conclusion

GitHub Copilot can significantly speed up your coding process, allowing you to focus on building your product rather than getting bogged down in syntax. Start with the setup we discussed, and soon, you’ll find yourself coding faster and more efficiently.

If you’re just getting started with Copilot, I recommend focusing on simple tasks to see how it can assist you. As you gain confidence, you can tackle more complex coding challenges.
