How to Use GitHub Copilot for Faster Coding: A 15-Minute Tutorial

If you're a solo founder or indie hacker, you know that coding can take a lot of time—time that could be spent building your product or finding customers. Enter GitHub Copilot, an AI-powered coding assistant that can help you write code faster. But how do you actually harness its power? In this quick tutorial, I’ll walk you through using GitHub Copilot effectively in just 15 minutes.

Prerequisites

Before we dive into the tutorial, here’s what you’ll need:

• A GitHub account (free)
• Visual Studio Code (VS Code) installed
• GitHub Copilot subscription ($10/month or $100/year as of February 2026)

Step 1: Setting Up GitHub Copilot

1. Install the GitHub Copilot Extension:

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

2. Sign In to GitHub:

   • After installation, you’ll be prompted to sign in to your GitHub account. Follow the authentication steps.

3. Enable Copilot:

   • Once signed in, Copilot should be automatically enabled. You can check under the Extensions menu.

Step 2: Writing Code with Copilot

1. Start Typing Your Code:

   • Open a new file in your preferred programming language (e.g., JavaScript, Python).
   • Begin typing a comment that describes the function you want to create. For example:

     // Function to calculate the factorial of a number
     

2. Review Suggestions:

   • As you type, GitHub Copilot will provide suggestions. You can scroll through these using the arrow keys and hit Tab to accept a suggestion.

3. Refine Your Code:

   • If the initial suggestion isn’t quite right, you can continue typing to refine it, and Copilot will adjust its suggestions accordingly.

Step 3: Testing and Iterating

1. Run Your Code:

   • After accepting a suggestion, run the code to see if it works as expected. If not, you can adjust the input and ask Copilot for help again.

2. Debugging with Copilot:

   • If you encounter any errors, you can ask Copilot to help debug. For example, type:

     // Fix the error in this function
     

3. Iterate:

   • Use Copilot’s suggestions to improve and expand your code. You can build out functions or entire classes just by describing what you want in comments.

Troubleshooting Common Issues

• Copilot Isn’t Suggesting Code: Make sure you’re signed in and that the extension is enabled in VS Code.
• Suggestions Aren’t Relevant: Try being more specific in your comments. The better your prompt, the better Copilot’s suggestions.
• Performance Issues: If VS Code is lagging, try disabling other extensions or restarting the editor.

What's Next?

Now that you know how to use GitHub Copilot, consider exploring these features:

• Pair Programming: Use Copilot to act as a coding partner, helping you brainstorm solutions.
• Learning New Languages: If you’re venturing into a new programming language, Copilot can suggest idiomatic patterns that may not be immediately familiar to you.

Conclusion

If you’re looking to speed up your coding process, GitHub Copilot is an excellent tool to add to your arsenal. With just a bit of setup, you can dramatically reduce the time it takes to write and debug code. Start by installing the extension and following the steps above to get your first lines of code written in no time.

What We Actually Use

We primarily use GitHub Copilot for writing boilerplate code and generating function prototypes. While it’s not perfect and requires some oversight, it significantly speeds up our initial coding phase.
