How to Use Cursor for Code Completion in 30 Minutes

If you’re a solo founder or indie hacker who's ever spent hours wrestling with code, you know that time is your most precious resource. That's where Cursor comes in. This AI coding tool promises to speed up your development process with smart code completion. In this guide, I'll walk you through how to set it up and make the most of it in just 30 minutes.

Prerequisites: What You Need

Before diving in, ensure you have the following:

• Cursor installed: Visit Cursor’s website and download the latest version. As of April 2026, Cursor is still free to use.
• Basic coding knowledge: Familiarity with at least one programming language (JavaScript, Python, etc.) will help you get the most out of Cursor.
• A code editor: You can use any code editor, but Cursor works seamlessly with VS Code.

Step 1: Download and Install Cursor

1. Go to the Cursor download page.
2. Choose your operating system (Windows, macOS, or Linux).
3. Follow the installation instructions for your OS.
4. Once installed, open Cursor and create an account if prompted.

Expected output: You should see a welcome screen with a prompt to start coding.

Step 2: Connect Cursor to Your Code Editor

1. Open your preferred code editor (VS Code recommended).
2. In VS Code, navigate to the Extensions view (Ctrl+Shift+X).
3. Search for "Cursor" and install the Cursor extension.
4. After installation, restart VS Code.

Expected output: Cursor should now be integrated, visible in the sidebar.

Step 3: Start Coding with Cursor

1. Open a new file or an existing project in your code editor.
2. Start typing your code. Cursor will automatically suggest completions as you type.
3. Use the arrow keys to navigate through suggestions and hit Enter to select one.

Expected output: Cursor should complete your code based on the context, speeding up your workflow.

Step 4: Fine-Tune Cursor Settings

1. In the Cursor sidebar, click on "Settings."
2. Adjust preferences like suggestion delay (default is 250ms) and theme (light/dark).
3. Explore advanced settings to customize how Cursor interacts with your code.

Expected output: Your coding experience should feel more personalized and efficient.

Troubleshooting: What Could Go Wrong

• Cursor doesn’t suggest completions: Ensure you’re connected to the internet and have the latest version installed.
• Suggestions are irrelevant: Make sure you’re coding in a recognized language. Cursor excels at languages like JavaScript and Python.

What's Next: Level Up Your Coding

Once you’re comfortable with the basics of Cursor, consider exploring its advanced features:

• Custom snippets: Create your own snippets for repetitive code.
• Integrations: Check out integrations with other tools like GitHub for seamless version control.
• Community resources: Join the Cursor community to share tips and learn from other users.

Conclusion: Start Here

Cursor can significantly enhance your coding efficiency, especially if you’re working on side projects or indie startups. Start by installing it and integrating it into your workflow. Within 30 minutes, you’ll be on your way to faster coding with smarter suggestions.

What We Actually Use

In our experience at Built This Week, we primarily use Cursor for quick coding tasks and prototyping. It works well for smaller projects but can slow down with larger codebases, so keep that in mind as you scale.
