3.0: Setup

• Time to Complete: 5 minutes
• Prerequisites: Course set up in Cursor (Module 0), Google account

What is Nano Banana?

Nano Banana teaches you to generate professional images using Gemini 3 Pro Preview (codenamed “Nano Banana Pro”) - Google’s most advanced image generation model. But this isn’t just a course about prompting an image generator.

This is a Cursor course.

You’ll learn to build a complete image generation workflow where Cursor:

• Runs your generations - Execute image requests directly from your terminal
• Batches multiple images - Generate variants and iterations in parallel
• Manages your files - Organize outputs, name them intelligently, track versions
• Builds your style library - Create and maintain reusable style definitions
• Iterates with you - Refine prompts, adjust parameters, and improve results conversationally

By the end of this module, you’ll be able to create:

• Persona portraits and lifestyle shots
• Journey maps and user flow visualizations
• Wireframes and device mockups
• Architecture diagrams and strategy frameworks
• Marketing assets and launch graphics

Key insight: You’re not just learning to generate images - you’re building a professional creative pipeline powered by Cursor that compounds over time. The workflow matters as much as the output.

Before You Start Module 3

You’ll need:

• A payment method for Google Cloud billing

What You’ll Learn

Module 3.1: Introduction to Image Generation

• 3.1.1: Welcome & First Generation - Set up your API key and generate your first image

Troubleshooting

Slash commands don’t appear

Make sure you’re running Cursor from your course folder (not a subfolder). The slash commands only work when Cursor has access to the .cursor/commands/ directory.

”Module not found” error

You may have an older version of the course. In the Agents view, ask the AI to update the course to the latest version — the update includes Nano Banana.

What’s Next?

Type: /start-3-1-1 in the Agents view

The AI will guide you through:

• Getting your Gemini API key
• Setting up billing
• Generating your first image

The entire setup takes about 5 minutes, and you’ll have your first AI-generated image before you know it.
