Module 3: Nano Banana3.0: Setup & Download

Nano Banana Pro for Product Managers

3.0: Setup & Download

  • Time to Complete: 5 minutes
  • Prerequisites: Claude Code installed, 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 Claude Code course.

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

  • 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 course, 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 Claude Code that compounds over time. The workflow matters as much as the output.

Before You Start

You’ll need:

  • Claude Code installed and working
  • A Google account
  • A payment method for Google Cloud billing

About cost: Gemini 3 Pro charges ~$0.10 per image. The entire course costs less than $5 total. Claude will walk you through setting up billing in the first module.

Download fails

Try downloading manually from the release page and extracting to your Documents folder.

Claude Code doesn’t recognize /start commands

Make sure you’re running Claude Code from inside the claude-code-pm-course folder. The slash commands only work when Claude has access to the module files.

What’s Next?

Once Claude Code is running inside the claude-code-pm-course folder:

Type: /start-3-1-1

Claude 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.
