The Nano Banana Basic Prompt Engineering Guide starts with understanding that a prompt is a key tool for interacting with AI models. It's the instruction or question you send to the AI, which determines the quality and accuracy of the AI's response.

A good prompt should have the following characteristics according to the Nano Banana Basic Prompt Engineering Guide:

• Clear and specific: Avoid vague expressions

• Detailed: Provide sufficient context information

• Structured: Use reasonable format and organization

The Nano Banana Basic Prompt Engineering Guide emphasizes that mastering these fundamentals is essential for effective AI communication.

The Nano Banana Basic Prompt Engineering Guide teaches that basic prompts usually contain the following parts:
