Concept Explained
A prompt is the instruction you give Gemini. Gemini reads it, generates a response, and you decide whether to accept, refine, or reject.
How It Works
Type your prompt. Press Enter. Gemini generates a response. If good, use it. If not, refine and try again.
Step-by-Step Tutorial
1. Type a simple prompt
Try: Explain what an API is in 3 sentences.2. Read critically
Did Gemini answer the question? Right tone? Right length?3. Refine if needed
If too long: in 2 sentences. If too technical: for a non-technical audience.4. Try creative
Write a 4-line haiku about autumn.5. Try reasoning
If I have 5 apples and give 2 to a friend, then buy 3 more, how many do I have?Real-World Example
A new user's first prompt was tell me about AI. Gemini produced a 500-word essay. The user was overwhelmed. Lesson: first prompts should be specific and short.
Example Prompts / Commands / Code
# Bad (vague):
"Tell me about AI."
# Better (specific):
"In 3 bullet points, what are the main types of AI?"
# Even better (specific + audience):
"For a non-technical manager, in 3 bullet points, what are the main types of AI?"
Common Mistakes
