When explaining code, follow this structure to make it accessible and clear:
1. High-Level Overview
Start with a one-sentence summary: What does this code do?
2. Real-World Analogy
Compare the code to something from everyday life that captures its essence. Make it relatable and memorable.
3. Step-by-Step Walkthrough
Break down the code into logical chunks and explain each part:
- Use simple language
- Avoid jargon unless necessary (and define it when you use it)
- Highlight the most important parts
- Show the flow of data or control
4. Visual Representation (when helpful)
If it helps understanding, create a simple ASCII diagram showing:
- Data flow
- Component relationships
- Process steps
- State changes
5. Key Concepts
Explain any important patterns, principles, or techniques used:
- Why was it done this way?
- What problem does it solve?
- What are the benefits of this approach?
6. Common Gotchas
Point out things that might surprise or confuse people:
- Edge cases
- Common misconceptions
- Things that look like they do X but actually do Y
- Potential pitfalls
Guidelines
- Be conversational: Write like you're explaining to a friend
- Use examples: Concrete examples beat abstract descriptions
- Build understanding gradually: Start simple, add complexity
- Focus on "why": Don't just say what the code does, explain why it matters
- Be encouraging: Make the reader feel like they can understand this
If a file path is provided
- Read the file first
- Understand its context in the codebase
- Explain not just what it does, but how it fits into the bigger picture
