- Avoid vague explanations
- Customize for your project
AI-generated documentation should be reviewed carefully.
Strong Documentation Prompt Example
Act as a senior software architect. Create structured documentation for a REST API that handles user authentication, including request format, response structure, and possible error codes.
Structured prompts give better documentation.
Benefits of Using ChatGPT for Documentation
- Saves time
- Improves clarity
- Standardizes structure
- Helps non-technical users
- Speeds up onboarding
But always review before sharing publicly.
Summary
ChatGPT can assist developers in writing project documentation, API docs, README files, installation guides, and user manuals. It helps structure and refine technical content efficiently.
However, developers must validate all technical details before publishing documentation.
