Midjourney Prompt for Documenting Code
Code documentation is a fundamental pillar of software development, but it often suffers from a painful lack of explanatory visuals. Midjourney opens up a new dimension by enabling the creation of conceptual illustrations, stylized diagrams, and visual representations that make technical documentation accessible and engaging. Instead of being limited to monotonous blocks of text, developers can now generate architecture schemas, visual metaphors to explain design patterns, or infographics illustrating data flow within an application. These visuals do not replace inline code comments, but they significantly enrich wikis, READMEs, onboarding guides, and technical presentations. The key is to craft prompts that are precise enough to produce images that truly serve code comprehension, avoiding overly artistic renderings that would lose their informative value. With the right parameters, Midjourney becomes a formidably effective technical communication tool for development teams.

Why this prompt works
This prompt combines a clean visual style (isometric, flat design, white background) with concrete technical elements (microservices, API endpoints, data flows), grounding the image in a real documentation context. The --style raw parameter and a low --stylize value force Midjourney to remain sober and informative rather than artistic. The 16:9 format is optimized for integration into web pages and technical documents.
Use Cases
Variants
Expected Output
A clean and professional technical illustration showing a software architecture in an isometric view, with distinct colored modules linked by directional arrows. The rendering evokes an official documentation diagram, clear enough to be integrated into a GitHub README, a Confluence wiki, or a technical presentation, while providing a visual dimension superior to classic diagrams.
Frequently Asked Questions
Can Midjourney generate real, usable UML diagrams or flowcharts?
No, Midjourney does not generate technical diagrams in the strict sense with legible text and logically accurate connections. It excels, however, at creating conceptual illustrations and stylized visual representations to accompany documentation. For precise UML diagrams, use dedicated tools like Mermaid or PlantUML, and reserve Midjourney for supporting visuals that make your documentation more engaging and understandable at a glance.
How can I ensure the generated images remain consistent throughout the documentation?
To maintain visual consistency, create a base prompt that you reuse as a template, modifying only the elements specific to each illustration. Set style parameters (--style raw, --stylize, color palette) and aspect ratio (--ar). You can also use the same seed with the --seed parameter to get stylistically similar outputs. Finally, document your prompt template in your contribution guide so the entire team produces harmonious visuals.
Which format and resolution should I choose for embedding images in technical documentation?
For web-based documentation (READMEs, wikis, static sites), the 16:9 format with --ar 16:9 is optimal because it integrates naturally into the reading flow. For presentations, stick with 16:9. For printed documents or PDFs, prefer --ar 3:2 or --ar 4:3. Regarding resolution, use Midjourney's native upscale to get high-definition images, then compress them into WebP or optimized PNG to avoid bloating your documentation. Aim for a final file size between 100 KB and 500 KB per image.

Sora Prompt for Creating E2E Tests
End-to-end (E2E) tests are essential for ensuring application reliability, but writing them remains time-consuming and repetitive. Sora, thanks to its advanced generation capabilities, makes it possible to automate the creation of complete E2E test scenarios in seconds. By formulating a precise prompt describing user journeys, expected interactions, and validation criteria, you obtain structured test suites covering nominal cases as well as edge cases. The prompt engineering approach applied to Sora transforms how QA and development teams approach test coverage. Instead of starting from a blank page, you describe the expected behavior of your application in natural language, and Sora generates the corresponding test code with appropriate assertions. This method significantly reduces the time needed to set up an E2E suite while maintaining a professional quality level. Whether you use Playwright, Cypress, or Selenium, the prompts presented here adapt to your technical stack and the complexity of your application.

GitHub Copilot Prompt for Creating a REST API
GitHub Copilot has become an essential assistant for developers looking to accelerate the creation of REST APIs. Thanks to its direct integration into the code editor, it understands the context of your project and generates structured code in real time. Whether you work with Node.js and Express, Python and FastAPI, or Java and Spring Boot, Copilot adapts to your tech stack to produce endpoints conforming to REST conventions. The main challenge lies in formulating the prompt: a well-structured prompt yields a complete API with data validation, error handling, authentication, and documentation. A vague prompt, on the other hand, will produce generic code requiring many adjustments. In this guide, we offer an optimized prompt that fully leverages GitHub Copilot's capabilities to generate a professional, testable, production-ready REST API. You will also discover variants adapted to your experience level as well as practical tips to get the most out of this tool on a daily basis.
