Beyond the Code: Documenting Software Products for Growth

Great software deserves great documentation. It's more than just a manual; it's a critical bridge between your product and its users, a powerful tool for user adoption, support reduction, and ultimately, business growth. High-quality documentation empowers users, fosters confidence, and turns casual visitors into loyal advocates.

But how do you create documentation that truly stands out? Let's explore best practices for building documentation from scratch, then dive into leading tools and advanced strategies.

Building Docs from Scratch: A User-First Approach

Regardless of the tool you choose, the content strategy is paramount. Here's how to approach building high-quality documentation:

1. Hook Them Early: The Introduction Page

Your introduction page must be short, simple, and direct. Immediately answer:

  • Why does this product matter to me, and
  • What problem does it solve?

Avoid jargon. If it's not instantly compelling, users move on.

2. Improve on Competitor Documentation

If your product offers features similar to competitors, you don’t need to start documentation from scratch. Studying competitor docs can save time and highlight proven patterns that already work for users.

When reviewing competitor documentation, consider:

  • Structure & flow: How they organize onboarding, feature explanations, and advanced topics.

  • Clarity & examples: What kind of examples, diagrams, or walkthroughs help users understand faster.

  • Common pain points: Which areas are over-explained or under-explained, and where users might still struggle.

Use this research as inspiration—not duplication—to write clearer, more developer-friendly documentation that improves on what already exists.

3. The Power of Visuals: Mermaid Diagrams

Developers prefer visual understanding. Use workflow diagrams and images. Mermaid allows text-based diagrams (flowcharts, sequence diagrams) rendered directly, making complex processes instantly clear. You typically install it via npm and integrate it into your documentation site. Images speak more than words.

Learn more about setting up and using Mermaid for your documentation from their official documentation.

4. Supercharging Docs with AI Integration

AI transforms user interaction with documentation:

  • "Copy to LLM" Feature: One-click copy for pages or sections. Users can paste into LLMs (Gemini, ChatGPT) for personalized questions, code generation, or troubleshooting. Unparalleled self-service.
  • AI-Powered Help Bots: Integrate a chatbot trained on your docs for instant answers, guided tours, or relevant section links, offering "extra help assistance."

5. Styling Guides

For features, especially those similar to competitors, draw inspiration from leaders like Stripe or Google Cloud. Focus on:

  • Clarity: Concise language, following style guides from Google Developers or Microsoft Learn.
  • Use Cases: Explain when and why a user needs a feature, not just how.
  • Developer Examples: For dev tools, show exact API calls, configuration files, or command-line inputs. For example, documenting an API client like Bruno needs real-world .bru file examples.

6. Build a Strong Feedback Loop With Your Community

Documentation improves fastest when it’s shaped by real user feedback. Whether your product is commercial or open source, maintaining a regular feedback loop is essential.

A simple and effective approach:

  • Connect with the community monthly (Discord, Slack, GitHub, or community calls).

  • Ask specific questions like:

    • “What part of the docs was confusing?”

    • “What did you have to figure out on your own?”

  • Track recurring feedback and update docs incrementally.

Treat documentation as a living product. Regular feedback helps ensure your docs stay accurate, relevant, and aligned with how users actually use your software.
