Technical Documentation: Types, Benefits, Best Practices & Examples

Technical Documentation

Technical documentation serves as the backbone of user support and product understanding in the technology sector. It guides users through the complexities of products and services and provides a reference point for developers and stakeholders.

GitHub’s survey reveals that incomplete or outdated documentation is a pervasive problem, observed by 93% of respondents, yet 60% of contributors say they rarely or never contribute to documentation.In this blog, we will discuss the purpose of technical documentation, its types, and its benefits. We will also explore the best practices for creating it, some examples, and explore software for the same.

What Is Technical Documentation?

Technical documentation is the process of creating documents that explains the use, functionality, creation, or architecture of a product or service. 

It’s normally targeted toward users, system administrators, and support staff, but it can also target developers, project managers, or anyone else involved in developing, maintaining, or using an application or system. 

It is crucial to ensure that hardware or software products can be used as intended, helping to reduce support costs, improve user experience, and ensure compliance with industry standards or regulations.

A common example of technical documentation is the API documentation provided by software services like GitHub or Google Maps. These documents detail how developers can utilize the API to integrate the service’s functionality into their own applications.

Best Practices for Writing Technical Documentation

Writing insightful technical documentation helps users, developers, and stakeholders understand and utilize technology products and systems efficiently. Here are some best practices for writing technical documentation:

Preliminary Research

Start by defining the purpose of your documentation. What problem does it solve? Create an outline or mind map to organize your content. 

Understand who your readers are. Are they developers, system administrators, or end-users? Tailor your content accordingly. Write user stories to capture different scenarios as it helps you address specific use cases.

Know Your Audience

Create user personas to represent different types of readers. Understand their goals, knowledge level, and pain points.

Map out how users will navigate through your documentation. Consider their entry points and the paths they might take.

Use a consistent tone — formal or friendly, based on your audience. Avoid jargon unless it’s industry-standard.

Navigational Structure & Design

A well-organized TOC is essential. You can organize it by grouping related topics under clear headings. Use hierarchical headings (H1, H2, etc.) to create a logical flow. H1 represents the main topic, followed by subtopics.

Link related sections within your documentation. For example, link from a concept explanation to a detailed procedure.

Template Creation

Technical documentation templates ensure uniformity – create templates for different document types (e.g., installation guides, API references). You can use dedicated technical documentation software with pre-approved knowledge base templates.

Create reusable snippets (e.g., code examples, troubleshooting steps) to insert across documents. If your documentation is version-specific, clearly indicate which version it applies to.

Reader-Friendly Content by Using Multimedia

Break down information into smaller chunks using short paragraphs, bullet points, and numbered lists. Include relevant images, diagrams, screenshots, and videos. Visuals enhance understanding and break up the text.

Incorporate real-world examples and use cases. Show how to apply concepts in practice. Format code consistently. Use syntax highlighting and annotating essential parts. Use callout boxes (e.g., tips, warnings, notes) to highlight critical information.

Choose the Right Software

Look for technical documentation software that is easy to use, lightweight, and widely supported. It should be ideal for version-controlled documentation and enable internal collaboration with internal comments. 

Robust knowledge base tools enable advanced analytics to give you a bird’s eye view of the performance of your technical documentation – total searches, failed searches, articles created, total reads, popular and poorly rated articles, failed keywords, new articles created, and more.

Consistent Auditing & Updating

Regularly review your documentation. Correct inaccuracies, update screenshots and verify links. Clearly label versions (e.g., v1.0, v2.1). Archive outdated versions. 

Encourage users to provide feedback. Use analytics to track popular pages and identify pain points.
