The Different Types of Technical Documentation - Part 2

Have you ever tried building a bookshelf with instructions that looked like ancient hieroglyphs? Technical documentation is the hero (or sometimes villain) in those moments, depending on how well it’s written. But not all technical docs are created equal!

Let’s unzip the folder and take a good look.

Why Do We Have So Many Types?

Think of technical documentation as a Swiss Army knife: different tools for different jobs, all aimed at making complex stuff clear. Some docs teach, some guide, some reference, and some persuade. Whether you’re onboarding new hires, supporting customers, or wooing investors, there’s a flavor of documentation made just for the job.

Main Categories of Technical Documentation

1. Product Documentation

This is the bread-and-butter of technical writing explanations and guides to help users (and sometimes developers) use, maintain, or troubleshoot a product.

Examples

• User Guides & Manuals: How to install, use, or fix your new gadget, from coffee machines to apps.

• API Documentation: For developers, explaining how to connect and use an API (imagine Ikea instructions, but for software).

• Release Notes: Tells users what’s new, what’s fixed, and sometimes, what’s mysteriously changed.

• Installation & Setup Guides: Exactly what you need so your software doesn’t break your computer (or your spirit).

2. Process Documentation

Designed for teams working behind the scenes, these docs standardize workflows, clarify procedures, and keep chaos out of the office kitchen.

Examples

• Standard Operating Procedures (SOPs): How to handle tasks consistently (like “how to never accidentally mass-email the company, again”).

• Internal Wikis: Living documents for employees about policies, IT support, and “don’t microwave fish in the break room” rules.

• Project Plans & Roadmaps: Step-by-step blueprints for launching products or features.

3. Sales and Marketing Documentation

Not all tech docs live in a server room are crafted to close deals, attract partners, and explain stuff to the outside world.

Examples

• White Papers & Case Studies: Deep dives or real-world success stories that show your product rocks (with numbers to prove it).

• Proposals & RFPs (Requests for Proposal): Persuasive docs outlining why your team deserves the big contract or funding.

Other Common Types

Type	Purpose/Use	Example
Tutorials	Teach new users, step-by-step	“How to Set Up Two-Factor Authentication”
Reference Docs	Deep technical details for experts	System architecture diagrams, data sheets
Troubleshooting Guides	Solve common problems	“Why won’t my printer print?!” checklist
System Admin Manuals	Guide IT pros in setup, maintenance	Database backup procedures
Business Requirements Docs	Define what needs to be built and why	“Mobile App Must Support Dark Mode”
FAQs & Knowledge Bases	Answer recurring questions	“Can I reset my password from my phone?”

The “Diátaxis” Model: 4 Pillars of Great Documentation

Inspired by the Diátaxis Framework, top-notch documentation typically falls into four buckets:

• Tutorials: Structured learning for newbies (“how do I get started?”)

• How-To Guides: Solutions for specific problems (“how do I…?”)

• Technical Reference: Everything detailed but dry (“what do all these features do?”)

• Explanations: Deep dives to build understanding (“why does it work this way?”)

Getting these types straight keeps readers and your support team happy.

Pro Tips

Brilliant docs are like good jokes: clear, concise, and everyone gets the punchline. When writing or reading technical documentation, always:

• Spell out acronyms (unless you’re in a secret spy agency).

• Add diagrams or screenshots for visual learners (we all love pictures!).

• Update often-outdated docs are the technical version of “See page 394”... except there’s no page 394.

Technical documentation isn’t just about checklists and user manuals. It's the unsung hero that transforms digital chaos into user delight. Next time you enjoy a seamless app setup or fix a printer with a single tip, thank the docs and the technical writers who (hopefully) made them funny, too.
