How to start technical writing as a side hustle: step-by-step for beginners

By FastBuySale Newsroom · 9 Nov 2026 · 17m ago

What technical writing involves

Technical writing turns complex information into clear, usable documentation. Unlike marketing content, its goal is to help readers complete tasks or understand systems accurately. Typical deliverables include installation guides, user manuals, knowledge base articles, onboarding tutorials, API documentation, standard operating procedures, release notes and troubleshooting guides. Good documentation reduces support requests and helps customers succeed with products.

Types of documentation

End-user documentation helps customers use products. Developer documentation explains APIs, software development kits and integrations. Internal documentation covers procedures, policies and training for staff. Each type has different audiences, depth and style.

Core skills

Clear, concise writing is the foundation. Equally important are research, asking good questions, organising information logically, understanding audiences and paying attention to accuracy and consistency.

Learning the tools

Many teams write in markdown and store documentation in version control, publishing through documentation site generators. Others use help authoring tools or knowledge base platforms. Learn the basics of markdown, version control and at least one documentation platform.

Choosing a niche

Software, cloud services, developer tools, finance technology, healthcare technology, manufacturing and engineering are common niches. A background in one of these fields is a strong advantage.

Worked example: side income

Priya writes four help articles per month for a software company at 120 dollars each, earning 480 dollars. Each takes about 3 hours, so she earns 40 dollars per hour. She also completes one installation guide per month for 400 dollars in 8 hours, or 50 dollars per hour. Her total is 880 dollars for 20 hours, an average of 44 dollars per hour. The percentage calculator on this site helps compare project types.

Step one: study good documentation

Read documentation from well-regarded software companies and open source projects. Notice how they structure getting started guides, use headings and numbered steps, include examples and screenshots, and write short sentences. Compare documentation that helped you with documentation that confused you, and note the differences. Free style guides published by large technology companies explain conventions for voice, terminology, formatting and accessibility, and are excellent learning resources.

Step two: create writing samples

Build three to five samples that show range. Document an open source tool's installation, write a troubleshooting guide for a common software problem, create an API reference for a public API or rewrite a confusing set of instructions. Publish samples on a simple portfolio site or code hosting profile. Explain the audience and purpose for each.

Step three: contribute to open source

Many open source projects welcome documentation improvements. Contributing gives you real published work, feedback from maintainers and experience with version control workflows.

Step four: find first clients

Look for startups and small software companies with thin documentation, check job boards for contract documentation roles and contact agencies that provide content to technology clients. Mention specific improvements you could make to a company's help centre. Your current employer may also need documentation, which can provide experience.

Step five: set your prices

Technical writing is often priced per hour, per article or per project. Estimate research time, interviews, writing, screenshots and reviews. Complex technical topics deserve higher rates. Avoid pricing purely per word, since research often takes longer than writing.

Working with subject matter experts

Engineers and product specialists often hold the knowledge you need. Prepare focused questions, record interviews with permission, respect their time and send drafts for technical review. Building good relationships with experts makes projects faster.

Following style guides

Clients usually have style guides covering terminology, tone and formatting. Follow them carefully. If none exists, propose a simple one.

Reviews and versions

Documentation goes through technical and editorial reviews. Agree on review rounds and deadlines in advance. Products change, so documentation needs updates when features change; offer maintenance work.

Common beginner mistakes

Mistakes include writing for experts when readers are beginners, skipping testing of instructions, ignoring style guides, underpricing research time, failing to agree review rounds and presenting samples without context.

Managing time around a job

Batch research and writing sessions, set realistic deadlines and avoid conflicts of interest with your employer.

Growing your side hustle

Specialising in developer documentation or regulated industries can lead to higher rates and steady contract work.

Testing your instructions

Every procedure you write should be tested by following it exactly as written, ideally on a fresh setup. Testing reveals missing steps, unclear wording, outdated screenshots and assumptions about prior knowledge. Ask a friend unfamiliar with the product to follow your guide and note where they hesitate. Documentation that works first time builds enormous trust with clients and readers, and testing is one of the clearest differences between careful documentation professionals and writers who simply rewrite existing text.

Writing for your audience

Before drafting, identify who will read the documentation, what they already know and what they need to accomplish. A beginner installing an app needs plain language and screenshots, while a developer integrating an API needs precise parameters, code samples and error codes. Writing at the wrong level frustrates readers. Personas or short audience descriptions help keep content focused.

Structuring information

Use clear headings, short paragraphs, numbered steps for procedures and bullet lists for options. Put the most important information first. Separate concepts, tasks and reference material so readers can find what they need quickly. Consistent structure across articles makes help centres easier to navigate.

Using visuals well

Screenshots, diagrams and short videos can clarify complex steps. Keep visuals current, crop to relevant areas, add callouts sparingly and include alternative text for accessibility. Avoid relying only on images to explain critical steps.

Learning technical basics

You do not need to be an engineer, but understanding basics such as how web applications work, what APIs do, command line usage and simple code examples makes you far more effective with software clients.

Writing API documentation

API documentation is one of the best paid areas of technical writing. It usually includes an overview, authentication instructions, endpoint references with parameters and responses, error codes, rate limits and practical code examples in common languages. Practise by documenting a free public API, testing each request with a simple tool and explaining results clearly. Learning to read code samples and basic data formats such as JSON makes this work far easier and opens doors to developer tools companies.

Writing release notes

Release notes tell users what changed in a product update. Good notes group changes into new features, improvements and fixes, explain benefits in plain language and link to detailed guides. Many software companies need help writing them consistently every release, which can become regular side work.

Building a knowledge base

Some clients need an entire help centre created from scratch. Plan categories around user goals, write the most common tasks first and use consistent article templates. Review support tickets to find the questions customers ask most often, since these reveal the content gaps that matter.

Accessibility and inclusive language

Write in plain language, use descriptive link text, add alt text to images and avoid idioms that confuse international readers.

Writing procedures for businesses

Not all technical writing involves software. Manufacturers, clinics, warehouses, restaurants and offices need standard operating procedures, safety instructions, training manuals and equipment guides. These clients value writers who can observe a process, ask staff detailed questions and turn their knowledge into clear step-by-step documents. Local businesses are often easier to approach than large software firms, and procedure writing can be a strong entry point for side hustlers with experience in a particular industry.

Using contracts and scopes

Agree in writing what documents you will produce, the expected length, the number of review rounds, deadlines, access to experts and payment terms. Clear scopes protect your time when products change mid-project.

Joining documentation communities

Online communities for documentation professionals share job leads, tool advice, templates and feedback on samples. Many also host free events and mentoring programs that help beginners grow faster.

Keeping records

Track projects, hours, invoices and software costs. Side income is usually taxable, so keep tidy records throughout the year.
