Technical Documentation for Small Teams

Sebastian Schürmanns

Some years ago, when I started a new job at a small software company, there was nearly no technical documentation at all. All important information was spread across multiple places: a ticket system with integrated and rarely used wikis, and a giant Google Drive with hundreds of documents. The content was mostly unstructured – user guides, technical concepts, internal notes, and business documents all mixed together.

Looking around Reddit and other forums, it’s clear that this is not an unusual situation. Many startups and small companies struggle with the same problem: documentation exists. But it’s scattered, messy, outdated, or hard to find. Let’s take a look at why this is a problem – and more importantly – how small teams can fix it without enterprise tools or heavy processes.

The Problem of Missing Documentation

Small companies and startups often grow around their founders and early teams. These people have a lot of knowledge – but most of it lives in their heads.

In the early days, that works fine. But as the company grows, people leave, and new teams join, missing documentation quickly becomes a real problem. Critical knowledge is hidden in old tickets, scattered Google Docs, or forgotten Slack threads. And suddenly, simple questions turn into time-consuming research. And in the worst case, complex product decisions are avoided simply because nobody remembers the background.

This is where missing documentation becomes dangerous: small companies lose their agility. And without agility, they lose their competitive edge. This problem is often explained by the typical mindset of small companies: focus on execution, not documentation. But let’s face it – at some point, documentation is execution.

When Technical Documentation Makes a Difference

If you’ve ever worked on documentation for large software systems or complex business processes – whether using pure text, UML diagrams, or even tools like Enterprise Architect – you know the effort pays off later. When done right, technical documentation becomes the foundation of your product development. It helps teams align, uncover hidden problems, and make better decisions. And this can provide a real competitive advantage in the long run: you can build better solutions, faster.

The good news? You don’t need enterprise-level tools for that. No need for Enterprise Architect or expensive documentation platforms. There are plenty of lightweight tools to get started – and we’ll look at some of them later.

How to Introduce Documentation in Small Teams

Introducing technical documentation into small companies is similar to adopting an agile framework: It requires breaking old habits and routines. And that only works if it’s initiated and backed by company leaders.

As with any process, it helps to establish clear rules, processes, and responsibilities when introducing technical documentation. Here’s a simple approach:

  • Kickoff meeting: Assign the right priority to documentation.
  • Establish rhythm: Set rules, such as documenting every new feature before a release.
  • Clarify responsibilities: Define who is responsible, e.g., developers and product managers.
  • Appoint a documentation owner: Assign someone to manage the process and oversee the documentation.

So far, so top-down. But if you want the process to thrive and become a living document, there are also bottom-up approaches:

  • Make it easy and enjoyable: Nobody likes writing docs, so make the process as smooth and painless as possible.
  • Use tools your team likes: Let your team choose the tools they enjoy working with.
  • Create rewards and incentives: Motivate your team to contribute to documentation.

For the last point, why not leverage your favorite AI service for ideas? Just use a prompt like, "What kind of measures can you think of (e.g., benefits) to motivate your team to write documentation?" You'll get tons of good suggestions – just grab what fits your business and team.

How to Get Started

If you're responsible for the documentation process, it can feel overwhelming, and finding a starting point may be challenging.

If you already have scattered documentation in your company, the best place to start is by gathering all the pieces in one central location. From there, you can organize, sort, and improve it incrementally. If you don’t have any existing documentation, the approach depends on your preferences. You can start by mind-mapping and setting up a structure, and then fill in the details as you go. If that doesn't suit your team, it can be helpful to simply begin the documentation process and establish a routine. You can always structure and refine the information as you move forward, adding older content later as needed. This way, your documentation will grow naturally.

To get a sense of how to structure your documents, you can use templates (the good docs project is a great starting point), or adopt a system like Diátaxis, developed by Daniele Procida with Divio and widely adopted in the software industry. While these resources are more suited to public software documentation, you’ll find similar systems and resources for other areas as well.

Simple Software for Technical Documentation

When it comes to documentation software for small companies and startups, there’s really only one rule: a simple setup and a good user experience are more important than features. The biggest challenge you’ll face is that nobody really likes writing technical documentation – so your software should make the process as easy and enjoyable as possible.

Here are some options that work well for small companies.

Typemill

Typemill is self-hosted flat file CMS designed for documentation, knowledge bases, and other informational websites. It doesn’t offer enterprise-level features like real-time collaboration or complex integrations. But it provides a super simple way to write in Markdown syntax and to structure your documentation hierarchically with drag & drop. Its clean author interface is especially helpful if non-technical users are involved in the documentation process.

Typemill is open source but also offers premium themes and plugins for a low annual fee. There are some more advanced plugins available, like an ebook plugin that can generate PDF and EPUB files from your content – though these are often not essential for basic documentation needs. Typemill runs on PHP with Apache or Nginx and doesn’t require a database, so it can usually be hosted on inexpensive standard web hosting packages.

BookStack

While Typemill is more of a traditional content management system, BookStack is closer to a wiki. It organizes content into "books," "chapters," and "pages," and its interface is simple and user-friendly, making it a good option for teams without technical expertise.

BookStack is somewhat similar to Typemill. It may require a bit more setup, but it's still manageable. The best recommendation is to install both and decide together with your team which one suits your workflow better.

Docusaurus

If your team is entirely technical, you can also use static site generators like Docusarus to create your documentation. This approach is very common in developer teams, but keep in mind that these tools don’t provide a user interface out of the box. You’ll either work directly with Markdown files or need to combine several tools into a deployment pipeline.

I picked Docusaurus here because it’s one of the most popular tools for documentation. But there are many other static site generators that can do a similar job.
