The term software documentation is intimidating to many. Even though it seems self-explanatory (okay, it consists of documents that talk about software), what does that mean exactly?

Sofware documentation refers to all images, video, materials and text instructions that describe how to use computer software. There are two main types of software documentation: user-focused and developer-focused.

Therefore, software documentation is an umbrella term that encompasses a wide variety of different documents, so there's no catch-all definition. However, they're all united by one common goal. They provide information about software. To what end, you might be wondering?

Software documentation provides people with information so that they can effectively use or work on a piece of software. Some documentation helps end-users get oriented, troubleshoot or start using a piece of software. Other documentation provides programmers, developers, software engineers and other industry professionals with more in-depth technical information about a piece of software.

Whatever the case may be, great software documentation should clearly communicate information about a piece of software. People should always finish reading software documentation and take away new knowledge, capabilities or data relating to that piece of software.

As mentioned before, software documentation can be separated into two broad categories: user-focused and developer-focused. Keep reading, because we'll be discussing those documentation types in a little more detail later on.

Who uses software documentation?

The people who use software documentation are as diverse as the kinds of documentation themselves. In fact, there's truly something for everyone when it comes to the different types of documentation. Many people see the words software documentation and automatically assume that they're technical documents that are only used by developers. In reality, this is not always the case.

As we'll discuss in the next section, software documentation can be divided into different categories.

1/ Some kinds of documentation are user-focused, meaning that they're normally read by end-users. This can include anything from customers to testers to external stakeholders.

2/ Other kinds of documentation are developer-focused. These are normally the more technical documents that are assembled and referred back to by developers, programmers, software engineers, project managers and the like.

Of course, these categories are not set in stone. There are also kinds of documentation that are used by end-users and developers alike, as well as more specific sub-categories.

User-focused software documentation

First things first, let's talk about user-focused documentation. By now you've probably figured out that these kinds of documents are intended for customers and other users that are receiving the finished version of your software development products. The goal of this kind of documentation is to help people use your software itself and/or features of your software. It can also provide them with details about your software, teach them how to download it and/or set it up and troubleshoot any issues.


This list is by no means extensive, but some common examples of user-focused software documentation include:

  • How-to and user guides
  • Release notes
  • Tutorials
  • Reference documents
  • Software design documents
  • Explanations (often including videos, graphics & screenshots)
  • Set-up and troubleshooting manuals
  • Frequently asked questions

Developer-focused software documentation

On the other hand, we've got developer-focused software documentation. These documents are normally more technical and are used by people who are a part of developing a software product, or otherwise working on it after the fact. These people include programmers, developers, software engineers, project managers and other stakeholders.

Developer-focused documents are usually more difficult for people without industry experience to understand, but they should still be written as clearly as possible.


A variety of documents can fall under the umbrella of developer-focused software documentation, but here are some common examples:

What to consider when choosing a software documentation tool

There are so many software documentation tools out there for all your documentation needs. However, it can be difficult to determine the best one for your team and specific project. If you ask us, here are some of the top features and considerations to keep in mind when you're thinking about trying some software documentation tools:

  • How's its usability? Is it easy to navigate, or does it require a degree of industry experience to operate?
  • Does it have search functionalities? Is it easy to find the documents you need, or do you need to do some sifting and searching every time?
  • How are its integrations? Will it integrate easily with the web tools you already use, or will you have to move all your data over?
  • Does it include customer service and/or user support? Do they offer demos, live chats, tutorials or user guides? Do they have a FAQ web-page or section?
  • How do its organization features look? Are they advanced? Is it possible to create different channels, categories and sub-categories easily?
  • Are the security features robust? What security norms, laws and qualifications are they compliant with? Do they offer different levels of security and/or accessibility?
  • What elements can be added into your documentation? Is it easy to integrate things like source code snippets, files, videos, photos and embeds?
  • Does its cost fit into your budget? Will you take advantage of its full array of features and functionalities?

If you consider the above questions and answer them honestly, you'll be able to easily identify the best software documentation tools for you and your team.

What's the best software to use for software documentation?

What's so great about software documentation?

There are so many reasons why excellent software documentation is absolutely key in the software development process. We could write an entire article about that in itself. Nevertheless, the most important reason is that it helps people use your software product. This might sounds obvious, but if you dive into it a little more, you'll see what we mean.

You can have an incredible product roadmap and develop the most amazing piece of software in the world, but if no one can use it, it isn't worth much. Equally, if no one understands the technical details behind your software, it'll be impossible to update it or improve it in the future. Excellent software documentation ensures that internal and external parties alike will understand and be able to use your software and the full range of its features. This is incredibly powerful and is not a given without clear documentation.

There are tons of associated benefits that come along with people having a great understanding of how to use your software. You'll save time, increase efficiency, improve internal and external relationships, foster clear communication, stay organized, establish sustainable workflows & professional systems, increase credibility, contribute to your branding and encourage effective collaboration... just to name a few.

Our top tips for writing great software documentation

The term software documentation is intimidating. Unfortunately, it's become associated with highly technical documentation that's long, confusing and jargon-heavy. This doesn't have to be the case. In fact, if you can produce clear, helpful software documentation, you'll truly fulfill the goal behind software documentation: helping people use your software.

These tips will help make sure that your documentation development process goes off without a hitch:

1. Hire a professional

If there's someone on your team who's a great writer, fantastic. If they're willing, there's no problem with putting them in charge of writing your software documentation. However, if you don't have any obvious choices for writers on your team, consider hiring a professional tech writer.

Many people make the mistake of assigning software documentation to any random person on their team, regardless of their writing or technical skills. This is one of the big driving forces behind confusing or poorly assembled documentation. Technical writers in the software field have both industry know-how and writing experience. They'll also be complicated dedicated to the writing process. Hiring one is well worth your while.

2. Make a Documentation Plan

Another common mistake in software documentation is diving in before you're done planning. Insist on making an outline of all the different kinds of documentation you and your team will be working on. This will help you stay organized throughout the development process and make it much easier to delegate work to different teams.

Documentation plans also help ensure a higher degree of writing quality. You'll avoid repeating information and it'll be easier for your readers to navigate between your documents overall.

3. Don't forget version control

Software documentation is dynamic. By the end of your software product's lifecycle, it's likely that you'll go through at least a few versions of your documentation. In order to make sure your documentation stays effective and valuable, you'll need to have a system in place that helps with version control and always displays the most up to date information.

Nowadays, many teams use design documentation templates that saves automatically and updates in real-time

4. Work collaboratively

Software and product documentation is always best written collaboratively. Harness the strengths of different team members and assign them documentation that will make their best abilities shine.

Working on documentation collaboratively also saves time and helps you get things done much faster. Writing documentation is labour intensive and it doesn't make sense to have one or two people spending months on something that could take weeks when worked on as a team.

5. Think about your audience

There's a wide variety of software documentation types out there. When getting started, it can be difficult to determine what kind of content you need to produce and what can be left out. The easiest way to prioritize what kind of documentation you need to put together is by thinking about your audience. Determining whether you're writing for end-users or programmers and engineers right off the bat will help you narrow down the kind of documentation you want to focus on.

6. Put together a style guide

When it comes to documentation of any kind, consistency and design are important. Make sure all your documentation looks like it belongs together. This will make it more appealing to read and easier to navigate. A good way to ensure that your documentation stays consistent when it's being assembled by a team is putting together a style guide. Style guides can encompass everything from language & writing style to formatting and fonts.

Find out what software documentation can do for you

As you can see, having killer software documentation is an incredible asset for both your development team and your software product itself. You'll empower your users to truly enjoy getting to know your software and putting it into action. You'll avoid frustrations and build trust by providing users with resources and answering their questions before they have to ask. You'll provide developers and other internal team members with the key information they need to do their best work and produce amazing results, right now and in the future.

The documentation development process might feel overwhelming at the outset, but keep this guide to refer back to and you'll be writing away in no time. Put together your documentation plan, take things step-by-step and you'll be amazed at what you come up with.

Be sure to think about our considerations when choosing a software or web tool to help with your documentation development process, take a browse through the options we've curated to help make writing and working on your documentation easy and enjoyable and refer back to our tips and tricks when it comes to writing your software documentation.

The sky's the limit, so dive into the world of software documentation and hit the ground running.
