There’s so much more to your software product than just the code. In order for users to get the most out of your software, you need to provide them with useful documentation – whether that’s for other developers or end users of your product.
In order to provide the best user experience for your software, you need to invest in the right documentation tools to host your documentation. It’s no good just creating a Google Drive folder and expecting that to do the job, as your software is likely to be too complex for such a solution.
Users need straightforward instructions to understand how the software works and what they can use it for. This is where your software documentation comes in.
What Is Software Documentation?
Remember, docs or it didn’t happen. Software documentation is any written document that explains how a piece of software works, why it was built, and how it is intended to be used. Depending on the complexity of your software, your documentation can contain information on the general use of the product and in-depth dives into functions and features.
Software documentation, according to Daniele Procida, can be divided into four categories:
- Learning-oriented tutorials
- Goal-oriented how-to guides
- Understanding-oriented discussions
- Information-oriented reference material
You need all these types of documentation to provide comprehensive instructions for your software product.
