What is Software Documentation?

Once you are done with software development, you already know how each element works and have already memorized or made notes of key functions and capabilities, thus finding the process of documentation unnecessary. However, without documentation, your software is like a black box. 

A black box, in terms of software, can be defined as an object or a system whose inner workings, designs or implementations are hidden from the outside world. The system works like its intended to, however, it can’t be customized to your wants and needs.

Benefits of API Documentation Software

Having a set of descriptor documents for your API allows people to 

  • Reduced Need for Support: A well-written and simple set of API documents helps users find their way around the API and not rely on API development support for external customers and internal use.
  • Higher Adoption Rate: Documenting helps improve the user experience throughout the API lifecycle and allows users to start working with your API much sooner.
  • Extensive Programmability: API documentation uses many programming languages such as PHP, JSON, Java (JavaScript), RAML, and YAML.
  • Non-Engineering Usability: Most documentation software produces reference documentation and other material that people with no software engineering experience can easily understand. 
  • Better Product Maintenance: Documentation provides developers a bird’s eye view of the entire API structure. This allows for better maintenance and updates and quicker improvement cycles. 
  • API Specs Agreement: Creating complete documents for API allows developers and stakeholders to agree on specifications such as the data, attributes, endpoints, and more.


Software documentation is essential for a successful project. When programmers do their work well, the documentation will be automatically generated, and when there are bugs in the product or it’s missing some features, the documentation will be updated by itself, without even involving any other team members.

These days, every organization wants to run a successful project. However, more than 50% of these projects fail because of poor documentation and administration processes. This failure is not intentional but due to lack of knowledge about the tools used for documentation.
