<aside> ℹ️ API documentation is a set of instructions provided to API users to aid in the integration process. It is a short guide that has all the information needed to use the API, which explains functions, classes, return types, arguments, and more. Some documents may also provide examples on how their system work and how to implement more changes.

API description formats like the OpenAPI/Swagger Specification have automated the documentation process, making it easier for teams to generate and maintain them.
