OpenAPI definitions are simple JSON or YAML files that you can create and edit with any text editor. But the right tooling can make your job a lot easier. In this article, we would like to showcase one of tools for the API design stage, the Swagger Editor, and be your step-by-step guide for creating your first OpenAPI definition.
Swagger Editor is freely available online at editor.swagger.io.
