Whereas the previous chapter involved building and publishing OpenAPI specification using a visual editor (Stoplight), in this chapter you code the spec by hand following a step-by-step tutorial using the Swagger Editor. You populate each of the main objects in the OpenAPI spec: openapi, info, servers, paths, components, security, tags, and externalDocs. For each object, you can refer to code samples and see how the source maps to the documentation output. The goal is to gain familiarity with the OpenAPI objects and properties by building a valid OpenAPI file from scratch.

If you’re a beginner or want a visual editor, check out the Getting started tutorial: Using Stoplight Studio to create an OpenAPI specification document instead.
