## About Redoc
Redoc is an open source tool for generating documentation from OpenAPI (formerly Swagger) definitions.
By default Redoc offers a three-panel, responsive layout:
- The left panel contains a search bar and navigation menu.
- The central panel contains the documentation.
- The right panel contains request and response examples.

## Live demo
If you want to see how Redoc renders your OpenAPI definition,
you can try it out online at https://redocly.github.io/redoc/.
A version of the Swagger Petstore API is displayed by default.
To test it with your own OpenAPI definition,
