 The playground is automatically generated from your OpenAPI specification or AsyncAPI schema so any updates to your API are automatically reflected in the playground. You can also manually create API reference pages after defining a base URL and authentication method in your `docs.json`.
 
 We recommend generating your API playground from an OpenAPI specification. See [OpenAPI Setup](/api-playground/openapi-setup) for more information on creating your OpenAPI document.

 The `x-mint` extension is recommended so that all of your API documentation is automatically generated from your OpenAPI specification and maintained in one file.
 
 Individual `MDX` pages are recommended for small APIs or when you want to experiment with changes on a per-page basis.
 
 For more information, see [x-mint extension](/api-playground/openapi-setup#x-mint-extension) and [MDX Setup](/api-playground/mdx/configuration).
