+# `swagger-ui-react`
+
+[![NPM version](https://badge.fury.io/js/swagger-ui-react.svg)](http://badge.fury.io/js/swagger-ui-react)
+
+`swagger-ui-react` is a flavor of Swagger UI suitable for use in React applications.
+
+It has a few differences from the main version of Swagger UI:
+* Declares `react` and `react-dom` as peerDependencies instead of production dependencies
+* Exports a component instead of a constructor function
+
+Versions of this module mirror the version of Swagger UI included in the distribution.
+
+## Quick start
+
+Install `swagger-ui-react`:
+
+```
+$ npm i --save swagger-ui-react
+```
+
+Use it in your React application:
+
+```js
+import SwaggerUI from "swagger-ui-react"
+import "swagger-ui-react/swagger-ui.css"
+
+export default App = () => <SwaggerUI url="https://petstore.swagger.io/v2/swagger.json" />
+```
+
+## Props
+
+These props map to [Swagger UI configuration options](https://github.com/swagger-api/swagger-ui/blob/master/docs/usage/configuration.md) of the same name.
+
+#### `spec`: PropTypes.object
+
+An OpenAPI document respresented as a JavaScript object, JSON string, or YAML string for Swagger UI to display.
+
+⚠️ Don't use this in conjunction with `url` - unpredictable behavior may occur.
+
+#### `url`: PropTypes.string
+
+Remote URL to an OpenAPI document that Swagger UI will fetch, parse, and display.
+
+⚠️ Don't use this in conjunction with `spec` - unpredictable behavior may occur.
+
+#### `onComplete`: PropTypes.func
+
+A callback function that is triggered when Swagger-UI finishes rendering an OpenAPI document.
+
+#### `requestInterceptor`: PropTypes.func
+
+> `req => req` or `req => Promise<req>`.
+
+A function that accepts a request object, and returns either a request object
+or a Promise that resolves to a request object.
+
+#### `responseInterceptor`: PropTypes.func
+
+> `res => res` or `res => Promise<res>`.
+
+A function that accepts a response object, and returns either a response object
+or a Promise that resolves to a response object.
+
+## Limitations
+
+* Not all configuration bindings are available.
+* OAuth redirection handling is not supported.
+* Topbar/Standalone mode is not supported.
+* Custom plugins are not supported.
+
+We intend to address these limitations based on user demand, so please open an issue or pull request if you have a specific request.
+
+## Notes
+
+* The `package.json` in the same folder as this README is _not_ the manifest that should be used for releases - another manifest is generated at build-time and can be found in `./dist/`.
+
+---
+
+For anything else, check the [Swagger-UI](https://github.com/swagger-api/swagger-ui) repository.
