 **This is the README for the `2.x` version of Redoc (React-based).** 
 **The README for the `1.x` version is on the [v1.x](https://github.com/Redocly/redoc/tree/v1.x) branch**
 
+## About Redoc
+
+Redoc is an open-source tool for generating OpenAPI(aka 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, and the right panel contains request and response
+examples. 
+

+## Live demo
+
+If you want to see how ReDoc will render 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,
+enter the URL for your definition and select **TRY IT**.
+
+## Redoc vs. Redocly Reference docs
+
+Redoc Community Edition is free open-source software (OSS).
+Redocly has developed extensive enhancements on top of Redoc Community Edition's open core, creating Redocly Reference Docs.
+See [Comparison Redoc CE vs. Redocly Reference Docs](https://redoc.ly/redoc-vs-reference/)
+for the main differences between the Redoc Community Edition and Redocly Reference Docs.

 ## Deployment
+
+### TL;DR final code example
+
+To render your OpenAPI definition using Redoc, use the following HTML code sample and
+replace the `spec-url` attribute with the url or local file address to your definition.
+
+```html
+<!DOCTYPE html>
+<html>
+  <head>
+    <title>Redoc</title>
+    <!-- needed for adaptive design -->
+    <meta charset="utf-8"/>
+    <meta name="viewport" content="width=device-width, initial-scale=1">
+    <link href="https://fonts.googleapis.com/css?family=Montserrat:300,400,700|Roboto:300,400,700" rel="stylesheet">
+
+    <!--
+    Redoc doesn't change outer page styles
+    -->
+    <style>
+      body {
+        margin: 0;
+        padding: 0;
+      }
+    </style>
+  </head>
+  <body>
+    <redoc spec-url='http://petstore.swagger.io/v2/swagger.json'></redoc>
