 [![NPM version](https://badge.fury.io/js/swagger-ui.svg)](http://badge.fury.io/js/swagger-ui)
 
-## New!
-
-**This is the new version of swagger-ui, 3.x. Want to learn more? Check out our [FAQ](http://swagger.io/new-ui-faq/).**
-
 **👉🏼 Want to score an easy open-source contribution?** Check out our [Good first issue](https://github.com/swagger-api/swagger-ui/issues?q=is%3Aissue+is%3Aopen+label%3A%22Good+first+issue%22) label.
 
-As a brand new version, written from the ground up, there are some known issues and unimplemented features. Check out the [Known Issues](#known-issues) section for more details.
+**🕰️ Looking for the older version of Swagger UI?** Refer to the [*2.x* branch](https://github.com/swagger-api/swagger-ui/tree/2.x).
+
 
 This repository publishes to two different NPM modules:
 
-* [swagger-ui](https://www.npmjs.com/package/swagger-ui) is a traditional npm module intended for use in JavaScript web application projects that are capable of resolving dependencies (via Webpack, Browserify, etc).
-* [swagger-ui-dist](https://www.npmjs.com/package/swagger-ui-dist) is a dependency-free module that includes everything you need to serve Swagger-UI in a server-side project, or a web project that can't resolve npm module dependencies.
+* [swagger-ui](https://www.npmjs.com/package/swagger-ui) is a traditional npm module intended for use in single-page applications that are capable of resolving dependencies (via Webpack, Browserify, etc).

+
+We strongly suggest that you use `swagger-ui` instead of `swagger-ui-dist` if you're building a single-page application, since `swagger-ui-dist` is significantly larger.
 
-For the older version of swagger-ui, refer to the [*2.x branch*](https://github.com/swagger-api/swagger-ui/tree/2.x).
 
 ## Compatibility
-The OpenAPI Specification has undergone 5 revisions since initial creation in 2010.  Compatibility between swagger-ui and the OpenAPI Specification is as follows:
