 There are two versions of OpenFL, the first is primarily distributed using haxelib, and blends native support for Windows, macOS, Linux, iOS, Android, Flash, HTML5 and WebAssembly. You can read more about the haxelib distributed version of OpenFL, [here](https://github.com/openfl/openfl).
 
-The second edition of OpenFL is distributed using NPM, and is designed for use from TypeScript, JavaScript (EcmaScript 5 or 6+) or Haxe, the latter of which can be used in both versions of OpenFL. The NPM version of OpenFL is designed to be used in a browser environment. The NPM version also has (beta) support for ActionScript 3.0.

 ## Running the Project
 
 You can start a development server by going to the root directory of your project, and running `npm start`. In addition to compiling your application, it will open a new window in your web browser, with hot reloading enabled. This means that if you edit the `app.ts`, `app.js` or `App.hx` source file, the server will automatically compile your changes, and reload the current window, speeding up development. Now we can making more changes.
