+## Development Server
-For an extended setup example, check out the /playground directory, which includes a fully running VM instance.
+This requires Node.js to be installed.
-```js
-var VirtualMachine = require('scratch-vm');
-var vm = new VirtualMachine();
 
-// Block events
+For convenience, we've included a development server with the VM. This is useful because the VM can take advantage of executing in a WebWorker, which is not permitted in a local file.

-For convenience, we've included a development server with the VM. This is useful because the VM can take advantage of executing in a WebWorker, which is not permitted in a local file. To start the server, run:
 
+## Running the Development Server
+Open a Command Prompt or Terminal in the repository and run:
 ```bash
-make serve
+npm start
 ```
-and go to [http://localhost:8080/](http://localhost:8080/) - you will be redirected to the playground, which demonstrates various tools and internal state.
+Or on Windows:
+```bash
+StartServerWindows.bat

+
+## Playground
+To run the Playground, make sure the dev server's running and go to [http://localhost:8080/](http://localhost:8080/) - you will be redirected to the playground, which demonstrates various tools and internal state.
