## Setup

For an extended setup example, check out the /playground directory, which includes a fully running VM instance.

|
||||
## Development Server and Playground
|
||||
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:
|
||||
|
||||
```bash
|
||||
make serve
|
||||
```
|
||||
and go to [http://localhost:8080/](http://localhost:8080/) - you will be redirected to the playground, which demonstrates various tools and internal state.
