# Playground

## Introduction

The Specify Playground helps you run parsers against a token graph and see the generated output in live. It's a great tool to help you iterate on your configuration files or try new parsers on the go.

## Usage

* The left side panel contains the SDTF graph you'll run your rules against. It's editable and you're free to use your own SDTF graph which you can get with the [to-sdtf](https://docs.specifyapp.com/reference/parsers/to-sdtf) parser
* The middle panel contains your Specify configuration rule
* The right side panel displays the generated code
