 Since you have already started your Parse GraphQL Server, you can now visit [http://localhost:1337/playground](http://localhost:1337/playground) in your web browser to start playing with your GraphQL API.

+
+## Using Docker
+
+You can also run the Parse GraphQL API inside a Docker container:
+
+```bash
+$ git clone https://github.com/parse-community/parse-server
+$ cd parse-server
+$ docker build --tag parse-server .
+$ docker run --name my-mongo -d mongo
+$ docker run --name my-parse-server --link my-mongo:mongo -d parse-server --appId APPLICATION_ID --masterKey MASTER_KEY --databaseURI mongodb://mongo/test --mountGraphQL --mountPlayground
+```
+
+After starting the server, you can visit [http://localhost:1337/playground](http://localhost:1337/playground) in your browser to start playing with your GraphQL API.
+
+⚠️ Please do not use `--mountPlayground` option in production as anyone could access your API Playground and read or change your application's data. [Parse Dashboard](#running-parse-dashboard) has a built-in GraphQL Playground and it is the recommended option for production apps.
+
+## Using Express.js
+
+You can also mount the GraphQL API in an Express.js application together with the REST API or solo:
+
+```js
+const express = require('express');
+const { default: ParseServer, ParseGraphQLServer } = require('parse-server');
+
+const app = express();
+
+const parseServer = new ParseServer({
+  databaseURI: 'mongodb://localhost:27017/test',
+  appId: 'APPLICATION_ID',
+  masterKey: 'MASTER_KEY',
+  serverURL: 'http://localhost:1337/parse'
+});
+
+const parseGraphQLServer = new ParseGraphQLServer(
+  parseServer,
+  {
+    graphQLPath: '/graphql',
+    playgroundPath: '/playground'
+  }
+);
+
+app.use('/parse', parseServer.app); // (Optional) Mounts the REST API
+parseGraphQLServer.applyGraphQL(app); // Mounts the GraphQL API
+parseGraphQLServer.applyPlayground(app); // (Optional) Mounts the GraphQL Playground - do NOT use in Production
+
+app.listen(1337, function() {
+  console.log('REST API running on http://localhost:1337/parse');
+  console.log('GraphQL API running on http://localhost:1337/graphql');
+  console.log('GraphQL Playground running on http://localhost:1337/playground');
+});
+```
+
+After starting the server, you can visit [http://localhost:1337/playground](http://localhost:1337/playground) in your browser to start playing with your GraphQL API.
+
+⚠️ Please do not mount the GraphQL Playground in production as anyone could access your API Playground and read or change your application's data. [Parse Dashboard](#running-parse-dashboard) has a built-in GraphQL Playground and it is the recommended option for production apps.
+
+## Running Parse Dashboard
+
+[Parse Dashboard](https://github.com/parse-community/parse-dashboard) is a standalone dashboard for managing your Parse Server apps, including your objects' schema and data, logs, jobs, and push notifications. Parse Dashboard also has a built-in GraphQL Playground that you can use to play around with your auto-generated Parse GraphQL API. It is the recommended option for production applications.
+
+The easiest way to run the Parse Dashboard is through its CLI:
+
+```bash
+$ npm install -g parse-dashboard
+$ parse-dashboard --dev --appId APPLICATION_ID --masterKey MASTER_KEY --serverURL "http://localhost:1337/parse" --graphQLServerURL "http://localhost:1337/graphql" --appName MyAppName
+```
+
+After starting the dashboard, you can visit [http://0.0.0.0:4040/apps/MyAppName/api_console/graphql](http://0.0.0.0:4040/apps/MyAppName/api_console/graphql) in your browser:
+
+<img alt="Parse Dashboard GraphQL Playground" data-echo="{{ '/assets/images/graphql/dashboard-graphql-playground.png' | prepend: site.baseurl }}"/>
