 You can use any arbitrary string as your application id and master key. These will be used by your clients to authenticate with the Parse Server.

 After starting the server, you can visit http://localhost:1337/playground in your browser to start playing with your GraphQL API.
 
 ***Note:*** Do ***NOT*** use --mountPlayground option in production. [Parse Dashboard](https://github.com/parse-community/parse-dashboard) has a built-in GraphQL Playground and it is the recommended option for production apps.
