How to add a sample code on Playground?

Hello community!,

I’d like to issue a pull request with a sample code on Playground. How can I add my source code on it?
I checked this forum posts and official document(Use the Playground for Development - Babylon.js Documentation), but I could not find how to add it.

I’ll appreciate your response.

The playground is a place to try out your code. You can write code directly in the playground or you can copy and paste code into it. You do not need a pull request to put code into the playground. If you have code that you think beneficial to Babylon.js you send a pull request to its Github Start Contributing to Babylon.js - Babylon.js Documentation

Hope that clarifies

Sorry for late because I forgot to click “Reply” button.

Thanks for your comment!
I’ll create local dev Playground according to the post : Start Contributing to Babylon.js - Babylon.js Documentation
