# Contributing a new demo ## Preface Thanks for being interested in contributing a demo! Before you read more, have you read the [contribution guide](https://github.com/pmndrs/react-spring/blob/main/CONTRIBUTING.md) for the repo? If not, give it a look first! ## What is required All our demos are based on codesandbox templates for react-typescript. If you're going to contribute a demo, you can either copy an existing demo and tweak it or create a new one in codesandbox, export the code and add it to the repo. You should ensure your demo follows the same structure as the other ones: ``` - public - src - - App.tsx - - index.tsx - .pretterrc - package.json - tsconfig.json // I would copy this from an existing one - thumbnail.png ``` This is the minimum we require as the `App.tsx` is used to integrate with our demo hub via vite in the repo. A few other things to remember ### Thumbnail This should be included to showcase your work best! Make sure it's a 16:9 ratio. ### Package.json Ensure there's a clear name and description as these appear on the website. You should also use `tags` to highlight keywords especially the `react-spring` hooks you've used. ## When you're ready When you've finished adding your code, open a PR explaining the example, why you think it should be included and most importantly, include a sandbox link so it can be looked at and admired!
